Installation
safety NOTICE: IF YOUR stove IS NOT PROPERLY INSTALLED, OPERATED AND MAINTAINED, A
HOUSE FIRE MAY RESULT. FOR SAFETY, FOLLOWALL INSTALLATION, OPERATION AND MAINTENANCE DIRECTIONS. CONTACT LOCAL BUILDING
OFFICIALS ABOUT RESTRICTIONS AND INSTALLATION INSPECTION REQUIREMENTS IN YOUR
AREA.
Before you begin an installation, review your plans tobe certain that:• Your stove and chimney connector will be far enoughfrom combustible material to meet all clearance
requirements.
• The floor protector is large enough and is constructed
properly to meet all 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 of
the stove indicates that the Aspen has been tested
to current UL and ULC standards by Intertek Testing
Services of Middleton, Wisconsin. Clearance and installation information is also printed on the label. Local authorities generally will accept the label as evidence that,when the stove is installed according to the informationon the label and in this manual, the installation meetscodes and can be approved. Codes, however, 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 questions about installation, referto the National Fire Protection Association’s publication ANSI/NFPA 211–1988 Standard for Chimneys,
Fireplaces, Vents and Solid Fuel Burning Appliances. In
Canada, the equivalent publication is CSA CAN-B365,
Installation Code for Solid Fuel Burning Appliances andEquipment. These standards are the bases for manynational codes. They are nationally recognized and are
accepted by most local authorities. Your local dealer
or your local building official may have a copy of theseregulations.
Important: Failure to follow these installation
instructions may result in a dangerous situation, including a chimney or house fire. Follow all instructions exactly and do not allow makeshift compromises to endanger property and personal safety.

ChimneysYour stove must be connected either to a soundmasonry chimney that meets local codes, to a relined
masonry chimney that meets local codes, or to an
approved prefabricated metal chimney. Whichever of
those types you use, the chimney and chimney connector must be in good condition and kept clean.
If you use an existing masonry chimney, it must be
inspected to ensure safe condition before the stove isinstalled. Your local professional chimney sweep, building inspector, or fire department official will be able to
make the inspection or direct you to someone 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).
To assure proper draft and good performance, any
chimney used with this stove should extend at least 16’(4.9 m) above the flue collar of the stove.

Masonry Chimneys, cont’d.
• Unused openings in an existing masonry chimneymust be sealed with masonry to the thickness ofthe chimney wall, 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 beforeuse.
• A newly-built masonry chimney must conform to thestandards of local building code, or, in the absenceof a local code, to a recognized national code. Masonry chimneys must be lined, either with code-approved masonry or precast refractory tiles, stainlesssteel pipe, or a code-approved, “poured-in-place”
liner. The chimney clean-out door must seal tightly toensure a good draft.

Prefabricated Chimneys
A prefabricated metal chimney must be one that is tested and listed for use with solid-fuel burning appliances
to the High-Temperature (H.T.) Chimney Standard
UL-103-1985 (2100°F.) for the United States, and High
Temperature (650°C) Standard ULC S-629 for Canada.

Chimney Size
This stove is approved for venting into a masonry chimney with a nominal flue size of 8” x 8” (203 x 203 mm),and into a round flue size of 8” (203 mm) or 6” (152mm).
It 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
in draft, especially if they are located outside the home.
Such large chimneys may need to be insulated or havethe flue relined for proper stove performance.

Do not connect this unit to a chimney flue serving another appliance.
Note: Do not vent this stove into a factory-built(zero-clearance) fireplace. This stove has notbeen tested and listed for that type of installation. Factory-built fireplaces and their chimneys
are specifically designed as a unit for use as
fireplaces. It may void the listing or be hazardous to adapt them for any other use.
Do not connect the STOVE to any air distribution duct or system.

30000369

Ask your dealer about components available for connecting the stove to a steel chimney liner.

Chimney Connector Guidelines
A chimney connector is the double-wall or single-wallpipe that connects the stove to the chimney. The chimney itself is a masonry or prefabricated structure that
encloses the flue. Chimney connectors are used only
to make the connection from the stove to the chimney.
They are for interior use only.
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,and should be 6” (152mm) in diameter. Do not use
galvanized chimney connector; it cannot withstand thehigh temperatures that can be reached by smoke andexhaust gases, and may release toxic fumes under highheat.
If possible, do not pass
Towardthe chimney connectorstovethrough a combustible wall or ceiling. If
passage through a
combustible wall isunavoidable, refer toFlue gas
the recommendations
directionin the section following on Wall Passthroughs. Do not pass
the connector throughFig. 4 Chimney connector.

