Planning Information
Planning an installation is very important to ensure
safety and to save time and money. An installer must
predetermine where a fireplace will be set and plan how
the chimney system will be run.
Also, when planning your installation, consider finishingmaterials you will be using for hearth and walls.
What to consider:
1. The fireplace bottom must be flush with the top of
the material used for the hearth.
2. If you are using a thick stone or brick, you may
want to consider mounting the firebox further out toachieve the amount of inset from the stone face tothe unit face.
3. Be sure to follow all safety guidelines described inthis manual when choosing the materials for construction.

Mounting the Fireplace
The fireplace is shipped with lifting handles attached toeach side with steel straps. NOTE: The lifting straps areintended for lifting the fireplace from the skid and final
positioning. The fireplace should remain on the skid
until final positioning. After the fireplace is in position,
the lifting handle and straps may be removed or left inplace.
A fireplace may only be mounted on the following surfaces:
1. A flat combustible surface.
2. A raised wooden platform.
3. A concrete block or other solid object placed beneatheach of the four (4) corners of the fireplace.
The fireplace must be spaced 1/2” (13 mm) from a
combustible back wall and 1/2” (13 mm) from a combustible side wall or support. (Page 15, Fig. 22)

10Z\x”
16Z\x”In planning a chimney system, it is important to know:
1. The height of a chimney is measured from the hearth
to the exit point on the termination.
2. A chimney cannot be offset more than 30° from a
vertical plane.
3. A chimney may run straight up or it may be necessary to offset it to avoid obstructions.
4. The maximum length of an angled run (total chimneysystem) is 20 feet.
5. No more than 2 offsets (4 total 30° elbows in U.S./or
2 total 45° elbows in Canada) per fireplace may be
used.
6. A guy wire stabilizer is required for chimneys extending more than 6’ (1.8 m) above a roof line.

The Ten Foot Rule
The majority of U.S. building codes specify a minimum
chimney height above the roof top. The “Ten Foot Rule”
is a fire safety rule rather than a rule to ensure proper
draft. To ensure proper draft, it is recommended thatyou always meet or exceed the “Ten Foot Rule,” especially when installing a termination on a high pitch roof.
(Fig. 6)The key points of the “Ten Foot Rule” are:1. If the horizontal distance from the chimney to thepeak of the roof is 10’ (3 m) or less, the top of thechimney must be at least 2’ (610 mm) above thepeak of the roof, but never less than 3’ (914 mm)
in height above the highest point where it passes
through the roof.
2. If a horizontal distance from the chimney to the peakof the roof is more than 10’ (3 m), a chimney heightreference point is established that is on the surfaceof the roof a distance of 10’ (3 m) from the chimney
in a horizontal plane. The top of the chimney must be
at least 2’ (610 mm) above the reference point, butnever less than 3’ (914 mm) in height above the highest point where it passes through the roof.

Installation

Chimney Supports
The SK chimney system can be supported by the fireplace for vertical chimney heights up to 30’ (9 m) above
the hearth. Chimney supports are required if the verticalheight exceeds 30’ (9 m). Locate chimney supports
at ceiling holes or other structural framing at 30’ (9 m)intervals. Spacing between chimney supports must notexceed 30’ (9 m). Use Chimney Support Model SKCS8.
(NOTE: The SKCS8 cannot be mounted directly tothe fireplace.) Support provided by elbow straps fulfills
the support requirement only if they are spaced as previously described. (A chimney support is 2¹⁄₂" (64 mm)long when installed.)
Angled chimney runs require a support every 6’ (1.8 m)
in addition to the elbow straps. Chimney supports areused for this function. (Fig. 7)

Chimney Support Strap

Insulating Fireplace Enclosure
for Cold Climates
If you live in a cold climate, it is not required but
highly recommended that you insulate the fireplaceenclosure to reduce cold air penetration as much as
possible.
Insulate the base of the fireplace with a noncombustible insulation rated for a minimum of 300° F. Insulating is very important for an outside wall installation
over a concrete slab. If the fireplace is installed ona platform, insulation should be placed on top of theplatform before the fireplace is set in place. (Fig. 8)
When a fireplace is installed in a chase or on an
outside wall, the enclosure should be treated like any
outside wall in a home. Insulation should be installedon the inside wall as well as the outside wall(s). In achase, it is also a good idea to install a firestop at thefirst ceiling level above the fireplace and enclose thechase with the sheeting material. Insulation may thenbe installed above sheeting material to assure thespace around the fireplace is well sealed. (Fig. 3)
When installing the chimney, DO NOT caulk between
the outer pipe of the chimney and the firestops. It isvital that some air be allowed to flow through this verythin gap.

