Installation

Before you begin an installation, be sure that:• Your stove and chimney connector will be far
enough from combustible materials to meet all
tested clearance requirements.
• The ﬂoor protector is large enough and is constructed properly to meet all tested requirements.
• You have all necessary permits from local authorities.
Your local building ofﬁcial is the ﬁnal authority for approving your installation as safe and determining that itmeets local and state codes.
The metal label permanently attached to the back ofevery Vermont Castings’ stove indicates the stove has
been tested and meets current UL and ULC safety
standards, and gives the name of the testing laboratory.
Clearance and installation information also is printed
on the label. When the stove is installed according to
the information both on the label and in this manual,
local authorities in most cases will accept the label as
evidence that the installation meets codes and can beapproved.
However, codes vary in different areas. Before starting
the installation, review your plans with the local building
authority. Your local dealer can provide any additional
information needed.
For any unresolved installation issues, refer to the
National Fire Protection Association’s publication ANSI/NFPA 211 Standard for Chimneys, Fireplaces, Vents
and Solid Fuel Burning Appliances. For Canada, theequivalent publication is CSA CAN-B365 Installation
Code for Solid Fuel Burning Appliances and Equipment.
These standards are the basis for many national codes.
They are nationally recognized and are accepted bymost local authorities. Your local dealer or your local
building ofﬁcial may have a copy of these regulations.
IMPORTANT: FAILURE TO FOLLOW THESE INSTALLATION INSTRUCTIONS MAY RESULT IN ADANGEROUS SITUATION, INCLUDING A CHIMNEYOR HOUSE FIRE. FOLLOW ALL INSTRUCTIONSEXACTLY, AND DO NOT ALLOW MAKESHIFT COMPROMISES TO ENDANGER PROPERTY AND PERSONAL SAFETY.

Outside Air
In some modern, super-insulated homes, there isinadequate air for combustion because of insufﬁcient
air inﬁltration into the building. Such air enters a homethrough unsealed cracks and openings. Exhaust fansfor kitchen or bath can compete with the stove for available air and compound the problem.
When poor draft is caused by a low inﬁltration rate,
opening a ground ﬂoor window on the windward sideof the house and in the vicinity of the stove will usually
alleviate the problem.
Another solution is to install a permanent outside air
supply to the stove and/or room. In fact, bringing air for
combustion from outside the home directly to the air inlet of the stove is required for new construction in someareas. The Encore NC is equipped with an outside connection as standard equipment.
Pressure variations within the house do not affect astove equipped with an outside air supply, and improved stove performance often results. An Outside Air
Adapter Kit for the Encore is available from your local
Vermont Castings dealer.

Chimney Height
Altitude affects chimney performance. When using a
6” ﬂue collar on the Encore NC, refer to Figure 2 forsuggested chimney heights at various altitudes. Chimney height should be measured from the ﬂue collar to
the top of the chimney. The recommended minimum
chimney height is 16’ (4.9 m).

What Kind of Chimney to Use

Masonry Chimneys

You must connect the Encore to a code-approved
masonry chimney with a ﬂue liner, to a relined masonrychimney that meets local codes, or to a prefabricatedmetal chimney that complies with the requirements
for Type HT chimneys in the Standard for Chimneys,
Factory-Built, Residential Type and Building Heating
Appliance, UL 103. (Fig. 3) The chimney and chimney
connector must be in good condition and kept clean.

An inspection of the chimney must conﬁrm that it hasa lining. Do not use an unlined chimney. The chimney
should have no cracks, loose mortar, other signs ofdeterioration, and blockage. Repair any defects before
the chimney is used with your stove.

A prefabricated doublewall insulated chimney

Unused openings in an existing masonry chimney must
be sealed with masonry to the thickness of the chimneywall, and the chimney liner should be repaired. Openings sealed with pie plates or wallpaper are a hazard
and should be sealed with mortar or refractory cement.
In the event of a chimney ﬁre, ﬂames and smoke may
be forced out of these unused thimbles.
The chimney should be thoroughly cleaned before use.
A newly-built masonry chimney must conform to thestandards of your local building code or, in the absenceof a local code, to a recognized national code. Masonrychimneys must be lined, either with code-approved
masonry or pre-cast refractory tiles, stainless steel
pipe, or a code-approved, “poured-in-place” liner. The
chimney’s clean-out door must seal tightly.

If you use an existing masonry chimney, it must be
inspected to ensure it is in a safe condition before
the stove is installed. Your
ST241local professional chimney
chimney types
sweep, building inspector,
or ﬁre department ofﬁcial will
12/13/99 djt
be able to inspect thechimney or provide a referral tosomeone who can.
The chimney should extend at least 3’ (914 mm) above
the highest point where it passes through a roof, and at
least 2’ (610 mm) higher than any portion of a building
within 10’ (3 m). (Fig. 4)
For proper draft and good performance, any chimneyused with an Encore should extend at least 16’ (5 m)above the ﬂue collar of the stove.

Chimney Size
An Encore with an 8” (203 mm) ﬂue collar is approvedfor venting into a masonry chimney with a nominal
ﬂue size of 8” x 8” (203 x 203 mm) or 8” x 12” (203 x
305mm), and into a round ﬂue with nominal ﬂue size of8” (203 mm). An Encore with a 6” (152 mm) ﬂue collar
is approved for venting into a masonry chimney with anominal ﬂue size of 8” x 8” (203 x 203 mm), and into around ﬂue with nominal ﬂue of 6” (152 mm).

NOTE: When installed with a 6” ﬂue collar,
the Encore may not be operated with thefront doors open.

Reference
Point

A prefabricated metal chimney must be one tested andlisted for use with solid-fuel burning appliances to theHigh-Temperature (H.T.) Chimney Standard UL-1031985 (2100°F) for the United States, and High Temperature (650°C) Standard ULC S-629 for Canada.

Whatever the ﬂue collar size, an Encore may be vented
into larger chimneys as well. However, chimneys
with liners larger than 8” x 12” (203 x 305 mm) may
experience rapid cooling of smoke and reduction indraft, especially if the chimneys are located outside thehome. These large chimneys may need to be insulatedor have their ﬂues relined for proper stove performance.
Accessories to help make the connection between
stainless steel chimney liners and your Encore areavailable through your local dealer.