12/13/99 djt
space. The whole chimney connector
should be exposed and accessible for inspection and cleaning.
Install the single wall chimney connector not less than18” (457mm) from the ceiling. Keep it as short anddirect as possible, with no more than two 90 degree
turns. If possible, use 45° elbows. Slope horizontal
runs of connectors upward 1/4” per foot (20mm permeter) going from the stove toward the chimney. The
recommended maximum length of a horizontal run is3’ (914mm), and the total length of chimney connector
should be no longer than 8’ (2.5 meters).
In cathedral ceiling installations, extend the prefabricated chimney downward to within 8 feet (2.4m) of thestove.
SAFETY NOTE: Always wear gloves and protective
eyewear when drilling, cutting or joining chimney
connector sections .

Aspen® Woodburning Stove
Double-wall Chimney Connectors
The Aspen is approved for installation in the U.S. andCanada with double-wall chimney connectors that havebeen tested and listed for use with solid-fuel burning
appliances by a recognized testing laboratory.
Follow the instructions for assembling and installing
double-wall connectors provided by the manufacturer ofthe double-wall chimney. To ease assembly and help
assure safety, use chimney components manufactured
by a single source.
NOTE: For installations using double-wall connectors, minimum clearances must conform to thoselisted in the clearance chart on Page 13.

Single-wall Chimney Connectors• Beginning at the flue collar of the stove, assemble•••

the chimney connector. Insert the first crimped end
into the stove’s flue collar, and keep each crimped
end pointing toward the stove. Using the holes in theflue collar as guides, drill 1/8” (3 mm) holes in thebottom of the first section of chimney connector andsecure 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 sheet metal screws. The predrilled 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 installed stove and chimney connector
are correct distances from nearby combustible material.

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

Securing the Single-wall Connector
to a Masonry Chimney
The Aspen may be connected to either a freestanding
masonry chimney or to a fireplace masonry chimney.

Freestanding Installations
If the chimney connector must pass through a combustible wall to reach the chimney, follow the recommendations for Wall Pass-Through construction on pages 7-8.
The opening through the chimney wall to the flue - the“breech” – must be lined with a ceramic or metal
thimble which is securely cemented in place.
A metal pipe section called the “thimble sleeve,” slightly
smaller in diameter than standard connector and thethimbles, will allow 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. Be sure that it does
not extend into the flue passage where it could interferewith the draft.
The thimble sleeve should protrude 1-2” (25-50 mm)
into the room. Use furnace cement and thin gasketing
to seal the sleeve in place in the thimble. Secure thechimney connector to the outer end of the sleeve withsheet metal screws.

Special adapters are available from your local dealer tomake the connection between the prefabricated chimney and the chimney connector. The top of such adapters attach directly to the chimney or to the chimney’s
ceiling support package. The bottom of the adapter issecured to the chimney connector.

Aspen® Woodburning Stove
Connection Above the Fireplace
In this installation, the chimney connector enters thefireplace flue though a thimble located above the fireplace. The liner of the fireplace chimney should extend
at least to the point at which the chimney connector
enters the chimney. Follow all the guidelines for installing a chimney connector into a freestanding masonrychimney, and pay special attention to these additional
points:• Check the stove and chimney connector clearances
to combustible mantel and trim materials. If necessary, use a combination of mantel, trim, and connector heat shields to provide the required clearances.
• Double-check connector clearance to the ceiling.
• The fireplace damper must be closed and sealed toprevent room air from being drawn up the flue which
could reduce performance. However, it must be
possible to reopen the damper to inspect or clean
the chimney.

Floor Protection

Floor Protection Requirements

A tremendous amount of heat radiates from the bottom
plate of your Aspen. The floor area directly under andaround the stove will require protection from radiantheat as well as from stray sparks or embers that may
escape the firebox.

C

A

A

Most installations will require that the bottom heatshield be attached. Only when the stove is placed on acompletely noncombustible surface such as unpainted
concrete over earth may it be used without the heatshield.
Even when the bottom heat shield is installed, you must
provide special protection to the floor beneath. For
installations with the heat shield attached, use a noncombustible floor protector such as 1/4” nonasbestos
mineral board or equivalent, or 24 gauge sheet metal.
The floor protector may be covered with a noncombustible decorative material if desired. Do not obstruct the
space under the heater.

Fig. 14 These dimensions are minimum requirements only.
Use greater dimensions whenever possible.