Chase Installation

8/21/00

A chase is a vertical box-like structure which encloses
the fireplace and/or chimney. A chase is typically built
on the outside of the house with the fireplace opening
cut into the outer wall of a room. (Page 5, Fig. 2)

To minimize air infiltration from the chase to the home,seal all joints between the finished wall and the fireplace sheet metal. Use only noncombustible materials, such as rock wool, plaster or mortar to seal thesejoints.
CAUTION: When installing a fireplace in an insulated enclosure, be sure all required air spaces
are maintained. (Page 15, Fig. 22)

If you need help in determining fireplace location or how
the chimney system should be run, contact your Vermont Castings dealer for assistance.

Framing

Chimney Set-Up

Framing can be constructed before or after the fireplaceis set in place, however, most installers build the frame
before setting the fireplace.

Since you have already planned the chimney run, you
should know exactly how the installation is to be accomplished - the amount of pipe required, the number of
elbows, if any, and type of termination to be used.

Frame the fireplace opening with 2 x 4 lumber or
heavier materials. Refer to framing dimensions shownin Figure 1.
NOTE: Framing should be positioned to accommodate
wall covering and fireplace facing material.

Install Electrical Wire
This fireplace is wired for the optional FK26STRAT fan
kit. The fan requires 120VAC, 60 Hz power which may
be connected to the right side of the fireplace using theromex pigtail provided with the unit. This power must
be completed before the fireplace is secured and finish
material applied. The romex pigtail should be ocnnected
to house power inside a junction box which includes
wall switch or rheostat.
1. Attach the white wire from house power to the whitewire of the romex pigtail and secure with a wire nut.
2. Attach the black wire from the house power to theblack wire of the romex pigtail and secure with a wirenut.
3. Attach the ground wire from house power to theground wire of the romex pigtail and secure with awire nut. (Fig. 9)
IMPORTANT: The wire nuts must be tight.
NOTE: Check local building codes to determine if ajunction box is required at the romex pigtail/house wire
connection. Also read junction box and speed control(SCVS) installation instructions.

CAUTION: Report to your dealer any parts damaged
in shipment, specifically check the end connection ofchimney sections and elbows.
Note: Fireplaces may use MHSC Model SK8, orModel S (three wall) chimney systems. The Stratton
Series Fireplace will accept the SK8 chimney system as
shipped; but a TWABR adapter collar is required whenusing the Model S (triple wall) chimney system. The
installation procedure described in this manual applies
only to the SK8 system. Either chimney system may be
used, but the systems may not be mixed. The fireplacemust be modified to install the TWABR adapter. (Fig.
10)

Straight-Up Chimney Installation
To mark the centerline of the flue, put the fireplace infinal position and measure out from the wall: 9¹⁄₂" (241mm). Mark a spot on the ceiling directly above the fireplace. Draw a line parallel to the back wall through thismark. (Fig. 10)
Using a plumb bob positioned directly over center pointof fireplace flue collar, mark the ceiling to establish thechimney center point. (Fig. 10)

Offset Installation
In order to clear an obstruction, it may be necessary tooffset the chimney from vertical. This is accomplishedby using the elbows. Use the 30° Offset Elbow table on
Page 6 to determine proper offset and parts required.
Each offset requires two (2) elbows. The second elbow
is equipped with support straps. It is very important toinstall the second elbow in each offset as close to theceiling or support as possible so the elbow straps canbe secured to framing members and help support theweight of the chimney.
Determine offset distance of the chimney arrangementfrom the centerline of the fireplace to the centerline of
the chimney where it is to pass through the ceiling.
Locate the center point of the chimney on the ceilingas though a straight up chimney arrangement is to be
used. Measure your offset dimension from the straightup chimney center point on the ceiling.

