twice monthly during the heating season and clean
if necessary. (see Service Hints).
12. In the event of a chimney fire, turn the air controls to
closed positions, leave the building and CALL THE
FIRE DEPARTMENT IMMEDIATELY! Have a clearly
understood plan on how to handle a chimney fire by
contacting your local fire authority for information
on proper procedures in the event of a chimney fire.
After the fire is out, the chimney must be cleaned
and inspected for any stress or cracks before starting
another fire. Check the condition of any combustibles
surrounding the chimney.
13. Ashes should not be allowed to accumulate above
the top of the lower primary air orifice (LPAO, air vent
at front of firebox, just inside of door).
14. DISPOSAL OF ASHES
Ashes should be placed in a steel container with
a tight fitting lid and moved outdoors immediately.
The closed container of ashes should be placed
on a noncombustible floor or on the ground, well
away from all combustible materials, pending final
disposal. If the ashes are disposed of by burial in
soil or otherwise locally dispersed, they should be
retained in the closed container until all cinders have
completely cooled. Other waste shall not be placed
in this container.

18. The special paints used on your stove may give
off some smoke and an odor while they are cur-
ing during the first 12 to 15 fires. Additional smoke
and odor may be emitted from the light oils used
in construction of the fire box. This should disap-
pear after a short period of time and not occur
again. Persons with lung conditions or owners of
susceptible domestic pets (such as birds) should take
prudent precautions. Open windows and doors as
needed to clear smoke and/or odor. Paint discolor-
ation will occur if the stove is over fired.
19. This stove has a painted surface which is durable
but it will not stand rough handling or abuse. When
installing your stove, use care in handling.
20. CLEAN STOVE FREQUENTLY as soot, creosote
and ash may accumulate. Clean exterior with soap
and warm water when stove is not hot. Do not use
any acids or scouring soap, as these solvents wear
and dull the finish.
21. ALERT ALL PERSONS TO THE HAZARDS OF
HIGH SURFACE TEMPERATURES while stove is
in operation – especially young children. Keep away
from a hot stove to avoid burns or clothing ignition.
22. NEVER LEAVE SMALL CHILDREN UNSUPER-
VISED WHEN THEY ARE IN THE SAME ROOM
AS THE STOVE. If small children will be in the same
room as the stove during operation, provide a sturdy
barrier to keep them at a safe distance from the stove.
23. Keep stove area clear and free from all combustible
materials, gasoline, engine oil, naphtha and other
flammable vapors and liquids.
24. WHILETENDINGTHE FIRE ALWAYSWEAR PRO-
TECTIVE CLOTHING, fire retardant hearth gloves
and eye protection, to prevent burns.
25. Never operate this stove without ash drawer, ash
clean out or with the door open except when re-
fueling. Such actions can result in very dangerous
operating conditions.
26. DO NOT OVER FIRE THE STOVE. Over firing
will occur if combustion air is uncontrolled as when
feed door is left open during operation. Such actions
can result in very dangerous operating conditions.
While in operation, keep the feed door closed and
secured at all times except while tending the fire
27. When adding fuel be careful not to smother the fire.
Do not build fires against glass and do not load fuel to
a height or in such a manner that it creates a hazard
when opening the door.
28. NEVER LEAVE THE STOVE UNATTENDED with
door open. Always close the door after ignition.
29. DO NOT CONNECT TO OR USE IN CONJUNC-
SAFETY INSTRUCTIONS continued…
TION WITH ANY AIR DISTRIBUTION DUCTWORK
UNLESS SPECIFICALLY APPROVED FOR SUCH
INSTALLATIONS.
30. A WOOD-BURNING STOVE MUST NEVER BE
INSTALLED IN A HALLWAY OR NEAR A STAIR-
CASE, as it may block egress in the event of a fire.
31. DO NOT INSTALL IN A SLEEPING ROOM.
DO NOT INSTALL IN AN ALCOVE OR INSIDE A
FIREPLACE.
32. Install at least one smoke detector on each floor of
your home. Detectors should be located away from
the heating appliance to avoid false alarms. Detectors
should be located close to sleeping areas. Follow
the smoke detectors manufacturer’s placement and
installation instructions. Maintain smoke detector per
manufacturer’s instructions.
33. CARBON MONOXIDE (CO) HAZARD. A buildup of
CO fumes is toxic and can be fatal. Carbon Monoxide
is a colorless, odorless gas produced during combus-
tion of wood, coal, oil, gas and by other fuel burning
appliances. It is important to have a proper draft and
adequate replacement air ventilation so fumes are
drawn out the chimney. Installed as instructed this
stove is designed to be as safe as possible yet it is
recommended to install a CO detector. Follow the
manufacturer’s recommendations for proper instal-
lation and use. It is recommended to be placed at
table-top level (not near the ceiling) to avoid false
alarms. Realize that devices other than a stove (i.e.
motor exhaust) can trigger CO alarms.

