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 ow arrangement with a gas or oil-
red forced air upow-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 Protection Association 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
furnace is located. If the intake is not in the same
room, air must have free access to the room.
8. CAST IRON PARTS MUST BE "SEASONED" TO
AVOID CRACKING, BUILD ONLY SMALL FIRES
ON FIRST USE.
9. To prevent injury, do not allow anyone to use this
furnace 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 Protection Asso-
ciation (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 ofAshes –Ashes should be placed in a steel
container with a tight tting lid and moved outdoors
immediately. The closed container of ashes should be
placed on a noncombustible oor or on the ground,
well away from combustible materials, pending nal
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 during
rst few res., Build small res at rst. 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
rst 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 nish. 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 ues
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 EX-
PLODE. NEVER SMOTHER A FIRE WHEN ADDING
FRESH COAL.
CAUTION
DO NOT OPERATE WITH THE FEEDAND/ORASH DOOR
OPEN. THIS FURNACE IS DESIGNED FOR THERMO-
STATIC OPERATION. OPERATION WITHANY 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.

Your furnace is designed to be a supplemental
or central heating source for your home. This
Solid Fuel Furnace may be installed in conjunc-
tion with a properly operating central furnace that
is listed or certied 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 ap-
propriate standards of the National Fire Protection
Association with installation clearances specied
in the furnace nameplate marking. The installa-
tion must be accomplished by a qualied agency
(one who is engaged in, and is responsible for,
or is thoroughly 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 au-
thority 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 specied in the individual
classications and marked on the furnace. The
chimney connector must be connected to a chim-
ney suitable for use with residential type or building
heating appliances which burn solid fuel.
The Furnace is designed to operate in either paral-
lel or series air ow arrangement with the central
furnace or as a central furnace.
CENTRAL FURNACE INSTALLATION:
As a central furnace, the unit functions indepen-
dently of any other system. The blower will come
on when the plenum temperature reaches the
setting on the blower control.
HOW THE FURNACE FUNCTIONS
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 tem-
perature in the plenum has reached the setting
on the blower control. This is to insure that there
is sufcient warm air in the system to make it ef-
cient 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 possible that both systems will
operate simultaneously. It is recommended that
for the most efcient use of your furnace, that it
be red 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 connected 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 oor.
3. Check gures 3 through 5. Be sure you have
the clearances shown below from the furnace
and the connector pipe to combustible sur-
faces. 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 ue liner to be sure
it is safe to use. Make repairs before attaching
the furnace. The connector pipe and ttings
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 combus-
tible wall before entering the masonry chimney,
consult a qualied mason or chimney dealer.
The installation must conform to local re 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 instruc-
tions. 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).

1. The crimped end of the chimney connector ts inside
the furnace ue collar. Install additional chimney con-
nectors and elbow with the CRIMPED END TOWARD
THE FURNACE. This will allow any condensation
in the ue 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 be-
tween any horizontal piping and the ceiling.(See Fig.
5)
4. The chimney connector must not extend into the
chimney ue. (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 ac-
cordance with the instructions that are provided with
the barometric draft regulator.
9. Asolid damper must be used in the chimney connect-
ing pipes between the ue collar and the chimney.
When used in conjunction with a barometric draft
regulator, the solid damper must be placed between
the barometric and the chimney. (See Fig. 6, 7, & 10)
AdjustingtheBarometricDraft Regulator
1. Drill a hole in the chimney connector within 18" of
the ue collar below the barometric draft regulator
just large enough for the tube of the manometer.
2. Build a re after all chimney connections have been
made.
3. Use a manometer to measure the draft in the ue.
4. Adjust the Barometric Draft Regulator to obtain a
draft of 0.05 - 0.06" W.C. under stable re conditions.

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 t and hold the chimney section. Fasteners used to secure chimney sections shall not
penetrate chimney ue liner. See Part D.
5. 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 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 conduc-
tivity 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 reclay with 5/8" minimum wall thickness, or
material or equivalent durability. The inside diameter of the thimble shall be sized for the proper snug t of a 6" diameter chimney
connector pipe. The thimble shall be installed without damage to the chimney ue. The thimble shall extend through the chimney
wall to, but not beyond, the inner surface of the chimney ue 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 ue, 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 ue. If fasteners are used to secure the chimney connector to a masonry chimney,
the fasteners shall not penetrate the chimney ue 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 con-
nector 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
ue but not beyond; if the chimney connector is extended through the chimney thimble into the chimney ue, resistance
to the ow of smoke and gases up the chimney will occur; that ow 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 qualied 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 Electri-
cal 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 appli-
ance:
a) Wood or Coal Burning Furnace needs air for
combustion 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" deter-
mine that air is of adequate makeup. (Reference
N.F.P.A. Nos. 30&54, Code for Installation of Gas
& Oil Equipment).
4. Have the "Authority Having Jurisdiction" to inspect
all chimneys and installations for adequate venting
and for compliance with standard and local codes
and regulations regarding installation of wood burn-
ing appliances.
5. Installation for Supplemental Heat Application 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 ow of ue 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 com-
ply 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 noncombus-
tible oor.
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 specic 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 supplied cannot
be used, the power supply wiring must be 90
degrees centigrade in a metal cable and should
be completed by a qualied 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
constructed 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
roomwherethesolid-fuelburningapplianceislocated.
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
Operation after loss of power:
1. Remove lter if provided
2. Do not expect to keep home at normal tem-
peratures.
3. Do not load fuel above bottom of feed door.