When the finished extended hearth is added, the topof the finished hearth must be flush with the bottom of
the fireplace. “Z” shaped metal safety strips have been
supplied with the fireplace and are required for most
installations. The safety strips provided have a 1” offset.
For applications with a greater offset, “Z” shaped strips

Note: Safety
strips are not required over noncombustible floors where all supports at the base of the fireplace are noncombustible.

Nailing Flanges
1. This unit is shipped with four (4) nailing flanges premounted on either side of the fireplace to accommodate two (2) different drywall thicknesses. The 1/2”
drywall flanges are shown in Figure 13 while the top
and bottom flanges are for 5/8” drywall.
2. Bend the desired flanges out 90° on both sides ofthe fireplace. Slide the fireplace into the framed
opening until the flanges contact the front surfacesof the framing. Level the unit and secure firmly inplace.
WARNING: Risk of fire may occur if a 1/2” minimum
spacing is not maintained between the fireplace andframing members.

Installing Outside Air Kit
An outside air kit may be installed on the Stratton. The
AK-MST allows for 100% of required combustion air tocome from a source outside of the house. If desired, or
if local codes mandate the use of an air kit, then an AKMST is required to complete the installation (from air kit
to the outdoors). If the outside air kit is to be used, the
AK-MST MUST be installed BEFORE the fireplace is
enclosed. Also, the internal outside air cover plate
must be closed by moving to the up position as
30004508

Internal Outside Air Cover Plate(Shown in the closed position for
use with AKMST)FP1862
shown in Figure
14. This will prevent cold air fromnailing flanges
entering the home.
5/08 djt
NOTE: Four (4) inch Class 1 air duct, material or metalduct (not supplied) may be used with AK-MST. (Forinstallation in New York State, only aluminum, noncombustible flexible or type “O” metal ducting ispermitted.)

Installation Precautions
The duct termination should be located so it is exposed
to an out-of-doors opening of at least 100 square inches. If the duct termination must be located in a crawl
space or basement, be sure the termination area has
100 square inches of ventilation opening to outside air.
The duct termination must be located so it does notcompete for air flow with exhaust fans, gas vent hoods
or other air consuming devices or appliances. It mustnot be blocked by rafters, insulation materials or otherobstructions. The less restrictive the air supply, the better the AK-MST will perform.
It is a good practice to protect your hands and eyesduring installation by wearing work gloves and safety
glasses.
CAUTION: Do not install the air kit termination intoa garage or other area that could contain flammableliquids or fumes, or into an attic space.

Installation Instructions
Determine the location of the fireplace as describedin the fireplace Installation Manual. Then plan locationof the duct termination and the route of the duct run
between the fireplace and the duct termination.
The duct run must be limited to a maximum distanceof 40 feet (12 m) from the fireplace pipe collar to duct
termination. This will provide the least restriction to air
flow. No more than four (4) 90° elbows may be used.
11Vermont Castings Stratton
The duct run may be horizontal, vertical, inclined or any
combination of these. Vertical duct runs must be at least
three (3) feet below the fireplace chimney flue exit. (Fig.

In Canada, an SR/C
attic insulation shield is required to prevent attic insulationfrom contacting the chimney sec11/20/97
tion. Framing dimensions for the chimney hole shouldmeasure 14¹⁄₂” x 14¹⁄₂” (368 x 368 mm). An attic shield
MUST be installed on top of attic joists (above the floor
level). (Fig. 21)
CAUTION: In the U.S., it is a good idea, although notalways required, to install an attic insulation shieldwhen blown-in insulation is to be used in the attic.

Chimney Supports
If chimney supports are required, they are installedin the same manner as elbows. Nail chimney support straps to adjacent structural framing, as shown in
Figure 19. Bend straps as necessary and make surethey are secure so they will support the weight of thechimney. A chimney support is 2¹⁄₂" (64 mm) long when
installed. Consider this dimension when determining
how many straight chimney sections are needed.
NOTE: Chimney supports are generally used in longruns in a chase installation.

