Rules For Safe Installation And Operation
Read these rules and the instructions carefully. Failure to follow them will cause a hazard that
could result in death, serious bodily injury, and/or property damage.
Your Furnace is designed to be installed in a parallel air flow arrangement with a gas or oil-fired forced air
upflow-type central furnace, or it may be installed as a central furnace.
1. Check your local codes. The installation must comply
with their rulings.
2. Do not install this furnace in a mobile home or trailer.
3. Always connect this furnace to a chimney and vent to
the outside. Never vent to another room or inside a
building.
4. Do not connect this furnace to an aluminum Type B gas
vent. This is not safe and is prohibited by the National
Fire ProtectionAssociation Code. This furnace requires
a masonry or Listed Factory Built Chimney for residential
type or Building Heating Appliance Chimney. Use a 6"
diameter chimney or larger, that is high enough to give
a good draft.
5. Be sure that if a masonry chimney is used, it is safely
constructed and in good repair. Have the chimney
inspected by the Fire Department or an inspector.
6. Inspect chimney connector and chimney before and
frequently during the heating season for any deposit
of creosote or soot which must be removed.
7. Provide air for combustion into the room where the fur-
nace is located. If the intake is not in the same room,
air must have free access to the room.
8. CAST IRON PARTS MUSTBE "SEASONED" TOAVOID
CRACKING, BUILD ONLY SMALL FIRES ON FIRST
USE.
9. To prevent injury, do not allow anyone to use this fur-
nace who is unfamiliar with the correct operation of the
furnace.
10. For further information on using your furnace safely,
obtain a copy of the National Fire ProtectionAssociation
(NFPA) publication "Chimney's, Fireplaces and Solid
Fuel Burning Appliances" NFPA 211. The address of
the NFPA is Batterymarch Park, Quincy, MA 02269.
11. Keep the ashpit section free of excess ashes. Do not
allow ashes to stack higher than the sides of the ash
pan.
12. 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 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 thoroughly
cooled. Other waste shall not be placed in this container.
13. CAUTION- The special paints used on your furnace
may give off some smoke while they are curing dur-
ing first few fires., Build small fires at first. The metal
used in construction of the furnace and duct work has
a light coating of oil. This could give off smoke and/or
odor from registers when furnace is used for the first
time. This should disappear after a short period of time.
Once this burn-off has occurred, it should not reoccur.
14. CARING FOR PAINTED PARTS- This furnace has a
painted outside jacket, which is durable, but it will not
stand rough handling or abuse. When installing your
furnace, use care in handling. Clean with soap and
warm water when furnace in not hot. DO NOT use
any acids or scouring soap, as these wear and dull
the finish. DISCOLORATION WILL OCCUR IF THE
FURNACE IS OVERHEATED. FOLLOW OPERATING
INSTRUCTIONS CAREFULLY.
15. Keep the feed and ash doors closed at all times except
while tending the furnace.
16. WARNING: RISK OF FIRE - Inspect and clean flues
and chimney regularly
CAUTION: Hot surfaces
CAUTION: Keep children away
CAUTION: Do not touch during operation
CAUTION: Maximum draft marked on nameplate
CAUTION
GASES THAT ARE DRIVEN FROM FRESH COAL
MUST BE BURNED OR THEY WILL ACCUMULATE
AND EXPLODE. NEVER SMOTHER A FIRE WHEN
ADDING FRESH COAL.
CAUTION
DO NOT OPERATE WITH THE FEED AND/OR ASH
DOOR OPEN. THIS FURNACE IS DESIGNED FOR
THERMOSTATIC OPERATION. OPERATION WITH
ANY OF THESE DOORS OPEN WILL OVERHEAT AND
DAMAGE THE FURNACE.
CAUTION
NEVER USE GASOLINE, GASOLINE-TYPE LANTERN
FUEL, KEROSENE, CHARCOAL LIGHTER FLUID, OR
FLAMMABLE LIQUIDS TO START OR "FRESHEN UP"
A FIRE IN THE FURNACE.