Encore 1450 Non-Catalytic Woodburning Stove
Chimney Connector Guidelines
A chimney connector is the double-wall or single-wallpipe that connects the stove to the chimney. The chimney itself is the masonry or prefabricated structure that
encloses the ﬂue. Chimney connectors are used only toconnect the stove to the chimney, as in Figure 5.
Double-wall connectors must be tested and listed foruse with solid-fuel burning appliances. Single-wall connectors should be made of 24 gauge or heavier steel.
Do not use galvanized connector; it cannot withstandthe high temperatures that can be reached by thestove’s exhaust gases, and may release toxic fumes
under high heat. The connector may be 6” (152mm) or
8 “ (203mm) in diameter.
If possible, do not pass the chimney connector througha combustible wall or ceiling. If passage through a combustible wall is unavoidable, refer to the section on Wall
Pass-Throughs. Do not pass the connector through an
attic, a closet or similar concealed space. The wholeconnector should be exposed and accessible for inspection and cleaning.
In horizontal runs of chimney connector, maintain a distance of 24” (610mm) from the ceiling. Keep it as shortand direct as possible, with no more than two 90° turns.
Slope horizontal runs of connector upward 1/4” per foot(6mm per meter) going from the stove toward the chimney. The recommended maximum length of a horizontal
run is 3’ (1m), and the total length should be no longer
than 8’ (2.4m). In cathedral ceiling installations, extend
the prefabricated chimney downward to within 8’ (2.4)
of the stove.
Wear gloves and protective eyewear when drilling,
cutting or joining sections of chimney connector.

the ﬁrst crimped end into the stove’s ﬂue collar, andkeep each crimped end pointing toward the stove.
(Fig. 5)Using the holes in the ﬂue collar as guides,
drill 1/8” (3mm) holes in the bottom of the ﬁrst section of chimney connector and secure it to the ﬂue
collar with three #10 x 1/2” sheet metal screws.
Secure each joint between sections of chimney
connector, including telescoping joints, with at least
three (3) sheet metal screws. The pre-drilled holes inthe top of each section of chimney connector serve
as guides when you drill 1/8” (3mm) holes in the bottom of the next section.
Secure the chimney connector to the chimney. Instructions for various installations follow.
Be sure the stove and chimney connector are installed at the correct distances from nearby combustible materials as per tested clearance. Refer toEncore Clearance Diagrams.

NOTE: Special slip pipes and thimble sleeves that form
telescoping joints between sections of chimney connector are available to simplify installations. They often
eliminate the need to cut individual connector sections.
Consult your local dealer about these special pieces.

Double-wall Chimney Connectors
Information on assembling and installing double-wallconnectors is provided by the manufacturer of the
double-wall pipe. Follow the manufacturer’s instructions
exactly as you assemble theconnector and attach it to thestove and chimney. Usingchimneys and connectors
from the same manufacturer
makes the assembly andinstallation straightforward.
NOTE: For installations using double-wall connectors,
minimum clearances must
conform to the listed clearances in the clearance chart
on Page 15.

If the Encore is equipped with towardChimney
12/13/99 djt

the 8” ﬂue collar, an ovalto-round adapter will be needed. Double-wall oval-toround adapters are available from some manufacturers.
Your local dealer can help you select the right connector.

Securing the Single-wall Connector to a
Prefabricated Chimney
Follow the installation instructions of the chimney
manufacturer exactly as you install the chimney. The
manufacturer of the chimney will supply the accessories to support the chimney, either from the roof ofthe house, at the ceiling of the room where the stove isinstalled, or from an exterior wall.
Special adapters are available from your local dealer
which connect the prefabricated chimney to the chimney connector. The top of such adapters attach directly
to the chimney or to the chimney’s ceiling support package, while the bottom of the adapter is screwed to thechimney connector.
These adapters are designed so the top end will ﬁtoutside the inner wall of the chimney, and the bottom
end will ﬁt inside the ﬁrst section of chimney connector.
When assembled in this way, any soot or creosote falling from the inner walls of the chimney will stay inside
the chimney connector.

Freestanding Installations
If the chimney connector must pass through a combustible wall to reach the chimney, follow the recommendations in the Wall Pass-Through section later in thismanual.
The opening through the chimney wall to the ﬂue(the “breech”) must be lined with either a ceramic or
metal cylinder, called the “thimble”, which is cemented
securely in place. Most chimney breeches incorporate
thimbles, but the ﬁt must be snug and the joint between
the thimble and the chimney wall must be cemented
ﬁrmly.
A special piece called the “thimble sleeve,” slightly
smaller in diameter than standard connectors andmost thimbles, will facilitate the removal of the chimney
connector system for inspection and cleaning. Thimble
sleeves are available from your local dealer.
To install a thimble sleeve, slide it into the breech until
it is ﬂush with the inner ﬂue wall. Do not extend it into
the actual ﬂue passage, as this could interfere with thedraft.

30002425

The chimney connector may be connected to thechimney above the ﬁreplace opening or through theﬁreplace.

Above the Fireplace
The Encore may be connected to a chimney above
a ﬁreplace opening. (Fig. 8) In such installations, thestove is positioned on the hearth in front of the ﬁreplace
and the chimney connector rises from the stove top andthen angles ninety degrees back into the chimney. The
chimney liner should extend to the point at which thechimney connector enters the chimney.
If the chimney connector from your installation enters
the chimney above a ﬁreplace, follow all the guidelines
mentioned above for freestanding installations. In addition, give special consideration to the following points:• Check the clearance between the stove and thechimney connector, and any combustible trim or themantel. Use the necessary combination of mantel, trim,
and connector heat shields to achieve the required
clearances.
• Check the clearance between the chimney connector and the ceiling. If no heat shields are used, theclearance should be at least 24” (610mm). To ﬁnd out
how much this clearance may be reduced with heatshields, refer to the clearance chart on Page 15.

7Encore 1450 Non-Catalytic Woodburning Stove• The ﬁreplace damper must be sealed to preventroom air from escaping up the ﬂue. However, it must be
possible to re-open the damper to inspect or clean thechimney.

If your ﬁreplace openingfplcheightis at least 26¹⁄₂"
12/99(675mm), you may install an Encore through the opening using a “positive connection” kit, available from yourlocal dealer. These positive connection kits ensure atight ﬁt between the stove ﬂue collar and the chimney
ﬂue. (Fig. 9)

Fireplace installations, whether connected to the ﬂue
above or through the ﬁreplace opening, have special
clearance requirements to adjacent trim and the mantel.
You’ll ﬁnd the required safe clearances for Encore ﬁreplace installations on Page 12 and Figure 16.
Floor protection requirements also apply to ﬁreplaceinstallations. This information is on Page 10.