Additional Ceilings
If you encounter additional ceilings, repeat the steps
outlined for the first ceiling installation. See the firestop
illustration in Figure 20.

Penetrating the RoofRun pipe to the roofline. Since the chimney system
must be vented to the out-of-doors, you must use anapproved MHSC termination.
If a chase is used, refer to the installation manual provided with the termination cap.

Locate Chimney Centerpoint on Roof

The size of the roof hole varies with the type of chimney
termination to be used. Refer to installation instructions
provided with the chimney termination to correctly size
the roof hole.
There must be a 1Z\x” (38 mm) air space between outermost portion of chimney sections and any adjacentcombustible surfaces. (Combustible surfaces include
burnable materials such as: ceiling members, joists,flooring, combustible insulation and roof structures.)WARNING: Do not pack required air spaces withinsulation or other materials.
Mark an outline of the roof hole using the nail as a centerpoint. Note: Hole dimensions given in the chimney
top installation instructions are horizontal dimensions;
therefore, the hole size must be marked on the roof accordingly.
Cover the opening of the installed chimney so debris
cannot get into the system.
Cut and frame the hole. It is good practice to use framing lumber that is the same size as the rafters. Install
the frame securely because the chimney top and flashing anchored to the frame must be able to withstandheavy winds.

Install Remainder of Chimney Sections
Since you have preplanned the height of your termination according to the Ten Foot Rule, continue to installpipe to the predetermined height.
Check the chimney top installation instructions fordetails on how high above the roof top the chimney sections (all pipes) should extend.

Install Top Housing or Termination
Follow the installation instructions provided with thechimney termination you have selected.

Installing Chimney in a Chase
Refer to Page 5, Figure 3 for an illustration of a typicalchase installation.
CAUTION: Use of firestop spacers and construction ofa chase may vary with type of building. These instructions are not a substitute for local building codes. You
must check your local building codes to determine specific requirements for your city or state. NOTE: Other
building materials may be required in addition to MHSC
Firestop Spacers.

Use the same procedure detailed to locate the center
point of the flue system.
Drive a nail up through the roof at the center point. This
will indicate the center point on the outside of the roof
surface.

Installing Gravity Vent
A gravity vent may be installed to supply additional heatto the room the fireplace is in or to adjacent rooms. Figures 22, 23 and 24 show the necessary components forgravity vent ductwork. These parts must be fabricatedor supplied by your fireplace dealer.
CAUTION: Two (2) flex ducts must be installed.
1. 1” (25 mm) minimum air space must be maintained
around the flex ducts.
2. If the flex ducts are going to be stretched beyond
their shipped length, cut the insulation in the middle
and use half at the unit end and the other half at theduct outlet end.
3. The flex ducts may also be vented to adjacentrooms.

1. Remove knockout from outer top of fireplace.
2. Remove the circular cutout from the white insulation
under the outer top.
3. Remove the two (2) screws holding each of thecover plates onto the top heat shield below the white
insulation. Remove the cover plates.
4. Insert the flex pipe collar down through the hole in
the outer top, tab end first.
5. Reach down through the flex pipe collar and bend
the three (3) tabs to hold the collar in place above
the top heat shield.
6. Select the flex duct location. The flex ducts canvent through the side of the chase, through its front,
or one each through both the side and the front.
Either or both flex ducts may also be vented into aroom behind, beside or above the room in which thefireplace is installed. The flex ducts must be installedat least 12” (305 mm) from the ceiling and no lower
than 24” (610 mm) above the top of the fireplace.
Figures 25 and 26 show construction dimensions forsome of the common flex duct placements.
7. Install the flex duct. Before installing the flex ductbox assemblies, you may wish to paint the innersurfaces with high temperature stove paint to reduce
the glare from reflected light.
Install the two duct box assemblies in their framed
openings. (Fig. 27)
If desired, paint the inner surface of each flex duct for
about 6” (152 mm) to eliminate reflected glare; attach
this end to the flange of the duct box assembly.
Cut the tubing a few inches too long with a serrated
kitchen knife - it can be compressed during installation.
The flex duct must fit onto both collars of the duct box
assemblies and the full length of the 2” (51 mm)-all theway around the collars.
Secure each end of the flex ducting to the appropriate collar with sheet metal screws provided. Holes forthe screws must be drilled first around the perimeter
through both the flex duct tubing and the flange with an
1/8” (3 mm) bit. Space the holes as evenly as possiblearound the collar.

for starting, maintaining, and reviving the fire.
Generally, more air entering the fireplace makes the fireburn hotter and faster, while less air prolongs the burn.