WARNING
NEVER STORE FLAMMABLE LIQUIDS, ESPECIALLY
GASOLINE, IN THE VICINITY OF THE FURNACE.

5
Your furnace is designed to be a supplemental or central
heating source for your home. This Solid Fuel Furnace
may be installed in conjunction with a properly operating
central furnace that is listed or certified in accordance with
nationally recognized safety standards and equipped with
the required controls and other safety features and which
has been installed in accordance with appropriate standards
of the National Fire Protection Association with installation
clearances specified in the furnace nameplate marking. The
installation must be accomplished by a qualified agency
(one who is engaged in, and is responsible for, or is thor-
oughly familiar with the installation and operation of the
gas, oil, and solid fuel burning heating appliances, who is
experienced in such work, familiar with all the requirements
of the authority having jurisdiction.) The installation shall
be in strict accordance with the manufacturer's installation
instructions furnished with the solid fuel furnace.
The chimney connector of the furnace is to be installed to
provide clearances to combustible material not less than
specified in the individual classifications and marked on the
furnace. The chimney connector must be connected to a
chimney suitable for use with residential type or building
heating appliances which burn solid fuel.
The Furnace is designed to operate in either parallel or
series air flow arrangement with the central furnace or as
a central furnace.
CENTRAL FURNACE
INSTALLATION
As a central furnace, the unit functions independently of any
other system. The blower will come on when the plenum
temperature reaches the setting on the blower control.
PARALLEL INSTALLATION
(U.S. ONLY)
The design is such that when the blower comes on, the
blower on the central system also comes on. The blower
will only come on when the temperature in the plenum has
reached the setting on the blower control. This is to insure
that there is sufficient warm air in the system to make it
efficient for the unit to operate. When the central system
thermostat calls for heat, the central system will operate
by the burner igniting and the blower coming on. It is pos-
sible that both systems will operate simultaneously. It is
recommended that for the most efficient use of your furnace,
that it be fired as much as possible in order to reduce the
demand on your existing central heating system. This unit
has an optional forced draft kit that operates from a wall
thermostat. When the temperature falls below the setting
on the wall thermostat, the forced draft will come on (U.S.
Stove Option 11/DIKL)
The warm air supply outlet of the furnace shall not be con-
nected to the cold air return of the central furnace, because
the possibility exists of components of the central furnace
overheating and causing the central furnace to operate
other than is intended.
SERIES INSTALLATION
This type of installation uses only the blowers of the existing
central furnace. The solid fuel fan/limit control must also
control the functions of the existing furnace. All electrical
power must come from a single branch circuit.

Locating The Furnace
1. The furnace should be located in the same room as the
central system and as close as possible, but not closer
than 9". There should be no wall between the furnace
and the warm air outlet duct that is connected directly
to the warm air outlet plenum of the central furnace.
(See Fig. 4)
2. Place the furnace on a noncombustible floor.
3. Check figures 3 through 5. Be sure you have the clear-
ances shown below from the furnace and the connector
pipe to combustible surfaces. If you have a solid brick
or stone wall behind your furnace, you can place the
furnace as close as you wish to the wall. If the wall is
only faced with brick or stone, treat it as a combustible
wall.

Chimney Connection
MASONRY CHIMNEY
Before using an existing masonry chimney, clean the chimney
and inspect the flue liner to be sure it is safe to use. Make repairs
before attaching the furnace. The connector pipe and fittings you
will need to connect directly to a masonry chimney are shown.
The chimney connection should be as short as possible.
If the connector pipe must go through a combustible wall be-
fore entering the masonry chimney, consult a qualified mason
or chimney dealer. The installation must conform to local fire
codes, and N.F.P.A. 211.
DO NOT CONNECT THIS FURNACE TO A CHIMNEY
FLUE SERVING ANOTHER APPLIANCE.
The chimney used for a furnace must not be used to ventilate the
cellar or basement. If there is a cleanout opening at the base of
the chimney, close it tightly.
LISTED FACTORY BUILT CHIMNEY
Carefully follow chimney manufacturer's instructions. Use only a
Listed Residential Type or Building Heating Appliance Chimney.