Protection requirements vary somewhat between the
United States and Canada as follows:
U.S. Installations: The floor protector is required under
the stove and must extend at least 16” from the front of
the stove (B, Fig. 14), and at least 6” from the sides andrear (A, Fig. 14). It must also extend under the chimney
connector and 2” to either side. (C, Fig. 14)
In Canada: A noncombustible floor protector is required
under the heater. The floor protector must extend 18”(457 mm) to the front (B, Fig. 14) and 8” (203 mm) fromthe sides and rear. (A, Fig. 14)

Fireplace Hearth Protection
Do not assume that your fireplace hearth is completely
noncombustible. Many fireplace hearths do not satisfy
the “completely noncombustible” requirement because
the brick or concrete in front of the fireplace opening
is supported by heavy wood framing. Because heatis readily conducted by brick or concrete, it can easily
pass through to the wood. As a result, such fireplacehearths can be a fire hazard and are considered a combustible floor.
For all fireplace installations, follow the floor protection
guidelines described above.
Keep in mind 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

Aspen® Woodburning Stove
Mobile Home Installation
The Aspen is approved for use in manufactured (mobile) homes when installed with the optional Mobile
Home Kit #1898 in accordance with the instructions
provided with that kit and any local codes. This approval applies only in the United States.
In addition to the standard installation requirements
described in this manual, the following guidelines apply
to mobile home installations:
1. The stove must be permanently secured to the floorusing the leg clamps and fasteners provided in thekit.
2. The stove must have a permanent connection to theoutside to supply combustion air.
3. The stove must be grounded to the steel chassis of
the mobile home.
4. A listed chimney system, including roof thimble,
spark arrestor, chimney supports, roof flashing andany other components suitable for use in mobile
homes must be used. The chimney system mustcomply with the standard for Chimneys Factory-Built
Residential Type and Building Heating Appliances
UL 103.
5. The chimney must be attached directly to the stove
and must extend at least 3’ (914mm( above the partof the roof through which it passes. The top of thechimney must extend at least 2’ (610 mm) above thehighest point of any part of the mobile home structure within 10’ (3 m) of the chimney.
6. If the chimney exits the mobile home through a wall ata point 7 feet or less above the ground level on which
the mobile home is located, a guard or other noncombustible enclosure must be fitted at the point of exitand extend up to a height of 7’ (2.1 m). Any openings
in this guard must be smaller than 3/4” (19 mm).
7. Check all local building codes, specifically thoserelated to mobile homes. Other requirements may
be applicable to chimney system removal for transportation of the mobile home.
Warning: Do not install the Aspen in a sleeping
room or hallway.
Caution: The structural integrity of the mobile
home roof, floor, walls and ceiling must be maintained.

10

Clearance to Surrounding
Combustible Materials
When the stove is operating, both the stoveplate andthe chimney connector radiate heat in all directions. A
safe installation requires that adequate clearance bemaintained between the stove and nearby combustible
materials to ensure that those materials do not overheat.
Clearance is the distance between either your stoveor chimney connector, and nearby walls, floors, theceiling, and any other fixed combustible surface. Keepfurnishings and other combustible materials awayfrom the stove as well. In general, a distance of 48”(1219 mm) must be maintained between the stove andmoveable combustible items such as drying clothes,furniture, newspapers, firewood, etc. Keep this area
empty of any combustible material.

Safe Ways to Reduce Clearances
The Aspen clearance requirements, listed anddiagramed on pages 10-11, have been establishedthrough testing to UL and ULC standards to meet most
installation configurations. These involve four basic
variables:• When the stove has no listed heat shield installed.
• When the stove does have a listed heat shield
mounted on it.
• When the wall has no listed heat shield installed.
• When the wall does have a listed heat shield
mounted on it.
In general, the greatest clearance is required when thestove will be positioned with no heat shield near a wallwith no heat shield. The least clearance is required
when both the stove and the wall have heat shields.
Reducing a stove clearance may require installation ofa listed heat shield on the chimney connector as well.
Clearances may be reduced only by means approvedby the regulatory authority, or in accordance with theclearances listed in this manual.
When determining clearance, always measure fromthe top plate of the stove, or, from the chimney connector itself, to the adjacent combustible surface. Do notmeasure from the heat shields of the stove or connector
to the combustible surface.

30000369

Aspen® Woodburning Stove
Wall Shields
Wall shields should be constructed of 24 gauge or
heavier sheet metal, or another noncombustible material such as 1/2” (13mm) insulation board or common
brick “laid on flat,” with the 3¹⁄₂" (90mm) side down.