1. The tapered end of the connector stovepipe fits into
the stove flue collar.
2. Horizontal pipe runs must slope upwards
towards the chimney at least 1/4” per foot of hori-
zontal run.
3. You must have at least 18 inches of clearance
between any horizontal piping and the ceiling.
4. The pipe cannot extend into the chimney flue (figure

5. Secure pipe/elbow sections with three sheet metal
screws at each joint to make the piping rigid. Screws
may be no more than a maximum of 3˝/76mm apart.
6. It is recommended that no more than two (2) 90
degree bends be used in the stovepipe installa-
tion. The use of more than two 90 degree bends
may decrease the amount of draw and possibly
cause smoke spillage. Where possible, use only
corrugated (nonadjustable) elbows. These provide
a better seal.
7. The connector pipe must not pass through an at-
tic or roof space, closet, or any concealed space,
or floor, ceiling, wall or combustible construction.
(See Chimney Connector Systems & Clearances,
page 11). A UL 103 HT Listed (U.S.) or ULC-S629
(CANADA) chimney must be used from the first
penetration of ceiling or wall to the chimney cap.
Never use single wall connector pipe as a chimney
- a house fire could result.

CHIMNEY CONNECTIONS
The stove must be connected to either a masonry
or manufactured metal chimney built and tested to the
specifications listed on the previous pages.
Chimneys perform two functions:
1). As a means of exhausting smoke and flue gases
which are the result of fuel combustion.
2). The chimney provides “draft” which allows oxy-
gen to be continuously introduced into the
appliance, so that proper combustion is possible.
This stove relies on natural draft to operate.
NOTICE: Always provide a source of fresh air into
the room where the stove is located. Failure to do so
may result in air starvation of other fuel burning ap-
pliances and the possible development of hazardous
conditions, fire or death.
Your stove itself does not create draft. Draft is
provided by the chimney. To achieve proper draft your
chimney must meet the three minimum height require-
ments detailed in figures 7 – 9. A minimum of 0.05
w.c. (measured in water column) is required for proper
drafting to prevent back puffing, smoke spillage, and to
maximize performance. (Gauges to measure draft are
readily available at stove stores and are economical to
rent or purchase.)
Factors such as wind, barometric pressure, trees,
terrain and chimney temperature can have an adverse
effect on the draft. The manufacturer cannot be held
responsible for external factors leading to less than
optimal drafting.
Should you have a problem with inadequate draft,
you should contact a licensed heating and cooling con-
tractor for assistance in solving the problem.
IMPORTANT Installation Points
1. Size chimney flue to stove collar.This stove requires
a 6” diameter flue.
2. Never connect this unit to a chimney serving an-
other appliance.
3. The chimney must meet all minimum height require-
ments.
4. Never use a chimney to ventilate a cellar or base-
ment.
5. Contact your local building authority
for approved methods of installation and any
necessary permits and/or inspections.
MASONRY CHIMNEY
Before using an existing masonry chimney,
clean the chimney, inspect the flue liner and make
any repairs needed to be sure it is safe to use.
Make repairs before attaching the stove. The con-
nector stove pipe and fittings you will need to con-
nect directly to a masonry chimney are shown in