Wall Pass-Throughs
Whenever possible, design your installation so the connector does not pass through a combustible wall. If you
are considering a wall pass-through in your installation,
check with your building inspector before you begin.
Also, check with the chimney connector manufacturer
for any speciﬁc requirements.
Accessories are available for use as wall passthroughs. If using one of these, make sure it has beentested and listed for use as a wall pass-through.

ST245

Fig. 9 In this installation, the chimney connector enters theﬁreplace opening and then connects to the chimney.

In the United States, ST245
the National Fire Protection Asfireplacesociation (NFPA) has establishedguidelines for passing
flex connector
chimney connectors throughcombustiblewalls. Many
12/99
building code inspectors follow these guidelines whenapproving installations.
Figure 10 shows one NFPA-recommended method.
All combustible material in the wall is cut away fromthe single-wall connector to provide the required 12”(305mm) clearance. Any material used to close up the
opening must be noncombustible.
Three other methods are also approved by the NFPA:• Using a section of double-wall chimney with a 9”(229mm) clearance to combustibles.
• Placing a section of chimney connector inside aventilated thimble, which in turn is separated from combustibles by 6” (152mm) of ﬁberglass insulating material.
• Placing a section of chimney connector inside a
section of 9” (230mm) diameter, solid-insulated, factorybuilt chimney, with 2” (50mm) of air space between thechimney section and combustibles.
In Canada, The Canadian Standards Association has
established different guidelines. Figure 10 shows one
method, in which all combustible material in the wall is
cut away to provide the required 18” (457mm) clearance for the connector. The resulting space must remain empty. A ﬂush-mounted sheet metal cover may be
used on one side only. If covers must be used on bothsides, each cover must be mounted on noncombustible
spacers at least 1” (25mm) clear of the wall.

Heat protection is provided through the bottom heatshield. Spark, ember and thermal protection must be
provided by a ﬂoor protector constructed with noncombustible material as speciﬁed.
Most installations will require the bottom heat shield be
attached. Only when the stove is placed on a completely noncombustible surface such as unpainted concrete
over earth may it be used without the heat shield.
Even when the bottom heat shield is installed, youmust provide special protection to the ﬂoor beneath.
For installation with the heat shield attached, use anapproved 1/2” (13 mm) noncombustible hearth pad withk = 0.84 BTU/in ft2 hr °F or an equivalent material with
an R-value of at least 0.59. (Refer to “How to Determine
if Alternate Floor Protection Materials are Acceptable”
section) The ﬂoor protector may be covered with adecorative noncombustible material if desired. Do not
obstruct the space under the heater.
Protection requirements vary somewhat between theUntied States and Canada as follows:
U. S. installations the ﬂoor protector is required under
the stove and must extend at least 16” (not including
the ash lip) from the front of the stove (“F”, Fig. 12), andat least 6” from the sides and rear. (“D” and “E”, Fig.
12) It must also extend under the chimney connector
and 2” to either side. (“C”, Fig. 12) For the 8” (203 mm)
connector, the protector must be a minimum of 12”(305 mm) wide. For the 6” (152 mm) connector, theprotector must be 10” (254 mm) wide. The protector
must be centered under the connector.
To meet these requirements, a ﬂoor protector must be
at least 39” wide and 45” deep.
In Canada: A noncombustible ﬂoor protector is required
under the stove as well. The ﬂoor protector must
extend 18” (450 mm) to the front (“F”, Fig. 12), and 8”(200 mm) from the sides and rear. (“D” and “E”, Fig. 12)

Floor protection also must extend under the chimney
connector and 2” (51 mm) to either side. (“C”, Fig. 12)
For the 8” (203 mm) connector, the protector must bea minimum of 12” (305 mm) wide. For the 6” (152 mm)

How to Determine if Alternate Floor
Protection Materials are Acceptable
All ﬂoor protection must be noncombustible (i.e. metals, brick, stone, mineral ﬁber boards, etc.). Any organic
materials (i.e. plastics, wood paper products, etc.) are
combustible and must not be used. The ﬂoor protection
speciﬁed includes some form of thermal designationsuch as R-value (thermal resistance) or k-factor (thermal conductivity).
Procedure:
1. Convert speciﬁcations to R-value:i. R-value given - no conversion needed.
ii. k-factor is given with a required thickness (T) in
inches: R = 1 x T
kiii. K-factor is given with a required thickness (T) in
inches: R = 1
xT
K x 12
iv. r-factor is given with a required thickness (T) in
inches: R = r x T
2. Determine the R-value of the proposed alternate
ﬂoor protector:
i. Use the formula in Step 1 to convert values not
expressed as R.
ii. For multiple layers, add R-values of each layer todetermine overall R-value.
3. If the overall R-value of the system is greater thanthe R-value of the speciﬁed ﬂoor protector, the alternate is acceptable.

10

Step a: Use formula above to convert speciﬁcation to
R-value: R = 1 x T = 1 x 0.5 = 0.59
k
0.84
Step b: Calculate R of proposed system.
4” brick of r = 0.2, therefore:
Rbrick = 0.2 x 4 = 0.8
1/8” mineral board of k = 0.29, therefore
Rmineralboard = 1 x 0.125 = 0.431
0.29
Rtotal = Rbrick + Rmineralboard = 0.8 + 0.431 = 1.231
Step c: Compare proposed system Rtotal of 1.231 to
speciﬁed R of 0.59. Since proposed system Rtotal isgreater than required, the system is acceptable.

Floor Protection for Fireplace Installations
Do not assume that your ﬁreplace hearth is completely
noncombustible.
Many ﬁreplace hearths do not meet the “completely
noncombustible” requirement because the brick or
concrete in front of the ﬁreplace opening is supported
by heavy wood framing. (Fig. 13) Because heat passes
through brick or concrete readily, it can easily passthrough to the wood. As a result, such ﬁreplace hearths
can be a ﬁre hazard and are considered a combustible
ﬂoor.
Keep in mind, also, that many raised hearths will extend
less than the required clearance from the front of theheater when it is installed. In such cases, sufﬁcient
ﬂoor protection as described above must be added in
front of the hearth to satisfy the minimum ﬂoor protector
requirement from the front of the stove: 16” (406 mm)from the front in the United States and 18” (450 mm)
from the front in Canada.
Hearth rugs do not satisfy the requirements for ﬂoor
protection.
Fireplace installations also have special clearance
requirements to the side walls, side decorative trim, andﬁreplace mantel. This information follows in the section
on Fireplace and Mantel Trim Shields.