Burn Only High-Quality Wood
The Stratton is designed to burn natural wood only; do
not burn other fuels.
You will enjoy the best results when burning wood thathas been adequately air-dried. Avoid burning “green”
wood that has not been properly seasoned.
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.

Another option for getting more combustion air to thefireplace is to duct air directly from the outside to thefireplace. In fact, in some areas provisions for outside
combustion air are required in all new construction.

KT108cIncorrect

Fig. 37 Correct door position during operation.

For areas that do not have a supply of hardwood, commonly burned softwoods include tamarack, yellow pine,
white pine, Eastern red cedar, fir, and redwood. These
too should be properly dried. Your Stratton will accept
wood up to 20” (508 mm) in the front and 18” (457 mm)in the back. Longer wood pieces work better than shortones.
KT108bCorrect
Wood should be stored
under door
cover position
to maintain dryness, and should be 6/08
dried at least one year for optimum
heating and fire-viewing performance. Even for shortterm storage, however, keep wood a safe distance fromthe heater and keep it out of areas around the heaterused for refueling and ash removal.
Use the Air Control Settings
that Work Best for You
No single air control setting will fit every situation. Eachinstallation will differ depending on the quality of thefuel, the amount of heat desired, and how long you wish
the fire to burn.
The control setting also depends on your particularinstallation’s “draft,” or the force that moves air fromthe fireplace up through the chimney. Draft is affectedby such things as the length, type, and location of thechimney, local geography, nearby obstructions, andother factors.
Too much draft may cause excessive temperaturesin the fireplace. On the other hand, too little draft cancause 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 glowing internal parts of the Stratton. A
sign of inadequate draft is smoke leaking into the room
through the fireplace or chimney connector joints, lowheat, and dirty 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 fireplace on the windward side of the house will
provide the fresh air needed.

30004508

Your Stratton is designed to incorporate outside airfor combustion. Directions for installing the optional
AK-MST outside air duct are included with the kit andbeginning on Page 11 of this instruction.
When first using the fireplace, keep track of the settingsof the air controls. You will quickly find that a specificsetting will give you a fixed amount of heat. It may takea week or two to determine the amount of heat and thelength of burn you should expect from various settings.
Most installations do not require a large amount of
combustion air, especially if adequate draft is available.
Do not for any reason attempt to increase the firingof your heater by altering the air control adjustment
range outlined in these directions.