MANUFACTURED CHIMNEY
Refer to chimney and chimney connector maker’s
instructions for installation and use.
Use only 6” diameter listed chimney UL 103 HT
(U.S.) or ULC-S629 (Canada). Chimney made to this
listing is High Temperature rated to 2100 degrees
Fahrenheit. Use chimney from only one manufacturer.
NEVER MIX BRANDS. Carefully follow the chimney
manufacturer’s stated requirements and clearances.
Use the chimney manufacturer’s attic guards, roof sup-
ports, flashing and fire stops when passing through a
ceiling. Use a listed thimble when passing through a
combustible wall. Do not use makeshift compromises
during installation.
WARNING: DO NOT USE A SINGLE-WALL CON-
NECTION PIPE AS A CHIMNEY!
When using a pre-existing chimney, have it’s condi-
tion and installation inspected before using. Make sure
that the chimney meets all of the UL rating requirements
listed above. Be aware that not all manufactured chim-
ney is of the UL 103 HT or ULC-S629 type.
NOTE: It is recommended that you contact a li-
censed heating and cooling contractor (consult your
local yellow pages) for chimney installation.
Manufactured chimney with the proper required UL
listing is available from most home centers, hardware
stores, and HVAC supply stores.
If you have access to the internet, you may wish
to view chimney manufacturers’ information on-line.
See, www.duravent.com, www.selkirkinc.com, or www.
mtlfab.com.
VENTING TO EXISTING FIREPLACE
In some instances, people desire to convert an ex-
isting fireplace for stove use. Usually, safe connection to
an existing masonry chimney requires more work than
using a prefabricated chimney. The existing fireplace
must be closed and sealed at the damper with high-
temperature caulk, ceramic wool, or furnace cement.
Prior to installation, clean and inspect the existing flue
and smoke shelf. Installation should be designed so
the system can be dismantled for periodic cleaning and
inspection. Before conversion, make sure the existing
chimney is structurally sound, the chimney incorporates
a flue liner and make sure it is in good condition. (A flue
liner consists of clay tile that protects the brickwork of
a chimney. If a chimney does not have a liner, or it is
damaged, have it relined by a professional. Do Not use
a chimney that is unlined or damaged!) If you have
any question regarding the condition of the chimney,
consult a qualified licensed contractor, qualified en-
gineer, competent mason, certified Chimney Sweep,

or a knowledgable inspector. Consult your insurance
company if you cannot find a qualified expert.
CAUTION: NOT ALL FIREPLACES ARE SUIT-
ABLE FOR CONVERSION TO ACCOMMODATE
A WOOD STOVE. CHECK WITH A QUALIFIED
EXPERT.
Many prefabricated fireplaces are of the “zero-
clearance fireplace” category. These consist of mul-
tilayered metal construction. They are designed with
enough insulation and/or air cooling on the base, back
and sides so they can be safely installed in direct con-
tact with combustible floors and walls. Although many
prefabricated fireplaces carry endorsements from na-
tionally recognized organizations for use as fireplaces,
they have not been tested for connection to wood stove
heaters. Connecting a stove to such a device will void
the manufacturer’s warranty.
Venting a stove directly into a fireplace does not
meet code and should not be attempted. (This consti-
tutes connection to another appliance - the fireplace.)
The stove warranty will be void with such an installation.
Do not create a hazard in your home by connecting in
this manner.
FIREPLACE INSTALLATION
Directly connecting the stovepipe into the existing
masonry chimney (figure 10 “Type A” Fireplace Conver-
sion) of the fireplace is the only approved method of
installation.This is a complicated and involved process
and to insure safety should only by done by a qualified
installer.
1. An entry hole must be cut through the masonry and
tile liner with minimal damage to the liner. At least 8”
of liner must remain below the entry position.When
3. Secure the thimble with refractory mortar. The
thimble should be surrounded by 12” of solid unit
masonry brickwork or 24” of stone.
4. Install the stovepipe into the thimble as far as pos-
sible without extending past the flue lining (see
figures 4 & 6 on pages 6 & 7).
5. A small airspace (about 1/2”) should remain
between the stovepipe and thimble to allow for
expansion of the pipe. Seal this airspace with high-
temperature caulking or ceramic wool.
6. Secure and seal the damper in the closed posi-
tion using high-temp caulking, ceramic wool, or
furnace cement. Also check to see if the chimney
has a cleanout. If it does, make sure it is closed and
sealed as well. A leaky cleanout will greatly reduce
draft efficiency.