If your chimney starts at the ceiling (Fig. 7), you will need enough
6" pipe to reach the ceiling.
The top of the chimney must be at least 3 feet above the roof
and be at least 2 feet higher than any point of the roof within 10
feet (Fig. 7).
IMPORTANCE OF PROPER DRAFT
Draft is the force which moves air from the appliance up through
the chimney. The amount of draft in your chimney depends on the
length of the chimney, local geography, nearby obstructions and
other factors. Too much draft may cause excessive temperatures
in the appliance and may damage. Inadequate draft may cause
backpuffing into the room and ‘plugging’ of the chimney.
“Inadequate draft will cause the appliance to leak smoke into the
room through appliance and chimney connector joints.”
“An uncontrollable burn or excessive temperature indicates
excessive draft.”
Take into account the chimney’s location to insure it is not too
close to neighbors or in a valley which may cause unhealthy or
nuisance conditions.

1. The crimped end of the chimney connector fits inside the furnace
flue collar. Install additional chimney connectors and elbow
with the CRIMPED END TOWARD THE FURNACE. This will
allow any condensation in the flue to run back into the furnace.
Use 6" dia. steel pipe and elbows for connection to chimney.
Never use less than 24 gauge and although blued steel is
satisfactory, high temp painted black is much more desirable.
(See Figure 8)
2. Slope any horizontal pipe upward toward the chimney at least
1/4 inch for each foot of horizontal run.
3. You must have at least 18 inches of clearance between any
horizontal piping and the ceiling.(See Fig. 5)
4. The chimney connector must not extend into the chimney flue.
(See Fig. 9)
5. Seal each chimney connector pipe joint with furnace cement.
Also seal the pipe at the chimney.
6. Use 3 sheet metal screws at each chimney pipe joint to make
the piping rigid.
7. The chimney connector may include a section for a barometric
draft regulator between the furnace and the chimney (Fig. 6,
7, & 10). The barometric draft regulator must be installed in
the same room (same pressure zone) as the furnace.
8. Install the barometric draft regulator strictly in accordance
with the instructions that are provided with the barometric draft
regulator.
9. A solid damper must be used in the chimney connecting pipes
between the flue collar and the chimney. When used in conjunc-
tion with a barometric draft regulator, the solid damper must be
placed between the barometric and the chimney. (See Fig. 6,
7, & 10)
ADJUSTING THE BAROMETRIC DRAFT
REGULATOR
1. Drill a hole in the chimney connector within 18" of the flue collar
below the barometric draft regulator just large enough for the
tube of the manometer.
2. Build a fire after all chimney connections have been made.
3. Use a manometer to measure the draft in the flue.
4. Adjust the Barometric Draft Regulator to obtain a draft of 0.05
- 0.06" W.C. under stable fire conditions.

CONNECTION OF CHIMNEY CONNECTOR TO A MASONRY CHIMNEY
THROUGH A COMBUSTIBLE WALL
Figure 8 shows how to connect the chimney connector of a heater to a masonry chimney through a combustible wall.
There are five allowable ways that a chimney connector can be connected to a masonry chimney by passing through a combustible
wall. NFPA Standard 211 allows the following wall pass-through systems.
Figure 11

11
1. Use a minimum 3-1/2" thick brick masonry wall framed into the combustible wall. A fireclay liner (ASTM C315 or equivalent) having
a 5/8" minimum wall thickness must be used and it must be at least 12" away from any material that could catch fire. The inside
diameter of the fireclay liner shall be sized for the proper snug fit of a 6" diameter chimney connector pipe. The fireclay liner shall
run from the outer surface of the brick wall to, but not beyond, the inner surface of the chimney flue and shall be firmly cemented
in place. See Part A.

4. Use an 8" inside diameter solid insulated listed factory-built chimney length which has 1" or more of solid insulation.