Encore 1450 Non-Catalytic Woodburning Stove
Keep the Stove a Safe Distancefrom Surrounding Materials
Both a stove and its chimney connector radiate heat inall directions when operating, and dangerous overheating of nearby combustible materials can occur if they
are too close to the heat. A safe installation requiresthat adequate clearance be maintained between the
hot stove and its connector and nearby combustibles.
Clearance is the distance between either your stove(measured from the bottom edge of the stove’s top
plate) or chimney connector, and nearby walls, ﬂoors,
the ceiling, and any other ﬁxed combustible surface.
Your stove has special clearance requirements thathave been established after careful research and testing to UL and ULC standards. These clearance requirements must be strictly observed.
In addition, furnishings and other combustible materials must be kept away from the stove. In general, adistance of 48” (1219mm) must be maintained between
the stove and moveable combustible items such as drying clothes, furniture, newspapers, ﬁrewood, etc. Keeping those clearance areas empty assures that nearby
surfaces and objects will not overheat.

The Encore 1450 includes a bottom heat shield that isneeded in most installations. Refer to Page 9 for more
information on required ﬂoor protection. In addition, top
exit installations that do not include wall protection must
include a vertical ﬂue collar heat shield. (Consult clearance chart on Page 15.) The vertical ﬂue collar heatshield is sold as a separate accessory.
In general, the greatest clearance is required when you
place a stove and its connector without accessory heatshields near walls without heat shields.
For example, when the Encore is installed parallel tothe rear wall and no shields are used, the rear edgeof the top must be at least 29” (737 mm) from the wallbehind it and at least 17” (432 mm) from walls on eitherside.
If the Encore is installed in a corner and no shields
are used, the corners of the stove must be at least 28”(711 mm) from nearby walls.
The least clearance is required when the connector, as
well as the wall, have heat shields or when a double
wall connector and wall shields are used.
When shields are attached to the stove or chimney
connector, they are mounted away from the stove orconnector surface on noncombustible spacers. Air ﬂowing between the stove (and/or chimney connector) andattached shields carries away heat. Do not block the air
ﬂow by ﬁlling these gaps with any material.
The shiny shield surface facing the heat source must beleft unpainted, enabling it to reﬂect heat back towards
the stove or connector and away from the wall.
Clearances may be reduced only by means approvedby the regulatory authority, and in accordance with theclearances listed in this manual.

Wood framing requires protection from radiant heat

ST247eFig. 13 Combustible supporting timbers may lie beneathﬁreplace hearths, requiring additional ﬂoor protection.

Reducing Clearances Safely with Shields
Clearance requirements are established to meet every
installation possibility, and they involve the combination
ST247
of four basic variables:

Rear exit floor dgrm
• When the chimney connector has no listed heatshield mounted on it. 12/14/99 djt• When the chimney connector has a listed heat••shield mounted on it.
When the wall has no listed heat shield mounted
on it.
When the wall has a heat shield mounted on it.

Because of their restricted air ﬂow and heat retention
characteristics, speciﬁc construction requirements andspecial clearances apply to installations into alcoves.
Refer to the diagrams on Page 10, and contact your
Vermont Castings Dealer for details before beginning
an alcove installation.
NOTE: ALCOVE INSTALLATION OF THE ENCORE
IS NOT PERMITTED IN CANADA.

Wall Shields
One way to reduce clearances is with a wall shield
constructed of 24 gauge or heavier sheet metal, or ofanother noncombustible material such as 1/2” (13 mm)
insulation board or common brick “laid on ﬂat,” with the
3¹⁄₂" (90mm) side down.
Shields must be spaced out from the combustible
surface 1" (25 mm) on noncombustible spacers, as in
Figure 14. The spacers should not be directly behindthe stove or chimney connector.
11Encore 1450 Non-Catalytic Woodburning Stove
Air must be able to ﬂow between the wall and theshield. At least 50% of the bottom 1" (25 mm) of theshield should be open and the shield must be open at
the top. Use metal screening, as in Figure 14, to keep
stray objects from falling behind the shield.
The shield for a top-exit stove must extend 10"(254 mm) above the top of the stove; for a rear exit
conﬁguration, the shield must be 36” (914 mm) high.
The shield for the chimney connector must be 30” (762mm) wide, centered behind the pipe; for installations
that use an approved prefabricated chimney to passthrough the ceiling, the chimney connector shield muststop 1” (25 mm) below the ceiling.
Air FlowWall Shield
Stud Wall
FramingDrywallA ﬁreplace installation requires special clearance between the side of the stove and the right and left walls,
between the side of the stove and the decorative side
trim on the ﬁreplace face, and between the top of thestove and the mantel.
Noncombustible shields installed 1” (25 mm) from the
combustible surface on noncombustible spacers, called
ventilated shields, may be used to reduce clearances.
To protect a mantel from the heat of an Encore in aﬁreplace installation, use a custom-made ventilated
mantel shield that is at least 48” (1219 mm) long, that iscentered over the stove. (Fig. 15) Ventilated shields forside trim must extend the full length of the trim.
An unprotected mantel (“A”, Fig. 16) cannot be morethan 9 (229 mm) deep and must have a minimum clearance of 38” (965 mm), measured from the stove’s top
plate. With a ventilated shield, this clearance may be
reduced safely to 22” (559 mm).

Unprotected side trim (C) that protrudes 3/4” (19 mm)or less from the face of a ﬁreplace must have a minimum
clearance of 10” (254 mm), measured from the stove’s
top side edge. If the trim extends more than 3/4” (19 mm),
it is subject to the requirements for wall clearance.

In top-exiting installations, the connector shield must
extend to a point exactly 36” (914 mm) above the ﬂue

If the top-exiting connector extends to the ceiling where
it connects with a prefabricated insulated metal chimney, an additional ceiling heat shield must be installedthat is 24” (610 mm) in diameter and that extends 1” (25mm) below the ceiling. The ceiling shield must be constructed of 24 gauge or heavier sheet metal, and mustbe centered on the chimney.

Operation
The Encore NC Controls
Two controls regulate the performance of the Encore
NC: a primary air control supplies oxygen for theﬁre, and a damper directs air ﬂow within the stove toactivate and deactivate the non-catalytic combustion
system. Except when starting or reviving a ﬁre, adding fuel or when the stove doors are open, the damper
should always be closed. Operation for extended periods with the bypass open could result in overﬁring of
the stove causing a possible safety hazard and damage
to the stove.