BUILDING A FIRE
1. Open air inlet control fully.
2. Open the feed door and place several wads of
crushed paper in the firebox.
3. Cover the paper with a generous amount of kindling
in a teepee fashion and a few small pieces of wood.
4. Ignite the paper and leave the door open slightly.
DO NOT LEAVE STOVE UNATTENDED WITH
DOOR OPEN!
5. Add large pieces of wood as the fire progresses
being careful not to overload. (Do not fill firebox
beyond firebrick area.) An ideal coal bed of 1 –2”
should be established t achieve optimum perfor-
mance.
6. This unit is designed to function most effectively
when air is allowed to circulate to all areas of the
firebox. An idea; rake a slight (1˝ to 2˝ wide) trough
in the center of the coal bed from front to back prior
to loading the fuel.
7. Once fuel has been loaded, close the door and fully
open air inlet control until fire is well established
(approximately 10 minutes) being careful not to
overfire.

PREVENTING CREOSOTE BUILDUP
1. Burn with air control open for several minutes at
numerous intervals throughout the day during the
heating season, being careful not to over-fire the
unit.
2. Burn stove with air inlet control wide open for sev-
eral minutes every time you apply fresh wood. This
allows wood to achieve the charcoal stage faster
and burns wood vapors which might otherwise be
deposited within the heating system.
3. BURN ONLY SEASONED WOOD. Avoid burning
wet or green wood. Seasoned wood has been dried
for at least one year.
4. A small fire is preferable to a large smoldering one
that can deposit creosote within the heating system.
5. Establish a routine for the handling of fuel, wood
burner and firing technique. Check daily for creo-
sote build-up until experience shows how often you
need to clean for safe operation. Be aware that the
hotter the fire, the less creosote is deposited and
weekly cleanings may be necessary in mild weather
even though monthly cleanings may be enough in
colder months.
WARNING: IN CASE OF CHIMNEY FIRE
(1) CLOSE AIR INLET CONTROL (2) GET OUT
OF THE HOUSE (3) CALL THE FIRE DEPART-
MENT.
8. Re-adjust the air inlet control to desired burn rate.
(If excessive smoke fills the firebox, open air inlet
control slightly until flames resume and wood is
sufficiently ignited.) The basic rule of thumb is
“closed - low,” “half way open - medium” and “fully
open - high.”
ADDING FUEL
Add small amounts of fuel each hour or so instead
of piling large quantities of fuel at one time. This will
insure a more complete combustion process and
less buildup of tars, soot, or creosote will occur in the
chimney.
1. When refueling, adjust air inlet control to the fully
open position. When fire brightens, slowly and
carefully open the door. This procedure will prevent
gases from igniting causing smoke and flame spill-
age.
2. Add fuel being careful not to overload or overfire
the stove.
3. When adding fuel be careful not to smother the
fire. Do not build fires against glass on models with
glass door.
3. Close the feed door and secure tightly.
4. Adjust the air inlet control as described above.
5. Empty ashes regularly. Do not allow ashes
to pile up (see Safety Instructions #14 on
page 2.)
6. Properly dispose of hot ashes (see Safety
Instructions, item #14 on page 2.)
7. Do not overfire the stove.
CAUTION: DO NOT OVERFIRE APPLIANCE.
YOU ARE OVERFIRING IF THE CHIMNEY
CONNECTORS OR STOVE GLOWS RED. CLOSE
THE DOOR AND SHUT DAMPER IMMEDIATELY
TO REDUCE THE AIR SUPPLY TO THE FIRE.
THIS WILL SLOW DOWN THE FIRE.
CAUTION: SLOW BURNING FIRES AND
EXTENDED USE MAY CAUSE EXCESSIVE
CREOSOTE BUILDUP. IGNITION OF CREO-
SOTE BUILDUP OR OVERFIRING MAY CAUSE
A CHIMNEY FIRE. CHIMNEY FIRES BURN
EXTREMELY HOT AND MAY IGNITE
SURROUNDING MATERIALS. IN CASE OF A
CHIMNEY FIRE CALL THE FIRE DEPARTMENT
IMMEDIATELY.
OPERATING TIPS