The minimum length of this chimney section shall be 12" and will serve as a pass-through for the 6" diameter chimney
connector. There must be at least a 12" air space between the outer wall of the chimney section and any combustible
materials. The chimney section shall be concentric with and spaced 1" away from the chimney connector by means
of sheet steel support plates on both ends of the chimney section. The opening in the combustible wall shall
be covered and the chimney section supported on both sides with sheet steel supports which are at least 24 gauge
(0.024") in thickness. The sheet steel supports shall be securely fastened to wall surfaces on all sides and shall be
sized to fit and hold the chimney section. Fasteners used to secure chimney sections shall not penetrate chimney
flue liner. See Part D.
5. A listed factory-built wall pass-through system may be purchased and installed according to the instructions pack-
aged with it to provide a safe method of passing the chimney connector through a combustible wall for connection to
a masonry chimney.
Additional requirements pertaining to Figure 8 and the above wall pass-through systems:
1. Insulation material used as part of wall pass-through system shall be of noncombustible material and shall have a
thermal conductivity of 1.0 Btu • in./ft.² • °F (4.88 kg • cal/hr • m² • °C) or less.
2. All clearances and thicknesses are minimums: larger clearances and thickness are acceptable.
3. A chimney thimble, as shown for 3" and 4" above (Parts C and D) shall be for types "3" and 4" connections to facilitate
removal of the chimney connector for cleaning. The chimney thimble shall be of ASTM C315 fireclay with 5/8" minimum
wall thickness, or material or equivalent durability. The inside diameter of the thimble shall be sized for the proper snug
fit of a 6" diameter chimney connector pipe. The thimble shall be installed without damage to the chimney flue. The
thimble shall extend through the chimney wall to, but not beyond, the inner surface of the chimney flue and shall be
permanently cemented in place with high temperature cement.
4. A chimney connector to a masonry chimney, except for 2" above (Part B), shall extend through the wall pass-through
system to the inner face of the chimney flue, but not beyond. It does not have to be fastened in place so long as it
cannot accidently be pulled out of the chimney or shoved into the chimney flue. If fasteners are used to secure the
chimney connector to a masonry chimney, the fasteners shall not penetrate the chimney flue liner.
5. Any material used to close up any opening for the connector shall be noncombustible.
PART E - (Figure 12)
In addition to the methods shown by A, B, C, and D of Figure 12, a listed factory-built wall pass-through system
may be purchased and installed according to the instructions packaged with it to provide a safe method of
passing chimney connector through a combustible wall for a connection to a masonry chimney.
CONNECTION OF CHIMNEY CONNECTOR TO A MASONRY CHIMNEY WHEN CHIMNEY CONNECTOR
DOES NOT PASS THROUGH A COMBUSTIBLE WALL
If the chimney connector does not have to pass through a combustible wall to get to a masonry chimney, simply connect
the chimney connector directly to the masonry chimney's chimney thimble as described and shown by parts C and D of
Figure 12. Remember, the chimney connector should extend into the chimney thimble to the innerface of the chimney
flue but not beyond; if the chimney connector is extended through the chimney thimble into the chimney flue, resistance
to the flow of smoke and gases up the chimney will occur; that flow resistance will have an adverse affect on the opera-
tion and performance of the heater and venting system.

INSTALLATION
Please see all methods of Installation at the rear of
this booklet.
This is a furnace, not a free standing stove. You must direct
heated air from 8" outlets away from the furnace, or it will
not function properly.
1. This installation must be done by a qualified heating
equipment installer.
2. The installation is to be done in compliance with National
Fire Protection Association installation standards: No.
89M, 90B, 211, 70 (National Electrical Code) and Uniform
Mechanical Code 913, 6-4, in the states where applicable.
(Their code offers connecting smoke pipe connectors
into chimney with other fuel burning appliances.)
3. Rooms large in comparison with size of the appliance:
a) Wood or Coal Burning Furnace needs air for combus-
tion and circulation to house.
b) Provision must be made to make up this air and not
starve gas or oil furnace of combustion air.
c) Have the "Authority Having Jurisdiction" determine
that air is of adequate makeup. (Reference N.F.P.A.