Aspen® Woodburning Stove

Operation
How the Aspen Works
Combustion control is achieved in the Aspen throughtwo separate air delivery systems.
The primary air control lever, located at the left rearcorner of the stove, controls the amount of incoming primary air for starting, maintaining, and reviving the fire.
More air entering the stove makes the fire burn hotter
and faster, while less air prolongs the burn at a lower
heat level.
For the greatest air supply and maximum heat output(but the shortest burn time), move the lever to thestraight up (12 o’clock) position. For a fire that will last
longer with less heat, move the lever to the right. You
can set the lever anywhere in between the left and rightextremes.
The Aspen features an automatic thermostat to ensure
an even heat output at any manual setting you select.
As the fuel burns, the thermostat reacts to the heat radiating from the stove surface and, consequently, adjusts
the air shutter attached to it . As the fire intensity (andheat output) builds, the thermostat slowly closes the air
shutter, thereby restricting incoming combustion air. As
the fire intensity then wanes (and heat output lessens),
the thermostat responds and gradually opens the air
shutter which allows more combustion air to again
enliven the fire. This ebb and flow action functions
continuously to prolong the burn cycle until the fuelbed
is exhausted.
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 fire. Keep all such liquids well awayfrom the Aspen while it is in use.
Caution: the Aspen will be hot while in operation. Keep children, clothing and furniture away.
Contact may cause skin burns.
DO NOT OVERFIRE THIS HEATER. Overfiring
may cause a house fire, or can result in permanent damage to the stove. If any part of thestove glows, you are overfiring.

30000369

Another separate supply of oxygen is delivered to theupper area of the firebox to support combustion ofgases released from the main fuel bed. This Secondary Air enters the stove through two, unrestricted inlets
and is heated while passing through separate channels
before being delivered through three stainless steel
multi-ported tubes located at the top of the firebox.

Burn Only High-Quality Wood
The Aspen is designed to burn natural
wood only; do not burn any 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 woodshould be no longer than 16” (410 mm) in length, however, you will find that shorter wood lengths ease refueling and promote the most efficient combustion.
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.
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.
Keep wood a safe distance from the heater and keep
it out of the areas around the heater used for refuelingand ash removal.

Use the Air Control Settingthat Works Best for You
No single air control setting will be appropriate for every
situation. Settings will differ depending on the quality of
the fuel, 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 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.
Too much draft may cause excessive temperatures in
the Aspen, and could even damage it. On the other
hand, too little draft can cause backpuffing into theroom 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, and dirty
glass.

17

Aspen® Woodburning Stove
In newer homes that are well-insulated and weathertight, poor draft may result from insufficient air in thehouse. In such cases, a slightly opened window ordoor, near the stove on the windward side of the housewill provide the fresh air needed.
A more effective option for delivering ample combustion
air to the stove is to duct air directly from outdoors to
the stove. In fact, in some areas, provisions for outside
combustion air are required in all new construction. The
optional Aspen Outside Air Adapter #1897 is available
from your dealer.

High

MediumWhen you first begin using the stove, pay attention
to the air control settings. You will quickly find that a
specific setting will give you a fixed amount of heat. It
may take some time to determine the amount of heatand the length of burn you should expect from various
settings.
Do not for any reason attempt to increase the firingof your heater by altering the air control adjustment
range outlined in these directions.

Low

Use the following air control settings as a starting point
to help determine the best settings for your installation.

Before you start using the stove, please read the Appendix on Draft Management starting on page 24 tolearn how the characteristics of your installation willaffect the stove’s performance. You and the stove areparts of a system, and other parts of the system have astrong effect on operation; you may need to vary yourfiring technique to get the performance you want.

Starting and Maintaining a Fire
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 Aspen,
minimize thermal stress by allowing the plates to adjust
gradually during three or four initial break-in fires following Steps 1-3.
Burn solid wood fuel only, and burn it
directly on the grate. Do not elevate thefuel. Do not burn coal or other fuels.
warning: operate this stove only with thedoor fully closed.

18

ST262aFig. 28 Air inlet shutter settings; Low - Medium - High.