SERVICE HINTS continued …
CHIMNEY DRAFT
Draft is a function of the chimney, not the
stove — do not expect the stove to draw. Smoke spillage
into the house or excess buildup of condensation or
creosote in the chimney are warnings that the chimney
is NOT functioning properly. Correct the problem before
using the stove. Following are some possible causes
for improper draft.
1. The connector stovepipe may be pushed into the
chimney too far, stopping the draft.
2. If the chimney is operating too cool, water will con-
dense in the chimney and run back into the stove.
Creosote formation will be rapid and may block
the chimney. Operate the stove at a fire level high
enough to keep the chimney warm preventing this
condensation.
3. If the fire burns well but sometimes creates exces-
sive smoke or burns slowly, it may be caused by
the chimney top being lower than another part of
the house or a nearby tree. The wind blowing over
a house or tree, falls on top of the chimney like
water over a dam, beating down the smoke. The
top of the chimney should be at least three (3) feet
above the roof and be at least two (2) feet higher
than any point of the roof within ten (10) feet.
NOTE: A DRAFT READING OF 0.05 TO 0.06
W.C. (WATER COLUMN) IS SUGGESTED FOR
PROPER BURNING OF THIS STOVE.
GLASS CARE
CAUTION: DO NOT OPERATE WITH CRACKED
OR BROKEN GLASS.
Periodic cleaning of glass will be necessary to
prevent accumulations of ash. Acidic ash buildup can
eventually etch and weaken glass. Creosote accumu-
lations should burn off during hot fires. The following
usage and safety tips should be observed:
1. Inspect the glass regularly for cracks and breaks.
If you detect a crack or break, extinguish the fire
immediately and contact the manufacturer for a
replacement before re-firing the stove.
2. Do not slam the door or otherwise impact the glass.
When closing doors, make sure that logs or other
objects do not protrude to impact the glass.
3. Do not build fires against (or that might fall against)
the glass.
4. Do not clean the glass with materials that may
scratch (or otherwise damage) the glass.Scratches
on the glass can develop into cracks or breaks dur-
ing operation.
5. Never attempt to clean the glass while the unit is hot;
allow to dry thoroughly before reuse. If deposits are
not very heavy, normal glass cleaners are adequate
using a soft, non-abrasive cleaning pad.
6. Never put substances which can ignite explosively
in the unit. Even small explosions in confined areas
can blow out the glass.
GLASS REPLACEMENT
WARNING: REPLACE GLASS ONLY WITH 5MM
HIGH TEMPERATURE CERAMIC GLASS OF
THE PROPER SIZE. DO NOT USE SUBSTITUTE
MATERIALS SUCH AS TEMPERED GLASS
OR DOUBLE THICKNESS WINDOW GLASS!
CONTACT THE STOVE MANUFACTURER FOR
REPLACEMENT GLASS.
Gasket and Glass cleaning products are available
at local retail home centers. Manufacturers of cleaning
products include, A.W. Perkins Co. (www.awperkins.
com) or Rutland Products (www.rutland.com).
After extensive use, the gasket material which
provides glass and door seal may lose it’s resiliency
and will need to be replaced. Inspect glass and door
gaskets periodically to ensure proper seal; if gaskets
become frayed or worn, replace immediately.
'LASS2EPLACEMENT0ROCEDURE
1. Ensure appliance is not in operation and is thor-
oughly cooled.
2. Remove screw and glass clips. (See parts list and
diagram.)
3. Remove glass from door frame.
4. If glass is broken, carefully remove and discard
each broken piece to avoid cuts. Discard window
gasket. Replace window and gasket with original
factory replacement parts.
5. Replace new gasket starting at the bottom of glass
working along edges, being sure to center gasket
channel on glass.
6. Trim to length and butt ends together.
7. Perform replacement procedure in reverse order
after replacing glass and gasket.
8. When replacing glass into door, be sure not to
overtighten screws and clips.