Starting and Maintaining a Wood Fire
Burn solid wood fuel only in the Stratton, and burnit directly on the hearth. Do not elevate the fuel. Do
not burn coal or other fuels.
Minimize thermal stress by allowing the plates to adjust
gradually during an initial break-in fire by following
Steps 1-3 below.
WARNING: Operate your Stratton only with thedoor fully closed. If the door is left partially open,
gas and flame may be drawn out of the fireplace
opening, creating risks of both fire and smoke.
Follow these guidelines as you start and maintain thefire, and remove the ashes. Prior to starting a fire witha cold fireplace, it is recommended to clear the lower
primary air holes located under the front brick. To dothis, remove the andiron and lift out the front refractory
brick. Sweep any ash accumulation out of the three (3)air slots. Keeping these slots clear of ash will ensure
better performance.
1. Open the primary air control fully.
2. Lay some crumpled newspapers in the bottom.
Place on the paper six or eight pieces of dry, finelysplit kindling. On the kindling lay two or three larger
sticks of split dry wood approximately 1-2” (25-50
mm).
Do not use chemicals or fluids to start the fire. Do
not burn garbage or flammable fluids such as gasoline, naptha, or engine oil. Also, never use gasoline-type lantern fuel, kerosene, charcoal lighter
fluid, or similar liquids to start or “freshen up” a firein this heater. Keep all such liquids well away fromthe heater while it is in use.
3. Light the newspaper and close the door. Graduallybuild up the fire by adding a few 3-5” (76 -127 mm)diameter splits.
21Vermont Castings Stratton
If this is your initial break-in fire, let the fire burn brightly,
but not to excess. Control the fire’s intensity by adjusting the air control lever. After an hour or so stop adding
wood so that the fire dies out gradually.
For ongoing operation after the initial break-in, continue
to add a few sticks at a time of a progressively larger
size. Be sure to keep the fuel load behind the front
grate bar at all times. Continue until you have a live
ember bed at least 3-4” (76 - 102 mm) deep. This may
take an hour or longer, particularly when the Stratton
is vented to an exterior chimney or when the system isvery cold.
You’ll soon find that the insert is HOT WHILE IN OPERATION! KEEP CHILDREN, CLOTHING, AND FURNITURE AWAY. CONTACT MAY CAUSE SKIN BURNS.
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 should heat the chimney enough to initiate
a draft.
Once the draft is established, open the front door andlight the rest of the fuel from the bottom. Do not light themain bed of fuel until the chimney begins drawing, andrepeat the procedure as often as necessary if the initialattempt is unsuccessful.
4. Once a good ember bed of at least 3-4” (76 - 102mm) has formed, add the desired amount of woodand close the primary air control to a medium-low
setting. The fire volume will diminish immediately,
but the Stratton will continue to heat up. Maintaincontrol of the fire using the primary air control, andremember: reduce the setting for less heat, increase
the setting for more heat. Refer to the air control settings chart on Page 18 for recommended settings at
different burn rates.
CAUTION: When loading the Stratton, open thedoor slowly to prevent flame from rolling out of thefront of the unit.
Do not over-fire this heater.
Overfiring may cause a house fire, or can result inpermanent damage to the fireplace. If an exterior
part of the Stratton glows, you are overfiring.

Reloading and Reviving a Wood Fire
Set the air control on “High,” and wait at least fifteen
seconds for the draft to increase. Turn the convection
blower off. Open the door slowly.
IMPORTANT: While the stove is hot, toss and sift
the coals with each stove loading. This loosens andhelps burn coals that become buried in the ash.
Push coals away from the three bottom air jets. Creating this “void” helps maintain a reliable fire.
22

Check the ash level, and remove excess ash. Three(3) primary air holes located under the front brickprovide air to the coal bed. (Fig. 38) These holes
should be cleared of ash for proper performance.
Add the fuel, smaller pieces first. If it is necessary to
use wood smaller than the 18” (460 mm) optimum size,
be sure to fill the firebox as completely as possible byloading the wood pieces alternately on the left and right.
Split wood will fill the firebox more completely and reduce the frequency of reloading. If possible, stack wood
diagonally to maximize air spaces between fired pieces.
If you have an ember bed of at least 2-3” (51 - 76 mm),the air setting may not need to be adjusted. If the ember bed is less than 2-3” (51 - 76 mm), you may haveto leave the air setting on high for a few minutes until
flames appear.

Special Tactics for Cold-Climate Heating
The Stratton is capable of producing up to 40,000 BTU/
hour and heating an area of up to 1,500 sq. ft. However, many factors affect heating performance and can
influence the extent to which the Stratton Medium Insert
can heat a given area.
A well-insulated home, located in a moderate climate
and with the Stratton located centrally in an open floorplan, will be easier to heat than a drafty home in the far
north in which a Stratton is installed on an exterior wallat the end of a long house.
Different results may be experienced even in the same
installation if you switch from burning good, dry wood to30004508

Vermont Castings Stratton
wood that is partially rotted or inadequately seasoned.
To compensate for these factors in cold climates, it may
be necessary to operate the for longer periods of timewith the air control set to a higher level more of thetime.