The Primary Air Inlet must be fully open when starting a fire or when refueling.
Step 1. Open the primary air control fully.
Step 2. Place several sheetsof crumpled newspaper
ST262
in the stove. Avoid using air
glossyor settings
colored paper, as
inlet
these burn poorly. At the front of the firebox, place
12/15/99
on the paper six or eight piecesof dry djt
kindling split
to a finger-width size, and on the kindling lay two or
three larger sticks of split dry wood approximately
1-2” (25-51 mm) in diameter.
Step 3. Light the newspaper and close the door.
Gradually build up the fire by adding a few 3-5” (80120 mm) diameter splits. If this is one of the first
few “break-in” fires, let the fire burn brightly, andthen let it die out.
•  During the break-in fires, don’t let the stove gethotter than 500°F. (260°C) as measured on an optional stove-top thermometer. Adjust the air control
lever as necessary to control the fire.
•  Some odor from the stove’s hot metal, the paint,
and the cement is normal for the first few fires.
NOTE: Some chimneys need to be “primed,” orwarmed up, before they will draw sufficiently to sustain a fire. To correct this situation, roll up a couple
pieces of newspaper, place them on top of thekindling and toward the back of the stove, light them,and close the door. This should heat the chimney
enough to initiate strong draft.
30000369

Aspen® Woodburning Stove
Once the draft is established, open the front door
and light the rest of the fuel bed at the bottom. Do
not light the main bed of fuel until the chimney begins drawing.
Step 4. After the stove has been broken-in using
Steps 1-3, continue to build the fire gradually. Addlarger wood with a diameter of 3-4” (75-102 mm).
Continue adding split logs of this size to the brisklyburning fire until there is a glowing ember bed atleast 2” (51 mm) deep. A good ember bed is necessary for proper functioning and may take up to anhour to establish.
Step 5. Adjust the thermostatic air control for the desired heat output.

Refuel While the Embers Are Still Hot
Reload the Aspen while it is still hot and there are plenty of glowing embers to re-kindle the fire. Include somesmaller pieces of wood in the new load of fuel to help
the stove return to its operating temperature quickly.
Wear stove gloves, and follow this procedure when you
reload your stove:

Step 1. Open the thermostat lever.
Step 2. Open the door and check the ash level in theash pan. If necessary, dispose of the ashes andreplace the pan.
Step 3. Use a fireplace tool to break up the charcoal
and direct ash through the grate. Pull the charcoal
from the back to the front. This will encourage efficient combustion as the fuel burns from front to rear.
(Fig. 31)
Step 4. Load wood — smaller, split pieces first. Closethe door. Ideal performance will be achieved by operating with the air control set in the maximum (HIGH)
positon for several minutes after refueling. Reset the

Ash Disposal
Remove ash before it reaches the top of the ash pan.
Check the level at least once a day, and before each refueling. Using stove gloves, pull the ash pan out of thestove by its handle. Remove the ash pan and properly
dispose of the ashes. Be sure to keep the pan level during disposal.
Empty the ash pan regularly, typically every one tothree days. The frequency will vary depending on how
you operate your Aspen; if you burn more wood athigher heat output settings, ash will accumulate rapidly.
Dispose of ashes into a metal container with a tight-fitting lid kept outdoors. Put the closed container of ash
on a noncombustible floor or on the ground, well awayfrom all combustible materials, pending final disposal.
If the ash is disposed of by burial in soil or otherwise
locally dispersed, keep it in the closed container until allcinders have thoroughly cooled. 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.

CAUTION: Avoid slamming the stove
door or striking the glass panel. Do
not operate the stove with the glass
panel missing, damaged, or broken. Do
not install substitute materials. See
Maintenance section for replacement
instructions.

Smoke Detectors
The use of smoke detectors throughout the home isstrongly advised, if not required by building codes or insurance regulations. It is a good idea to install a smoke
detector in the living areas and each bedroom.
You may not, however, wish to install a detector in theimmediate vicinity of the stove. Depending on the sensitivity of the unit, the alarm can be set off while you are
tending the fire or emptying the ashes. If you install adetector in the same room, locate it as far away fromthe stove as possible.

MaintenanceLet the fire in the stove go out and allow the stove tocool completely before beginning any maintenanceprocedure.

Glass Replacement
Replace glass only with MHSC part no. 30000362. The
glass panel rests on a cushion provided by three flat
gaskets, and is held in place by two clips. (Fig. 32) The
glass is coated on one side which is slightly colored.
Remove the door from the stove and place it on a
sturdy, level work surface. Use a towel to protect theporcelain enamel finish.

Care of the Cast Iron Surface
An occasional dusting with a dry rag will keep the
painted cast iron of your Aspen looking new.
The stove’s paint can be touched up as needed. First,
clean the areas to be painted with a wire brush. Then,
touch up the stove with high temperature stove paint.
Apply the paint sparingly, and keep in mind that twolight coats of paint are better than a single heavy one.

Care of Porcelain Enamel Finish
Use a dry or slightly damp rag or a 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.