The Encore is designed to burn natural wood only; do
not burn fuels other than that for which it was designed.
You’ll enjoy the best results when burning wood thathas been adequately air-dried. Avoid burning “green”
wood that has not been properly seasoned, or cordwood dried more than two years. Do not burn construction materials; they often contain chemicals andmetals that are harmful to the stove, chimney systemand the environment. The wood should be 18-20” (457610 mm) in length.
The best hardwood fuels include oak, maple, beech,
ash, and hickory that has been split, stacked, and airdried outside under cover for at least one year.
If hardwood is not available, you can burn softwoods
which include tamarack, yellow pine, white pine, Eastern red cedar, ﬁr, and redwood. These too should beproperly dried. The basic difference between hard andsoft wood is their density. Hardwoods, because of theirgreater density, burn longer than softwoods and canincrease the time between refuelings.
Store wood under cover to keep it dry. The longer it
is stored in a dry condition, the better heating and ﬁreviewing performance you will enjoy. Even for short-term
storage, however, keep wood a safe distance from theheater and keep it out of the areas around the heaterused for refueling and ash removal.

that Work Best for You

Burn Rate

No single air control setting will ﬁt every situation. Eachinstallation will differ depending on the quality of thefuel, the amount of heat desired, how long you wish theﬁre to burn, climactic conditions; outdoor air temperature and pressure may also effect draft.

Low

From far right to 1/3
the distance to left

MediumFrom 1/3 to 2/3 the distanceto leftHigh

From 2/3 the distanceto left to far left

The control setting also depends on your particularinstallation’s “draft,” or the force that moves air from thestove up through the chimney. Draft is affected by suchthings as the length, type, and location of the chimney,
local geography, nearby obstructions, and other factors.
Refer to Pages 25-27 for details on how the installation
affects performance.
Too much draft may cause excessive temperatures inthe Encore, and could even damage the stove. On theother hand, too little draft can cause backpufﬁng into
the room and/or the “plugging” of the chimney.
How do you know if your draft is excessively high or
low? Symptoms of too much draft include an uncontrollable burn or a glowing-red stove part. A sign of inadequate draft is smoke leaking into the room through thestove or chimney connector joints, low heat output anddirty glass.
In some newer homes that are well-insulated andweather-tight, poor draft may result from insufﬁcient air
in the house. In such instances, an open window near
the stove on the windward side of the house will help
provide the fresh air needed.
Another option for getting more combustion air to thestove is to duct air directly from outdoors to the stove.
In some areas provisions for outside combustion air are
required in all new construction.
Your Encore is equipped to deliver outside air for combustion.
When ﬁrst using the stove, keep track of the air control
settings. You will quickly ﬁnd that a speciﬁc setting will
give you a ﬁxed amount of heat. It may take a week or
two to determine the amount of heat and the length ofburn you should expect from various settings.

DO NOT OPERATE THE STOVE WITH THE ASH
DOOR OPEN. OPERATION WITH THE ASH DOOROPEN CAN CAUSE AN OVERFIRING CONDITIONTO OCCUR. OVERFIRING THE STOVE IS DANGEROUS AND CAN RESULT IN PROPERTY DAMAGE,
INJURY OR LOSS OF LIFE.

Conditioning Your Stove
Cast iron is extremely strong, but it can be broken witha sharp blow from a hammer or from the thermal shockof rapid and extreme temperature change.
The cast plates expand and contract with changes intemperature. When you ﬁrst begin using your Encore,minimize thermal stress by allowing the plates to adjust
gradually during three or four initial break-in ﬁres.

Starting and Maintaining a Wood Fire
Burn only solid wood in the Encore, and burn it directlyon the grate. Do not elevate the fuel. Do not burn coalor other fuels.
The bypass damper must be open when starting aﬁre or when refueling.
Do not use chemicals or ﬂuids to start the ﬁre. Do
not burn garbage. Never use ﬂammable ﬂuids suchas gasoline, gasoline type lantern fuel, kerosene,
charcoal lighter ﬂuid, naptha, engine oil or similar
liquids to start or “freshen up” a ﬁre in this heater.
Keep all such liquids well away from the heater
while it is in use.

Most installations do not require a large amount of combustion air, especially if adequate draft is available. Do
not attempt to increase the ﬁring of your heater byaltering the air control adjustment range outlined inthese directions.
Use the following air control settings as a starting point
to help determine the best settings for your installation.
Each is described as a fraction of the total distance thelever may be moved from right to left.

Refuel While the Embers Are Still Hot
When reloading, best results will be achieved if you ﬁrst
de-ash the stove by stirring the fuel bed to allow ash to
fall through the grate into the ash pan.
Do not break the charcoal into very small pieces orpound or compress the charcoal bed.
It is important that air can circulate through the charcoal
bed while the heater is in operation. Larger pieces ofcharcoal allow more air to circulate under the wood,
resulting in the ﬁre reviving more quickly.
ST265

Fig. 39 Add larger pieces of wood as the ﬁre begins to burnwell.

During the break-in ﬁres, do not let the stove get hotter
than 500°F (260°C)

top thermometer. Adjust
the air control lever as necesgood firesary to control the ﬁre.

12/99

Some odor from the stove’s hot metal, the paint, andthe cement is normal for the ﬁrst few ﬁres.
NOTE: Some chimneys need to be “primed,” orwarmed up, before they will draw sufﬁciently to starta ﬁre. To correct this situation, roll up a couple piecesof newspaper, place them on top of the kindling andtoward the back of the stove, light them, and close thedoors. This will encourage smoke to rise rapidly, encouraging a good draft.
Once the draft is established, open the front door andlight the rest of the fuel from the bottom. Do not lightthe main bed of fuel until the chimney begins drawing,
and repeat the procedure as often as necessary if theinitial attempt is unsuccessful.
If your Encore has been broken-in previously using,continue to build the ﬁre gradually. Add larger wood witha diameter of 3-4” (76-102 mm). Continue adding split
logs of this size to the briskly-burning ﬁre until there isa glowing ember bed at least 3” (76 mm) deep. A goodember bed is necessary for proper functioning of the
combustion system and may take an hour or more toestablish.