Remove and Store Ash Safely
Check the ash level before reloading the stove, remove
ashes if necessary. Turn off the fan before shoveling theash into your ash container.
Remove ash regularly, typically every one to three days.
The frequency will vary depending on how you operate
your Stratton; more wood is consumed at higher heat
output settings, and ash will accumulate faster.
Ash should be removed frequently and placed outdoors
in a metal container with a tight-fitting lid. The closed
container of ash should be placed on a non-combustible
floor or on the ground, well away from all combustible
materials, pending final disposal. If the ash is disposed ofby burial in soil or otherwise locally dispersed, it should
be retained in the closed container until all cinders havethoroughly cooled. Wood ash may be used as a garden
fertilizer.
CAUTION: Never use your household or shop vacuum
cleaner to remove ash from the fireplace; always remove
and dispose of the ash properly.

How to Replace Gaskets
Your Stratton uses rope-type fiberglass gaskets to makea tight seal between some parts. With use, particularlyon those parts that move, gaskets can become brittle
and compressed and can begin to lose their effectiveness. These will need periodic replacement.
All of the gaskets used are made of fiberglass. The
three sizes of replaceable gasket are listed below, alongwith their application.

Vermont Castings Stratton
The Chimney System
A Clean Chimney System is Saferand Works Better
Although the non-catalytic combustion system in yourStratton can reduce creosote formation dramatically, it
is not a substitute for regular inspection and cleaning of
the chimney and chimney connector.

Learn to Recognize —And Avoid — Creosote
Your Stratton has been designed to minimize creosotebuild-up. Regular chimney inspection and maintenance,
however, must still be performed. For safety, good stove
performance, and to protect your chimney and chimney
connector, inspect your chimney and chimney connector on a regular schedule. Clean the system if necessary. Failure to keep the chimney and connector systemclean can result in a serious chimney fire.
When wood is burned slowly, it produces tar, organic
vapors and moisture which 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 theflue system that can damage the chimney and overheat
adjacent combustible material. If a significant layer ofcreosote has accumulated —1/8” (3 mm) or more — itshould be removed to reduce the risk of a chimney fire.
If you do experience a chimney fire, act promptly to:• Close the primary air control lever (pulled out
fully).
• Get everyone out of the house.
• Call the Fire Department from a nearby house.
You should inspect the system every two months during
the heating season as part of a regular maintenanceschedule. To inspect the chimney, let the Stratton coolcompletely. Then, using a strong light, sight up throughthe flue collar into the chimney flue. The fiber baffle willneed to be removed gently to view inside the connector
pipe.
If it is necessary to remove the firechamber to inspect
or clean the chimney, this is how to do it:• Let the Stratton cool.
• Disconnect the fan power cord (if used).
• You may wish to lighten the firebox by removing
the load door and andiron.
• Retract the two levelling screws until they bear noweight.
• Remove the front air tube and fiber baffle.
• Disconnect the flue collar or vent connector fromthe top of the stove.
26•

Slide the firechamber forward until you have access to the fireplace opening.
• Inspect the flue.
You can now inspect the smoke shelf area of the fireplace and the chimney. Before replacing the Stratton,
this area should be inspected for signs of deteriorationand cleaned thoroughly with a chimney brush.
Clean the chimney using a specially designed brush thesame size and shape as the flue liner. Flexible fiberglass rods are used to run the brush up and down theliner, causing any deposits to fall to the bottom of thechimney where they can be removed through the cleanout door.
The chimney connector should be cleaned 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 individual sections with sheet metalscrews.
If you can’t do the chimney inspection yourself, contact your local Vermont Castings’ Authorized Dealer, or
engage a professional chimney sweep to perform theinspection and cleaning of the chimney.
Reverse the procedure to re-install the firechamber.

Fireplace System Maintenance Schedule
Fireplace:
Daily:• Ash should be removed before the level reaches

the top edge of the front brick. Check each time
you re-load, or at least once a day.
• Keep the area around the fireplace clear of any
combustible material.
Yearly Spring Cleaning:• Remove ash from the firebox and replace with a•moisture-absorbing material (such as kitty litter)to keep the interior of the stove dry.
Touch up painted surfaces with black paint.

Flex Connection:
Two Months:• Inspect the chimney and flue connection. Clean

the system if necessary.
Yearly Spring Cleaning:• Inspect the chimney for signs of deterioration.
Replace damaged sections of prefabricatedchimney. Your local Vermont Castings’ dealer
or a chimney sweep can help determine whenreplacement is necessary.
• Thoroughly clean the chimney.