Cleaning the Glass
Most of the carbon deposits on the glass will burn off
during hot fires. However, the ash residue that accumulates on the glass surface should be removed regularly
to prevent etching. Follow this procedure to clean theglass:• Be sure the glass is completely cool.
• Clean the glass with water or a cleaner madeespecially for this purpose. Do not use abrasive
cleaners.
• Rinse the glass thoroughly.
• Dry the glass completely.

1. Remove the Door Manifold. (Two phillips headscrews).
2. Remove the Retainer Clips. (Two phillips headscrews on each clip).
3. Inspect the Gasket. If the window gasket is in goodcondition, you can leave it in place. If you replace it,use only MHSC gaskets (two vertical- PN 30000383;
one horizontal– PN 30000384). Be sure the channel around the window opening is clean, and free of
dust.
Place the three flat gaskets (two vertical, one horizontal) into the panel inset as shown in Figure 32.
4. Install the Glass. Lay the glass on the inner gasket
with the coated side down (toward the outside of thedoor). Tighten the screws snugly, but loose enoughto allow for a little movement of the glass when thestove is in operation. Overtightening can crack theglass immediately or cause it to crack if it is unable
to expand when hot.

Adjust the DoorYour Aspen 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.

The door latch may need adjustment as the gasket
material compresses over time. The latch engagement
may be tightened by removing the shim washers thatare under the Latch Plate. (Fig. 33) Remove only one
pair at a time. When a tight engagement can no longer
be achieved with no shim washers in place, the entire
door gasket should be replaced. Use only MHSC part
no. 700-0910.

The sizes of replaceable gasket are listed below, alongwith their applications.

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 dust
mask.
Step 1. Remove the existing gasket by grasping an
end and pulling firmly.
Step 2. Use a wire brush or a screwdriver to clean
the channel of any remaining cement or bits of gasket.
Remove stubborn deposits of cement with a cold chisel
if necessary.

Step 3. Determine the correct length of the appropriate-sized gasket by laying it out in the channel. Allow an
extra 1-2” (25-51 mm), and mark the spot to be cut.
Step 4. Remove the gasket from the channel, place it
on a wood cutting surface, and cut it at the marked spotwith a utility knife.
Twist the ends slightly to discourage the gasket fromunraveling.

Step 6. Starting at one end, press the gasket into thechannel.

Fig. 33 Remove shim washers to tighten latch engagement.

Ensure a good joint where the gasket meets before
trimming any excess. Do not overlap the gasket ends orleave ends with ragged edges.

The Chimney System

Step 7. Press the gasketed part firmly against its
normal mating surface to seat the gasket evenly in its
channel. Close and latch the door to do this; close thedoor on a piece of waxed paper to keep the cementfrom migrating onto the non-gasketed part, or tap otherparts

Your Aspen is designed to reduce creosote buildup
significantly. However, regular chimney inspection andmaintenance must still be performed. For safety, goodstove performance, and to protect your chimney andST268

Creosote

30000369

Aspen® Woodburning Stove
When wood is burned slowly, it produces tar,organic vapors and moisture that combine to form
creosote. The creosote vapors condense in therelatively cool chimney flue. As a result, creosote
residue accumulates on the flue lining. Whenignited, this creosote makes an extremely hot firewithin the flue system that can damage the chimney
and overheat adjacent combustible material.
If you do have a chimney fire, promptly:•   Close the damper and thermostat lever.
    •   Get everyone out of the house.
    •   Call the Fire Department.
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 mirror and a strong light,
sight up through the 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.
If a significant layer of creosote has accumulated— 1/8” (3 mm) or more — remove it to reduce the riskof a chimney fire.
Clean the chimney using a brush the same size andshape as the flue liner. Flexible fiberglass rods areused 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.
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 theindividual sections with sheet metal screws.

• Check gasketing for wear or compression, and

replace if necessary. A ‘paper test’ will guide you on
this. Close and lock the door or damper on a slip ofpaper and then try to pull the paper out. If the paper
pulls out with little or no resistance, the gasket isn’tsnug enough at that spot. If adjusting the damperor latch doesn’t result in a seal that makes it hard topull the paper out, replace the gasketing.
Check door handle for tightness. Adjust if needed.
Check heat shield screws. Tighten as necessary.
Clean dust from the inner sides of bottom, rear andconnector heat shields.
Remove ashes from the ash pan and replace withmoisture absorbing material (such as cat litter) to
keep the stove interior dry. Close the stove door tokeep cats from using the litter.
Touch up the paint on black stoves.