Operating Instructions
FLUE
If the ue-draft setting is exceeded it could cause a solid fuel re to burn out of control.
FUEL
Egg size (1-3/16" or larger) bituminous coal for residential furnaces, or any of the specially packed
replace 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 (seasoned) for 6 months.
DO NOT USE CHEMICALS OR FLUIDS TO START THE FIRE.
DO NOT BURN GARBAGE, GASOLINE, NAPHTHA, ENGINE OIL, OR OTHER INAPPROPRIATE
MATERIALS.
DO NOT STORE FUEL WITHIN THE APPLIANCE INSTALLATION CLEARANCES OR WITHIN THE
SPACE FOR FUELING, ASH REMOVAL, AND OTHER ROUTINE MAINTENANCE.
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 re.
3. Light the re and close the feed door.
4. Add wood or about 15 lbs. of coal (depending on which model) after re is burning briskly.
5. "MEDIUM" setting is normally satisfactory. Set higher or lower for your comfort.
ADDING FUEL
When starting a re, 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 re 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 re: Add wood to a convenient level.
3. Coal Fire:
a.) Never smother the re 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 re. 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) position will agitate coals and spill ashes into
ash pan.
f.) It is advisable for you to get familiar with the shaker grate operation before ring.

Service Hints
Do not expect a furnace to draw. It is the
chimney that creates the draft. Smoke spill-
age into the house or excessive build-up of
water or creosote in the chimney are warn-
ings that the chimney is not functioning
properly. 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 ue.
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.
A draft reading of .05 to .06 w.c. is suggested for proper burning of this unit when us-
ing wood or bituminous coal as fuel. When using anthracite coal, this draft reading is a
minimum reading.
Chimney Maintenance
Creosote and Soot - Formation and Need for Removal
When wood is burned slowly, it produces tar and
other organic vapors, which combine with expelled
moisture to form creosote. The creosote vapors
condense in the relatively cool chimney ue of a
slow-burning re. As a result, creosote residue
accumulates on the ue lining. When ignited, this
creosote makes an extremely hot re.
When coal is burned, the products of combustion
combine with moisture to form a soot residue which
accumulates on the ue lining. When ignited, this
soot makes an extremely hot re.
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 re.
Chimney res burn very hot. If the chimney
catches re, immediately call the re department,
then reduce the re by closing the inlet air control.
Pour a large quantity of coarse salt, baking soda
or cool ashes on top of the re in the rebox.
CAUTION
A chimney re may cause ignition
of wall studs or rafters which you
thought were a safe distance from
the chimney. If you have a chimney
re, have your chimney inspected by
a qualied person before using again.
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 re to keep the chimney warm,
preventing this condensation.
5. If the re 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 within 10 feet.
6. See page 18 for list of trouble shooting tips.
Solid fuel burning appliances
need to be cleaned frequently
because soot, creosote and ash
may accumulate.
The following rules should be followed to reduce
the risk of soot or creosote res:
1. Establish a routine for the storage of fuel, care
of the appliance and ring techniques.
2. Check daily for creosote buildup until experi-
ence shows how often cleaning is necessary.
3. be aware that the hotter the re, the less
creosote is deposited, and that weekly clean-
ing 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.

Trouble Shooting Tips for Warm Air Furnace
1. Problem:
Smoke puffs from furnace
Solution:
A. Check chimney draft. Check for blocked chimney or
ue 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 insulat-
ing chimney with non-combustible liner — non-
combustible 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
water column. This service is provided by a certi-
ed 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 ames coming out door when refuel-
ing
Solution:
A. Wait 15 seconds and open door SLOWLY — then
refuel.
B. Check length of ue 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 ue
pipe is clean and chimney is of adequate height.
E. Make sure you’re not suffocating the re with exces-
sive amounts of unburned wood.
F. Slide bafe should be pulled out prior to load door
opening.
4. Problem:
Distribution blower vibrating
Solution:
A. Tighten blower wheel to motor shaft.
B. Check for bad fan bearings.
5. Problem:
Distribution blower continues to run or will not run
Solution:
A. Check fan limit or heat sensor and cable.
B. Check to see that blower is properly wired.
(See Wiring and Assembly Instructions).
C. Check fuse box or power source.
D. Check power supply.
6. Problem:
Odor from rst re
Solution:
A. The odor from new steel should disappear in a few
hours.
B. If the odor remains, call you dealer immediately. A
bad weld can cause a fume leak.
7. Problem:
Excessive Creosote
Solution:
A. Check the grade of wood you are burning.
B. Make sure your unit is serviced by its own proper
chimney.
C. Check length of ue pipe and its connections.
D. Make sure you are burning the smallest, hottest re
to adequately heat your home.
E. Also see Solutions to Problem one.
8. Problem:
If the re goes out or does not hold over night
Solution:
A. Poor Draft.
B. Incorrect damper settings.
C. Improper ring methods if burning coal.
D. More combustion air needed.
E. Coal not sized to the furnace. We recommend 1”
to 3” diameter pieces of coal.
F. Ashes, if allowed to accumulate in the ash pit, will
not allow passage of the required air for combus-
tion. Keep ash pit clean.
G. This furnace is not to be used with an automatic
stoker unless so certied.