Nos. 30&54, Code for Installation of Gas & Oil Equip-
ment).
4. Have the "Authority Having Jurisdiction" to inspect all
chimneys and installations for adequate venting and for
compliance with standard and local codes and regula-
tions regarding installation of wood burning appliances.
5. Installation for Supplemental HeatApplication to Existing
Central System.
a) Place Wood or Coal Burning Furnace so that the
chimney connector will be as short as practical and
avoiding unnecessary sharp turns in the smoke pipe
connector and the installation of devices that would
create excessive resistance to the flow of flue gases.
b) Locate the Wood or Coal Burning Furnace as close as
practical to the existing central hot air heating system,
maintaining clearances as stated on the label on the
fuel door.
c) Clearance from combustible materials must comply
with those stated on the label on the side of the unit.
Refer to the clearance table in the front of this manual.
The installation must be made only on a noncombustible floor.
d) Install the smoke pipe connector to the chimney
with 26-gauge pipe and elbows (to be purchased
separately), maintaining the proper clearances for the
specific model. Seal the smoke pipe in the chimney
with furnace cement. (The chimney connector shall
be securely supported, and joints fastened with sheet
metal screws or rivets.)
e) Install 8" diameter heat pipe to plenum of the central
hot air furnace. Use 26-gauge pipe and connectors (to
be purchased separately). If central air conditioning
is installed in the plenum, install heat pipe above the
air conditioning unit. Secure heat pipe connection
with supports and sheet metal screws.
f) Connect electrical supply in the electrical junction
box that is mounted on the back of the Furnace. See
Wiring Diagram (Fig. 16). Remove the cover from
electrical junction box and connect power supply wires
to wires designated, using wire nuts. The power cord
supplied may be used for installation, if permitted by
local codes and regulations. If the power cord sup-
plied cannot be used, the power supply wiring must
be 90 degrees centigrade in a metal cable and should
be completed by a qualified installer complying with
NFPA Standard No. 70 and local codes.
6) The warm-air supply-duct system be constructed of
metal in accordance with NFPA 90B, 2-1.1
7) The plenums installed to the furnaces shall be con-
structed of metal in accordance with NFPA 90B, 2-1.3
8) If fans are used in the fuel storage area, they must be installed
so as not to create negative pressure in the room where the
solid- fuel burning appliance is located.
9) e maximum combustion air damper setting is "HIGH"
Caution: Do not alter the automatic combustion air damper
for increased ring for any reason.
POWER FAILURE INSTRUCTIONS

OPERATING INSTRUCTIONS
The top down method of fire building is recommended for this
appliance.After making sure that the stove air intake controls
are fully open (completely pull-out towards you), Place the
largest pieces of wood on the bottom, laid in parallel and
close together. Smaller pieces are placed in a second layer,
crossways to the first. A third layer of still smaller pieces is
laid crossways to the second, this time with some spaces
between. Then a fourth layer of loose, small kindling and
twisted newspaper sheets tops off the pile.
Higher efficiencies and lower emissions generally result
when burning air dried seasoned hardwoods, as compared
to softwoods or to green or freshly cut hardwoods.
DO NOT BURN:
1. Garbage;
2. Lawn clippings or yard waste;
3. Materials containing rubber, including tires;
4. Materials containing plastic;
5. Waste petroleum products, paints or paint thinners, or
asphalt products;
6. Materials containing asbestos;
7. Construction or demolition debris;
8. Railroad ties or pressure-treated wood;
9. Manure or animal remains;
10. Salt water driftwood or other previously salt water
saturated materials;
11. Unseasoned wood; or
12. Paper products, cardboard, plywood, or particleboard.
The prohibition against burning these materials does
not prohibit the use of fire starters made from paper,
cardboard, saw dust, wax and similar substances for
the purpose of starting a fire in an affected wood heater.
Burning these materials may result in release of toxic fumes
or render the heater ineffective and cause smoke.