For best results when refueling, wear stove gloves toprotect your hands, add fuel while the stove still has
plenty of glowing embers to re-kindle the ﬁre, andinclude some smaller pieces of wood in the new fuelload to help the stove regain its operating temperature
quickly. Use this sequence as a guide to successfulrefueling:
1. Open the damper.
2. De-ash the stove as described above. Open thefront doors and check the level of ash in the ash
pan. Empty the pan if necessary and replace it in thestove. Close the front doors.
3. Open the griddle, load the wood (smaller piecesﬁrst), and close the griddle.
4. Allow the stove to regain its “thermal momentum”
before closing the damper. This may take 15--20
minutes.
5. Close the damper and set the air control lever for thedesired heat output. When the surface temperaturereaches 450°F (230°C), adjust the air control for theamount of heat you desire.
NOTE: If the charcoal bed is relatively thick {about 2”3” (52-76 mm)} deep, and if your fuel is well seasoned,
it is possible to add fresh fuel (smaller pieces ﬁrst),
close the door and damper, and reset the primary aircontrol for the desired heat output within ﬁve minutes.

You should remove ash before it reaches the top of theash pan. Check the level at least once a day. Every few
days, clear any ash from the outer edges of the ﬁrebox
and the cavity areas of the stove. Most of the ash will
fall through the grate. Slice or stir the ash with a shovel
or poker so that it falls through the grate slots.

from falling on the ﬂoor, do not tilt the ash pan forward.
If the stove is in operation, close the ash door while
disposing of the ash.
Properly dispose of the ash in a metal container witha tight-ﬁtting lid. Store the container outdoors awayfrom all combustible material.
Return the ash pan to its original position in thestove, and close and latch the ash door.
Do not operate the stove with the ash door open.
This will result in over-ﬁring, and could cause damage to the stove, void the warranty, or even lead to ahouse ﬁre.

Empty the ash pan regularly, typically every one tothree days. The frequency will vary depending on how
you operate your Encore: ash will accumulate faster athigher heat outputs.
Remove ash frequently and place it outdoors in a
metal container with a tight-ﬁtting lid. Place the closed
container of ash on a noncombustible ﬂoor or on the
ground, well away from all combustible materials, pending ﬁnal disposal. If the ash is disposed of by burial insoil or otherwise locally dispersed, it should be kept in
the closed container until all cinders have thoroughlycooled.
You can use wood ash as a garden fertilizer.
CAUTION: Never use your household or shop vacuum
cleaner to remove ash from the stove; always remove
and dispose of the ash properly.

Draft Management
A stove is part of a system which includes the chimney, the operator, the fuel and the home. Each part ofthe system affects how well the stove operates. When
there is a good match between all the parts, the system
works well.
Wood stove or insert operation depends on natural(unforced) draft. Natural draft occurs when the smoke
is hotter (and therefore lighter) than the outdoor air
at the top of the chimney. The larger the temperature
difference, the stronger the draft. As the smoke rises
from the chimney it provides suction or ‘draw’ that pulls
air into the stove for combustion. A slow, lazy ﬁre withthe stove’s air inlets fully open indicates a weak draft.
A brisk ﬁre, supported only by air entering the stove
through the normal inlets, indicates a good draft. The
stove’s air inlets are passive; they regulate how much
air can enter the stove, but depend entirely on the draftof the chimney.
Depending on the features of your installation - (i.e.
metal or masonry chimney installed, inside or outside
the house, matched to the stove’s outlet or oversized) your system may warm up quickly or it may take a while
to warm up and operate well. With an ‘airtight’ stove or
insert, one which restricts the amount of air getting into
the ﬁrebox, the chimney must keep the smoke warm all
the way to the outdoors. Some chimneys do this better
than others. Here is a list of features and their effects.

Masonry Chimney
Masonry is a traditional material for chimneys, but it
can perform poorly when it serves an ‘airtight’ stove.
Masonry is a very effective ‘heat sink’ - it absorbs a lotof heat. It can cool the smoke enough to diminish draft.
The bigger the chimney, the longer it takes to warm up.
It’s often very difﬁcult to warm up an outdoor masonrychimney, especially an oversized one, and keep it warm
enough to maintain an adequate draft.

Metal Chimney
Most factory-made metal chimneys have a layer of
insulation around the inner ﬂue. This insulation keeps
the smoke warm. The insulation is less dense than masonry, so a steel chimney warms up more quickly thana masonry chimney. Metal doesn’t have the good looksof masonry, but it often performs much better.

Indoor / Outdoor location
Because the chimney must keep the smoke warm, it isbest to locate it inside the house. The relatively warm
house then surrounds the chimney keeping it warm.
This also means that heat from the chimney walls willtransfer to the house and not be wasted outdoors. An
indoor chimney will not lose its heat to the outdoors, so
26

it takes less heat from the stove to heat it up and keep
it warm.

Flue Sizing
The interior size of a chimney for an ‘airtight’ stoveshould match the size of the stove’s ﬂue outlet. When achimney serves an airtight stove, “more” is not “better”;
in fact, it can be a disadvantage. Exhaust gases move
more slowly through larger chimneys and can lose
more heat to the chimney walls. This weakens the draft
strength. If an oversized ﬂue is also outside the house,
the heat it absorbs gets transferred to the outdoor air
and the ﬂue is further cooled.
It’s common for a masonry ﬂue, especially one serving
a ﬁreplace, to be oversized for the stove. It can takequite a while to warm up such a ﬂue, and the results
can be disappointing. The best solution to an oversized
ﬂue is an insulated steel chimney liner, the same diameter as the stove or insert’s ﬂue outlet; the liner keeps
the exhaust warm, and the result is a stronger draft. An
uninsulated liner is a second choice - the liner keeps
the exhaust path restricted to its original size, but the
air around the liner must still be heated. This makes thewarm-up process take longer.

Pipe & Chimney Layout
Every turn the exhaust must take as it travels to thechimney top will slow it down. The ideal pipe and chimney layout is straight up from the stove, and into a vertical chimney. If you are starting from scratch, use thislayout if possible. If the stovepipe must turn to enter achimney, locate the thimble about midway between thestove top and the ceiling. This achieves several goals:
it allows the exhaust gases to speed up before turning,it leaves some pipe in the room for heat transfer, andgives you long-term ﬂexibility to install a future stove
without relocating the thimble.
There should be no more than 8 feet (2.4m) of singlewall stove pipe between the stove and a chimney; longer runs can cool the exhaust gases enough to cause
draft and creosote problems. Use double-wall stove
pipe for long runs.