Clean the Primary Air Outlet
Ash accumulation below the primary air plate will eventually result in sluggish, cool fires. Ash accumulation
should be removed at least yearly as follows:
1. Remove the phillips head screw that retains thePrimary Air Plate. (Fig. 34)
2. Use a screwdriver to pry the plate out of the cemented seams.
3. Remove ash debris from the cavity.
4. Use high-temperature furnace cement to reseal thefront seam and side seams and replace the plate.
Secure with the phillips head screw.

If you cannot inspect or clean the chimney yourself,contact your local Vermont Castings’ Authorized Dealer
or hire a professional chimney sweep.

Draft Management
Your stove is only one part of a system that includes thechimney, the operator, the fuel and the home. The otherparts of the system will affect how well the stove works.
When there is a good match between all the parts, thestove works well.
Wood stove operation depends on natural (unforced)
draft. Natural draft occurs when exhaust gas is hotter(and therefore lighter) than the outdoor air at the topof the chimney. The greater the temperature difference, the stronger the draft. As the hot exhaust gas
rises out of the chimney it generates suction that draws
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
inlets are passive; they regulate how much air can enter
the stove, but they do not move air into it.
The efficiency of a modern woodburning appliance,(in which the amount of air available for combustion isregulated), depends on the chimney to keep exhaustgases warm all the way outdoors. The characteristics
of your chimney - whether it is steel or masonry, interioror exterior, matched or mismatched to the stove collar- determine how quickly it will warm up and how wellit will sustain the optimum temperatures necessary tomaintain strong draft and efficient combustion. Here follows a description of various flue system characteristics
and related effects on stove performance.

Masonry Chimney
Although masonry is the traditional material used forchimney construction, it can have distinct performance
disadvantages when used to vent a controlled-combustion woodstove. Masonry forms an effective ‘heat sink’- that is, it absorbs and holds heat for long periods oftime. The large mass, however, may take a long time tobecome hot enough to sustain a strong draft. The larger
the chimney (in total mass), the longer it will take towarm up. Cold masonry will actually cool exhaust gases
enough to diminish draft strength. This problem is compounded if the chimney is located outside the home or if
the chimney flue has a cross-sectional size larger than
the stove outlet.

Steel Chimney
Most factory-made ‘Class A’ steel chimneys have alayer of insulation around the inner flue. This insulation
keeps the smoke warm and protects the surrounding
structure from the high flue temperatures. Because theinsulation is less dense than masonry, the inner steel
liner warms up more quickly than a masonry chimney.
Although steel chimneys are not as attractive as theirmasonry counterparts, they are very durable and generally outperform masonry.

Inside/Outside Location
Because the chimney’s function is to keep the smoke
warm, it is best to locate it inside the house. This location uses the house as insulation for the flue and allows
some radiant heat release from the flue into the home.
Since an interior chimney does not continuously lose its
heat to the outdoors, it takes less heat from the stove to
get it warm and keep it warm.

Flue Sizing
The flue size for a controlled-combustion applianceshould be based on the cross-sectional volume of thestove flue outlet. In this case, more is definitely notbetter. Hot gases lose heat through expansion; if astove with a six-inch flue collar (28 square inch area)
is vented into a 10” x 10” flue, the gases will expand toover three times their original volume. As gases coolwith expansion, draft strength decreases. If an oversized flue is also outside the house, the heat it absorbs
will be conducted to the outdoor air and the flue willremain relatively cool.
It is common for a masonry flue to be oversized for thestove. Such a chimney can take quite a while to warm
up and the stove performance will likely be disappointing. The best solution to an oversize flue problem isthe installation of an insulated steel chimney liner ofthe same diameter as the appliance flue outlet. The
liner keeps the exhaust gas warm and the result is astronger draft. An uninsulated liner is a second choice- although the liner will keep the exhaust restricted to its
original volume, the air around the liner will require timeand heat energy to warm up.
Check your local codes. You may be required to installa flue liner in any oversize or masonry flue.

30000369

Aspen® Woodburning Stove
Pipe & Chimney Layout
Every bend in the flue will act as a brake on the exhaustas it flows from the firebox to the chimney cap. The
ideal pipe and chimney layout is straight up from thestove through a completely straight chimney. Use thislayout if at all possible as it will promote optimum stove
performance and simplify maintenance.
If the stovepipe must elbow to enter a chimney, locate
the elbow about midway between the stove top andthe chimney thimble. This configuration lets the smoke
speed up before it must turn, keeps some pipe in theroom for heat transfer, and allows long-term flexibility
for installing a different appliance without relocating thethimble.