Dead wood lying on the forest floor should be considered
wet, and requires full seasoning time. Standing dead wood
can usually be considered to be about 2/3 seasoned. Split-
ting and stacking wood before it is stored accelerates drying
time. Storing wood on an elevated surface from the ground
and under a cover or covered area from rain or snow also
accelerates drying time. A good indicator if wood is ready to
burn is to check the piece ends. If there are cracks radiating
in all directions from the center then the wood should be dry
enough to burn. If your wood sizzles in the fire, even though
the surface is dry, it may not be fully cured, and should be
seasoned longer
TAMPER WARNING
This wood heater has a manufacturer-set minimum low burn
rate that must not be altered. It is against federal regulations
to alter this setting or otherwise operate this wood heater
in a manner inconsistent with operating instructions in this
manual.
VISIBLE SMOKE
The amount of visible smoke being produced can be an ef-
fective method of determining how efficiently the combustion
process is taking place at the given settings. Visible smoke
consist of unburned fuel and moisture leaving your stove.
Learn to adjust the air settings of your specific unit to pro-
duce the smallest amount of visible smoke. Wood that has
not been seasoned properly and has a high wood moisture
content will produce excess visible smoke and burn poorly.
Use the includedmoisture meter to insure your wood has a
20% or less moisture content.
EFFICIENCIES
Efficiencies can be based on either the lower heating value
(LHV) or the higher heating value (HHV) of the fuel. The
lower heating value is when water leaves the combustion
process as a vapor, in the case of woodstoves the moisture
in the wood being burned leaves the stove as a vapor. The
higher heating value is when water leaves the combustion
process completely condensed. In the case of woodstoves
this would assume the exhaust gases are room temperature
when leaving the system, and therefore calculations using
this heating value consider the heat going up the chimney
as lost energy. Therefore, efficiency calculated using the
lower heating value of wood will be higher than efficiency
calculated using the higher heating value. In the United
States all woodstove efficiencies should be calculated using
the higher heating value.
The best way to achieve optimum efficiencies is to learn the
burn characteristic of you appliance and burn well-seasoned
wood. Higher burn rates are not always the best heating
burn rates; after a good fire is established a lower burn rate
may be a better option for efficient heating. A lower burn
rate slows the flow of usable heat out of the home through
the chimney, and it also consumes less wood.
FLUE
If the flue-draft setting is exceeded it could cause a solid
fuel fire to burn out of control.
FUEL
Egg size (1-3/16" or larger) bituminous coal for residential
furnaces, or any of the specially packed fireplace coals
can be used. Coal with a low ash content (2% to 6%) is
recommended.
Hardwood, 18" to 26" should be split and air dried (sea-
soned) for 6 months.
DO NOT USE CHEMICALS OR FLUIDS TO START THE
FIRE.
DO NOT BURN GARBAGE, GASOLINE, NAPHTHA, EN-
GINE OIL, OR OTHER INAPPROPRIATE MATERIALS.
DO NOT STORE FUEL WITHIN THE APPLIANCE IN-
STALLATION CLEARANCES OR WITHIN THE SPACE
FOR FUELING, ASH REMOVAL, AND OTHER ROUTINE
MAINTENANCE.

17
LIGHTING
1. Set the thermostat on "HIGH" for maximum draft.
2. Open the feed door and place paper and kindling on the
grate for starting the fire.
3. Light the fire and close the feed door.
4. Add wood or about 15 lbs. of coal (depending on which
model) after fire is burning briskly.
5. "MEDIUM" setting is normally satisfactory. Set higher or
lower for your comfort.
ADDING FUEL
When starting a fire, add small amounts of fuel instead of
adding large quantities of fuel. This will give more complete
combustion and less build-up of tars or soot in the chimney.
A small intense fire is preferable to a large smoldering one
to reduce the amount of creosote deposition.