Single venting
Each ‘airtight’ stove requires its own chimney. If an airtight stove is vented to a ﬂue that also serves an open
ﬁreplace, it is easier for the chimney draft to pull air
in through those channels than it is to pull air throughthe stove, and performance suffers. Imagine a vacuum
cleaner with a hole in the hose to see the effect here.
In some cases the other appliance can even cause anegative draft through the airtight, and result in a dangerous draft reversal.
30002425

Encore 1450 Non-Catalytic Woodburning Stove
Creosote

Draft Testing

Creosote is a by-product of slow wood-burning. It is anorganic tar that can condense in the ﬂue if the exhaustgases cool too much. Condensed creosote is volatile,and can fuel chimney ﬁres if it gets hot enough. All thefactors that affect chimney draft also affect creosote
condensation - so use installation features and operational steps that encourage good draft and minimize
creosote production.
Because letting the smoke cool off and slow down is
one of the keys to creosote production, it makes sense
to line a chimney to match the stove’s outlet size, forsafety reasons as well as performance. Canadian law
requires a matching liner to serve any stove or insert
vented through a ﬁreplace chimney; in the US, the National Fire Protection Association recommends a liner if
the chimney is more than three times bigger (in squarearea) than the outlet on the stove or insert. Some localities enforce the NFPA guidelines as part of their building codes.

An easy way to test your chimney draft is to close thestove’s damper, wait a few minutes to let the airﬂow
stabilize, then see whether you can vary the strengthof the ﬁre by swinging the air control open and closed.
Results are not always instant; you may need to waita few minutes for a change in the air control setting tohave an effect on the ﬁre. If there’s no change, then thedraft isn’t strong enough yet to let you close the damper,and you’ll need to open it for a while longer and manage
the ﬁre with the air inlet until the draft strengthens.
Test chimney draft with a draft gauge.

Fuel
Even the best stove installation will not perform wellwith poor fuel. The best fuel is hardwood that has airdried 12-18 months and is stored, covered from theelements. Softwoods burn well, but not as long as hardwood. ‘Green’ wood has more moisture in it; it will burn,but more of the heat from the ﬁre is needed to drive theextra moisture off the wood. This reduces the amountof heat that reaches your home and can contribute to acreosote problem. There are moisture meters available
for ﬁrewood; you can also judge your wood by its appearance and weight. If you get it green, lift a piece andget a sense of its weight; it can lose a third or more of
its weight as it dries. Also look at the ends of a log; as it
dries it shrinks and often cracks. The more weathered
and cracked a piece is, the drier it is.

Back-pufﬁng

Negative Pressure
Good draft also depends on a supply of air to the stove;a chimney can’t pull in more air than is available to it.
Sluggish draft results when a house is tight enough toprevent the ready ﬂow of air to the stove, or by competition between the stove and other equipment thatremoves air from the house - especially power-driven
equipment like range hoods, clothes dryers, etc. If thechimney draws well with all other equipment turnedoff (or sealed, in the case of ﬁreplaces and/or otherstoves), then you simply need to be careful with timing
the use of the other equipment. If you need to crack anearby window or door to enable the chimney to pullwell, that’s a sign that you should install an outside-air
intake to bring combustion air directly to the stove. For
most of our stoves, adapters are available to connect
an air duct for outdoor combustion air.

Conclusion
Wood-burning is an art rather than a science. Once thestove and chimney system are in place, you can only
vary your technique, mostly your timing, to achieve
good results. If you keep track of your burning habits
and relate them to their effects on the stove’s operation,
you’ll be rewarded with good performance and a safe
system.

“Back-pufﬁng” results when the ﬁre produces volatilegases faster than the chimney draft pulls them out of
the ﬁrebox. The gases back up in the ﬁrebox until they
are dense enough and hot enough to ignite. If yourstove back-puffs, you should open the damper to direct
more heat up the chimney to allow the smoke to riseto the ﬂue more quickly, let more air into the ﬁrebox.
Smaller loads of wood, larger pieces of wood andavoiding overly dry wood loaded into a very hot stove
may help this problem. If back-pufﬁng persists, contact
your dealer or qualiﬁed chimney sweep to help diagnose the problem.

Maintenance
Keep Your Stove Looking New
and Working Its BestLet the ﬁre in the stove go out and allow the stove tocool completely before beginning any maintenanceprocedure.

Care of the Cast Iron Surface
An occasional dusting with a dry rag will keep the painted
cast iron of your Encore looking new.
The stove’s paint can be touched up as needed. First,
mask the areas, such as enamelled parts, glass, or
handles, around the area to be painted. Clean the areawith a wire brush to remove any loose paint or dust.
Remove the griddle and set it aside.
Then, touch up the stove with Vermont Castings’ hightemperature stove paint. Apply the paint sparingly; twolight coats of paint are better than a single heavy one.

Care of the Porcelain Enamel Surface
Use a dry or slightly damp rag or soft brush to remove
spills or stains. For difﬁcult jobs that require a cleaning
agent, use only a kitchen appliance cleaner or polish
recommended for use on enamel surfaces.

Removing the Glass
1. Remove the right and left door assemblies by raising
the door until the lower hinge pin clears its drilling;
then, angle the door bottom slightly outward andpull down to release the upper hinge pin. Place thedoors face down on a padded work surface.
2. Remove the screws that hold the retainer clips inplace, and remove the clips.
3. Carefully lift the broken glass panel from the door.

Installing the Glass
Check the gasket around the window; it should be softand resilient so the glass will seal properly against thedoor. Replace the gasket if it has hardened or if it iscompressed.
1. Center the ﬁrst pane of glass on the gasket. Be sure
to place the glass so the infrared reﬂective coating ison the exterior side.

Rinse the glass thoroughly.
Dry the glass completely.

Replace Broken Glass Immediately
Do not operate your stove if the glass in the doors isdamaged.
If you need to replace the glass, use only the high temperature ceramic glass supplied by Vermont Castings.
Do not use substitutes. Be sure to specify left or rightglass; the panels are not interchangeable.

Adjust the Damper as Needed
The tension on the Encore’s damper is adjustable tocompensate for compression of the gasket that seals
the damper to the upper ﬁreback. To adjust the damper:
1. Remove the griddle. Loosen the lock nut at the center of the damper.
2. Turn the pressure screw approximately one half turnclockwise.

The Encore’s front doors, as well as its ash pan door,
should close securely to prevent accidental opening and to keep air from leaking into the stove. On
adequately adjusted doors, the handles should resist
slightly as they are turned to the closed position and thedoors themselves should be drawn slightly toward thestove.

If you need to change a gasket, ﬁrst obtain an appropriate replacement from your Vermont Castings’ Authorized Dealer.