You can judge the moisture content of wood by its appearance and weight or use a commercially available
moisture meter for an exact measurement. Unseasoned
wood will be a third heavier than dry wood. Also, lookfor cracks (‘checking’) in the ends of the log that result
from contraction as the wood dries. The longer andwider the cracks, the dryer the wood is. Purchase yourfuel from a reputable dealer.

Creosote

There should be no more than eight feet of single-wallstove pipe between the stove and a chimney. Longer
runs can cool the smoke enough to cause draft andcreosote problems. Use double-wall stove pipe forlonger runs.

Creosote is a by-product of low-temperature stove
operations, weak draft or both. It is a tar that results
when unburned gases condense inside the flue system at temperatures below 290°F. Creosote is volatileand can generate chimney fire. All of the installation
characteristics that adversely affect chimney draft also
promote creosote condensation. Consequently, you can
minimize creosote accumulation with an effective chimney design and the use of operational techniques thatencourage good draft and complete combustion.

Single Venting

Backpuffing

Your stove requires a dedicated flue. Do not connect
the stove to a flue used by any other appliance. Chimney draft is a natural form of energy and follows thepath of least resistance. If the stove is vented to a fluethat also serves an open fireplace or another appliance,
the draft will also pull air in through those avenues. The
additional air flow will lower flue temperatures, reducedraft strength and promote creosote development; overall stove performance will suffer. The effect is similar
to that of a vacuum cleaner with a hole in the hose. In
some extreme instances, the other appliance can even
impose a negative draft and result in a dangerous draft
reversal.

Backpuffing is a condition that results when the draft is
too weak to pull flue gases out of the chimney system
as fast as the fire is generating more. Volatile gases
build up within the firebox until reaching a density andtemperature at which they ignite. With this ignition, you
may hear a muffled popping sound and see a bit ofsmoke forced out of the air inlets.

Fuel
Even the best stove installation will not perform well if
poor fuel is used. I available, always use hardwood thathas been air-dried (‘seasoned’) 12-18 months. Softwood burns more rapidly than hardwood and has a highresin content conducive to creosote production. Decayed wood of any type has little heat value and should
not be used.
All unseasoned (‘green’) wood has a high moisture content. Much of its heat value will be used to evaporate
moisture before the wood can burn. This significantly
reduces not only the amount of energy available towarm your home, but also the intensity of the fire andtemperature of the exhaust gas. Incomplete combustionand cool flue temperatures promote creosote formation
and weak draft.

30000369

This condition is most likely to occur in the spring or fallwhen moderate outdoor temperatures and low intensity fires combine to inhibit draft strength. If your stove
backpuffs, open the damper to let the smoke rise to theflue more quickly. Also, open the air inlets to induce a
livelier fire and speed airflow through the stove. Avoid
large loads of firewood at one time. You should always
see lively, dancing flames in the firebox; a lazy, smoky
fire is inefficient and will promote draft problems.

Draft TestingAn easy way to determine whether your chimney draft
is strong enough is to close the stove damper, wait a
few minutes to let the airflow stabilize, and then test
whether you can vary the strength of the fire by swinging the air control open and closed. Results here are
not always instant; you may need to wait a few minutes
for a change in the air control setting to have an effect on the fire. If there is no change, the draft is not
yet strong enough to let you close the damper. You willneed to open it for awhile longer and manage the firewith the air inlet until the draft strengthens. Keep a record of your operational habits and relate them to theireffects on the stove’s function. You will be rewarded
with safe and efficient performance.

Conclusion

Good draft also depends on a sufficient supply of air
to the stove. The chimney cannot pull more air than isavailable. Sluggish draft can be caused by a house thatis tight enough to prevent the ready flow of air to thestove, or by competition between the stove and otherappliances that vent indoor air to the outside; i.e., exhaust fans for range hoods, clothes dryers, bathroom,
etc. If the chimney draws well when all such equipment
is turned off (or sealed, in the case of the fireplaces
and/or other stoves), you simply need to be attentive
in timing the use of the other appliances. If you needto crack a nearby window or door to enable the chimney to pull well, you should install an outside-air intake
to bring combustion air directly to the stove. Consult
your Vermont Castings’ dealer regarding an adapter toattach to the stove to connect an air duct for outdoor
combustion air.

Woodburning is more an art than a science. Art includes technique and since installations, homes andfuel vary, the stove operator must also vary technique,(mostly timing), to achieve satisfying results. Overtime, you will become familiar with the intricacies andnuances of your particular installation and you will beable to identify cause and effect in a variety of seasonal
circumstances.