1. Set thermostat to HIGH before opening feed door.
2. Wood fire: Add wood to a convenient level.
3. Coal Fire:
a.) Never smother the fire when adding coal. Gases
from the accumulation smoke will explode under
certain conditions. Add fresh kindling if the bed of
coals has cooled.
b.) Add up to 20 lbs. of coal per loading. Never add
coal above the bottom of feed door opening.
c.) Stir the coal and watch the fire. Be sure the new
coal is burning briskly before you close the doors
and turn the thermostat down.
d.) Shake grates vigorously 1/2" left to right to spill
ashes into the ash pan. Do this at least once every
12 hours of operation. Empty ash pan regularly. Do
not allow ashes to build-up to grate as grate will warp
and burnout, and you might spill the ashes when
removing the pan. Dispose of hot ashes properly.
e.) Rotation of the handle (5 o'clock to 7 o'clock) posi-
tion will agitate coals and spill ashes into ash pan.
f.) It is advisable for you to get familiar with the shaker
grate operation before firing.
OVER FIRING
Attempts to achieve heat output rates that exceed heater
design specifications can result in permanent damage to
the heater.
ASH REMOVAL AND DISPOSAL
Whenever ashes get 3 to 4 inches deep in your firebox or
ash pan, and when the fire has burned down and cooled,
remove excess ashes. Leave an ash bed approximately
1 inch deep on the firebox bottom to help maintain a hot
charcoal bed.
Ashes should be placed in a metal container with a tight-
fitting lid. The closed container of ashes should be placed
on a noncombustible floor or on the ground, away from all
combustible materials, pending final disposal. The ashes
should be retained in the closed container until all cinders
have thoroughly cooled.
SMOKE AND CO MONITORS
Burning wood naturally produces smoke and carbon
monoxide(CO) emissions. CO is a poisonous gas when
exposed to elevated concentrations for extended periods
of time. While the modern combustion systems in heaters
drastically reduce the amount of CO emitted out the chimney,
exposure to the gases in closed or confined areas can be
dangerous. Make sure you stove gaskets and chimney joints
are in good working order and sealing properly to ensure
unintended exposure. It is recommended that you use both
smoke and CO monitors in areas having the potential to
generate CO.
GASKETS
It is recommended that you change the door gasket (which
makes your stove door air tight) once a year, in order to in-
sure good control over the combustion, maximum efficiency
and security. To change the door gasket, simply remove the
damaged one. Carefully clean the available gasket groove,
apply a high temperature silicone sold for this purpose, and
install the new gasket. You may light up your stove again
approximately 24 hours after having completed this opera-
tion. This unit’s feed door uses a 1/2" diameter rope gasket.
This unit’s ash door uses a 5/8" diameter rope gasket.
OPERATIONAL TIPS
Operational Tips for Good, Efficient, and Clean Com-
bustion
• Get the appliance hot and establish a good coal bed
before adjusting to a low burn rate (this may take 30
minutes or more depending on your wood)
• Use smaller pieces of wood during start-up and a
high burn rate to increase the stove temperature
• Be considerate of the environment and only burn
dry wood
• Burn small, intense fires instead of large, slow burn-
ing fires when possible
• Learn your appliance's operating characteristics to
obtain optimum performance
• Burning unseasoned wet wood only hurts your stoves
efficiency and leads to accelerated creosote buildup
in your chimney

18
Adraft reading of .05 to .06 w.c. is suggested for
proper burning of this unit when using wood or
bituminous coal as fuel. When using anthracite
coal, this draft reading is a minimum reading.
SERVICE HINTS
Do not expect a furnace to draw. It is the chimney that
creates the draft. Smoke spillage into the house or
excessive build-up of water or creosote in the chimney
are warnings that the chimney is not functioning prop-
erly. Correct the problem before using furnace. Possible
causes are:
1. The connector pipe may be pushed into the chimney too
far, stopping the draft.
2. Do not connect two furnaces or a stove and furnace into
the same chimney flue.
3. The chimney used for a furnace must not be used to
ventilate the cellar or basement. If there is a cleanout
opening at the base of the chimney, it must be closed
tightly.
4. If the chimney is operating too cool, water will condense
in the chimney and run back into the furnace. Creosote
formation will be rapid and may block the chimney.
Operate the furnace at a high enough fire to keep the
chimney warm, preventing this condensation.