Over time, the gasket around the doors will compress
and the latches may need adjustment.

The procedure for replacing gaskets is the same regardless of the gasket location. Follow these steps:

To adjust the latches on the doors, loosen the small
lock nut, rotate the striker screw a half-turn, and retighten the small lock. Hold the striker screw to keep itfrom turning as you tighten the lock nut. Make repeatedsmall adjustments until the setting is right.

1. Remove the existing gasket by grasping an end andpulling ﬁrmly.

Wait until the ﬁre is out and the stove has cooled. Be
sure to follow the standard safety procedure for working
with dusty materials: Wear safety goggles and a dustmask.

2. Use a wire brush or the tip of a screwdriver to clean
the channel of any remaining cement or bits of gasket.
(Fig. 46) Remove stubborn deposits of cement with acold chisel if necessary.

3. Determine the correct length of the appropriatesized gasket by laying it out in the channel. Allow an
extra 1-2” (25-50 mm), and mark the spot to be cut.
(Fig. 47)

5/16” diameter gasket seals the following parts:• The ﬂue collar to the stove back• The lower ﬁreback to the sides• All connections between the major stove plates

4. Remove the gasket from the channel, place it on awood cutting surface, and cut it at the marked spot witha utility knife. Twist the ends slightly to keep the gasket
from unraveling.

5. Lay an unbroken 1/8” (3mm) bead of gasket cementin the newly-cleaned channel.
6. Starting at one end, press the gasket into the channel. (Fig. 47) Ensure a good joint where the gasket
meets before trimming any excess. Do not overlap thegasket ends or leave ends with ragged edges.

8. Clean any excess cement from around the channel, then let the cement that holds the new gasket dry
thoroughly.

Adjust the Door If Necessary
The stove’s door(s) may need adjustment after you
have regasketed it. Initially, it may require loosening toaccommodate the new gasket; after a few weeks, it
may need tightening to compensate for compression of
the new gasket. The directions for adjusting the doors
are on Page 28.

All Gasketed Construction
Other gaskets form seals between non-moving parts,
but these are not subject to the same wear and deterioration as gaskets on moving parts. It is unlikely thatyou will ever need to replace these gaskets unless theinvolved parts are disassembled and then put back
together. If this is the case, the job should be done only
by a qualiﬁed service technician.

Creosote
Your Encore is designed to reduce creosote build-up
signiﬁcantly. However, regular chimney inspection andmaintenance must still be performed. For safety, goodstove performance, and to protect your chimney andchimney connector, inspect your chimney and chimney
connector on a regular schedule. Clean the system ifnecessary. Failure to keep the chimney and connector
system clean can result in a serious chimney ﬁre.
When wood is burned slowly, it produces tar, organic
vapors and moisture that combine to form creosote.
The creosote vapors condense in the relatively coolchimney ﬂue of a slow-burning ﬁre. As a result, creosote residue accumulates on the ﬂue lining. When ignited, this creosote makes an extremely hot ﬁre within the
ﬂue system that can damage the chimney and overheat
adjacent combustible material. If a signiﬁcant layer ofcreosote has accumulated —1/8” (3mm) or more — itshould be removed to reduce the risk of a chimney ﬁre.
To reduce the amount of creosote that may form, remember to provide adequate air for combustion and to
strive for small, intense ﬁres rather than large, smoldering ones.
You can never be too safe. Contact your local ﬁreauthority for information on what to do in the event ofa chimney ﬁre, and have a clearly understood plan on
how to handle one.
You should inspect the system every two weeks during
the heating season as part of a regular maintenanceschedule. To inspect the chimney, let the stove coolcompletely. Then, using a strong light, sight up throughthe ﬂue collar into the chimney ﬂue. If it is not possible
to inspect the ﬂue system in this fashion, the stove must
be disconnected to provide better viewing access.
Clean the chimney using a brush the same size andshape as the ﬂue liner. Flexible ﬁberglass rods are used
to run the brush up and down the liner, causing any
deposits to fall to the bottom of the chimney where they
can be removed through the clean-out door.
Clean the chimney connector by disconnecting the sections, taking them outside, and removing any deposits
with a stiff wire brush. Reinstall the connector sections
after cleaning, being sure to secure the joints between
individual sections with sheet metal screws.
If you cannot inspect or clean the chimney yourself,contact your local Vermont Castings’ Dealer or a professional chimney sweep.

Maintenance Schedule

The Chimney Connector

The Stove

TWO WEEKS:• Inspect the chimney connector and chimney. Clean if
necessary.
TWO MONTHS:• Inspect the chimney and chimney connector. Pay
particular attention to the horizontal runs of chimney
connector, and the elbows. Clean the system if necessary.
ANNUAL SPRING CLEANING:• Disassemble the chimney connector and take it
outdoors for inspection and cleaning. Replace weaksections of connector.
• Inspect the chimney for signs of deterioration. Repairs to a masonry chimney should be made by aprofessional mason. Replace damaged sections ofprefabricated chimney. Your local Vermont Castings
dealer or a chimney sweep can help determine whenreplacement is necessary.
• Thoroughly clean the chimney.

DAILY:• Clear any ash build-up from around the air holes andcombustion ﬂow path in the lower ﬁreback.
• Ashes should be removed before they reach the topof the ash pan. Check accumulation at least once aday.
• Keep the area around the stove clear of any combustible materials such as wood, furniture or clothing.
TWO MONTHS:• Check door handle to be sure it is working properly.
Gasketing becomes compressed after a period oftime. Adjust handle tightness if necessary.
• Check leg bolts and heat shield screws; tighten if
necessary.
ANNUAL SPRING CLEANING:• Check gasketing for wear, and replace if necessary.
• Remove ashes from the ash pan and replace with amoisture absorbing material (such as kitty litter) to
keep the interior of the stove dry.
• Clean the dust from the inner sides of bottom, rear or
pipe heat shields if your stove is equipped with them.
Clean surfaces are better heat reﬂectors than dirty
surfaces.
• Touch up the black paint.
• Inspect for and remove ash build-up behind the combustion package. This should be done in conjunction
with annual cleaning of the chimney connector since
this inspection is most conveniently done through theﬂue collar opening. Inspect the passages to eitherside of the combustion package (a mirror will be
helpful) and vacuum away ash using a ﬂexible vacuum hose inserted into each passage. Care should betaken not to damage the white ﬁbrous material in thisrear chamber. (Fig. 48)