CHIMNEY MAINTENANCE
CREOSOTE – FORMATION AND
REMOVAL
When wood is burned slowly, it produces tar and
other organic vapors which combine with expelled mois-
ture to form creosote.The creosote vapors condense in
the relatively cool chimney flue of a slow-burning fire.
As a result, creosote residue accumulates on the flue
lining. If ignited, this creosote creates an extremely hot
fire which may ignite surrounding materials resulting
in a building fire.
The chimney connector and chimney should be
inspected (at least) twice a month during the heating
season to determine if a creosote buildup has occurred.
If creosote has accumulated, it should be removed.
Failure to remove creosote may result in ignition and
may cause a house/building fire. Creosote may be
removed using a chimney brush or other commonly
available materials from your local hardware retailer.
Chimney fires burn very hot. If the unit or chimney
connector should glow red, reduce the fire by clos-
ing the inlet air control and immediately call the fire
department.
CAUTION: A CHIMNEY FIRE MAY CAUSE IGNI-
TION OF WALL STUDS OR RAFTERS WHICH
WERE ASSUMED TO BE A SAFE DISTANCE
FROM THE CHIMNEY. IF A CHIMNEY FIRE
HAS OCCURRED, HAVE YOUR CHIMNEY IN-
SPECTED BY A QUALIFIED EXPERT BEFORE
USING AGAIN.
A fire in the firebox may be smothered by pouring
a large quantity of coarse salt, baking soda, or cool
ashes on top of the fire.
DOOR GASKET REPLACEMENT
CAUTION: DO NOT OPERATE A STOVE THAT
IS MISSING DOOR GASKET MATERIAL. OVER
FIRING AND UNSAFE OPERATING CONDI-
TIONS MAY RESULT.
PROCEDURE:
1. Ensure appliance is not in operation and is thor-
oughly cooled.
2. Remove old door gasket and clean channel.
3. Using an approved, high temperature gasket ce-
ment, apply a thin coat in bottom of channel.
4. Starting at hinge side of door, work gasket into
channel around door unit, end butt and trim to
length.
5. Close door and allow three to four hours for cement
to set before firing appliance.
BLOWER MAINTENANCE
The optional blower is maintenance free other than
cleaning. Lightly vacuum motor and air inlet to keep free
of dust and dirt.

FLOOR PROTECTOR MATERIAL CALCULATIONS
This stove has been tested for and must be installed on a floor protector with the proper Thermal Resistance or
R-value as stated in the installation instructions “Locating Stove” section, step 1, of this manual. If the floor protec-
tor materials listed in the instructions are not available, materials with an equivalent R-value may be substituted.
Alternate materials may be rated with C-factor (Thermal Conductance) or k-factor (Thermal Conductivity)
ratings which must be converted to R-value to determine if the alternate material meets the tested requirements.
The following instructions provide the proper information and formulas for conversion to R-value.
To determine if alternate materials are acceptable follow this sequence.
1. Convert material specifications to R-value:
a. R-value given — no conversion necessary
b. k-factor is given with a required thickness (T) in inches:
R = 1/k x T
c. C-factor is given: R = 1/C
2. Determine the R-value of proposed alternate floor protector:
a. Use formulas in step 1 above to calculate R-value of proposed material(s).
b. For multiple layers, add R-values of each layer to determine overall R-value.
3. If the overall R-value of the floor protector system is equal to or greater than the floor protector specifications given,
the alternate is acceptable.
Definitions:
Thermal conductance (C) = BTU =W
(hr)(ft2)(°F) (m2)(°K)
Thermal conductivity (k) = (Btu)(inch) =W =Btu
(hr)(ft2)(°F) (m)(°K) (hr)(ft)(°F)
Thermal resistance (R) = (ft2)(hr)(°F) =(m2)(°K)
Btu W
Example:
The specs of floor protector material should be 3/4-inch thick material with a k-factor of 0.84.
The proposed alternative material is 4” brick with a C-factor of 1.25 over 1/8-inch mineral board
with a k-factor of 0.29.
Step 1: Convert specs to R-value.
R = 1/k x T = 1/0.84 x 0.75 = 0.893 System must have a R-value of 0.893 = Rspecs
Step 2: Calculate R-value of individual components
4” Brick with C-factor = 1.25. R = 1/C = 1/1.25 = 0.80 = Rbrick
1/8-inch (0.125”) mineral board with k-factor = 0.29. R = 1/0.29 x 0.125 = 0.431 = Rmin.brd.
Step 3: Add R-values of components to get total R-value of system
Rbrick + Rmin.brd = 0.80 + 0.431 = 1.231 = Rsystem
Step 4: Compare Rsystem to Rspecs
Rsystem = 1.231 is larger than Rspecs of 0.893. System R-value exceeds the required
specifications and therefore is an acceptable alternative.