5. If the fire burns well, but sometimes smokes 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 a 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 3 feet above
the roof and be at least 2 feet higher than any point of
the roof wseh tips.
CHIMNEY MAINTENANCE
Creosote and Soot - Formation and Need for Removal
When wood is burned slowly, it produces tar and other or-
ganic vapors, which combine with expelled moisture to form
creosote. The creosote vapors condense in the relatively
cool chimney flue of a slow-burning fire. As a result, creo-
sote residue accumulates on the flue lining. When ignited,
this creosote makes an extremely hot fire.
When coal is burned, the products of combustion combine
with moisture to form a soot residue which accumulates on
the flue lining. When ignited, this soot makes an extremely
hot fire.
The chimney should be inspected at least twice monthly
during the heating season to determine if a creosote or soot
build up has occurred.
If creosote or soot has accumulated, it should be removed
to reduce the risk of a chimney fire.
Chimney fires burn very hot. If the chimney catches fire,
immediately call the fire department, then reduce the fire
by closing the inlet air control. Pour a large quantity of
coarse salt, baking soda or cool ashes on top of the fire in
the firebox.
The following rules should be followed to reduce the risk of
soot or creosote fires:
1. Establish a routine for the storage of fuel, care of the
appliance and firing techniques.
2. Check daily for creosote buildup until experience shows
how often cleaning is necessary.
3. be aware that the hotter the fire, the less creosote is
deposited, and that weekly cleaning can be necessary
in mild weather, even though monthly cleaning can be
enough in the coldest months.
It is necessary to keep the fuel loading and de-ashing doors
closed and maintain all seals in good condition.
CAUTION
A chimney fire may cause ignition
of wall studs or rafters which you
thought were a safe distance from
the chimney. If you have a chimney
fire, have your chimney inspected by
a qualified person before using again.
Solid fuel burning appliances
need to be cleaned frequently
because soot, creosote and ash
may accumulate.
ATTENTION:
This wood heater needs periodic inspection and repair for proper operation. It is against
federal regulations to operate this wood heater in a manner inconsistent with operating
instructions in this manual.

Trouble Shooting Tips for Warm Air Furnace
1. Problem:
Smoke puffs from furnace
Solution:
A. Check chimney draft. Check for blocked chimney or
flue pipe. Use mirror to check chimney clearance.
B. Check ash pit — if it is too full, empty.
C. Make sure furnace room is not too airtight.
D. Make sure all of chimney mortar connections are
airtight.
E. Check ash drawer. Make sure it’s airtight.
F. Check chimney for possible down-draft caused by
taller surrounding trees or objects. Correct with proper
chimney vent cap.
G. Check the possibility of a cold chimney forcing cool
gases backward. Remedied by properly insulating
chimney with non-combustible liner — non-combus-
tible insulation.
H. Fuel may be too green.
I. Make sure no other fuel burning devices are con-
nected to the chimney impairing the draft.
J. Check chimney draft, it should be .06 inches of wa-
ter column. This service is provided by a certified
chimney sweep.
2. Problem:
Inadequate heat being delivered to your home
Solution:
A. Check home insulation — is it adequate?
B. Check hook-up to furnace — is it installed correctly?
C. Cool air inlet may be inadequate or furnace room
too airtight.
D. Your wood fuel may be too low grade. Hardwoods
are recommended.
E. Make sure your hot air duct (and other duct work) is
airtight.
F. If furnace room is warm but your home isn’t, check
back draft dampers.
G. Is air to the blower available?
3. Problem:
Excess smoke or flames coming out door when refueling
Solution:
A. Wait 15 seconds and open door SLOWLY — then
refuel.
B. Check length of flue pipe to chimney. Your unit should
be within six (6) feet of your chimney.
C. Make sure chimney cap is not too close to the top
of the chimney.
D. Check chimney draft — make sure chimney flue pipe
is clean and chimney is of adequate height.
E. Make sure you’re not suffocating the fire with exces-
sive amounts of unburned wood.
F. Slide baffle should be pulled out prior to load door
opening.
4. Problem:
