DISCLAIMER NOTICE
The BTU ranges and heating capacity specications are provided as a guide and in no way guarantee the
output or capacity of this unit. The actual BTU output depends on the type of fuel being burned and its conditions,
the thermostat setting, the draft adjustment and the chimney to which the unit is attached. The actual area
that this unit will heat depends on factors such as the conditions of the building, heat loss, type of construction,
amount of insulation, type of air movement, the location of the unit and more importantly the duct work and
return air facility.
Warning:
Do not alter this appliance in any way other than specied in these instructions. Doing so may void your warranty.
GENERAL INFORMATION
Your 1600EF furnace comes ready for installation. No assembly required. Unpack your furnace and insure that
there is no shipping damage. If damage exist, please contact your dealer immediately. Review the items included
with your furnace located inside the rebox.
1 - 10” Starter Collar
1 - 12” Starter Collar for Cold Air Return
8 - #10 x 3/4 Screws w/ Sealing Washer
1 - Literature Package
This furnace may be installed as a Stand-Alone Central Furnace or as a Supplementary Furnace in the US only.
For Canadian installations, it may be installed as a Stand-Alone Central Furnace Only.
If installed as a Central Furnace, this unit will have it’s own central ducting system and will essentially be your
primary heat source. If installed as a Supplementary Furnace, the 1600EF will assist an Electric, Gas or Oil Fired
Furnace in heating your home by utilizing the existing furnace’s duct work system. The 1600EF must not be wired
in conjunction with the existing furnace. The outdoor furnace may be operated with the supplied wall thermostat
or a 24 volt thermostat that you supply yourself.
The furnace should be placed outdoors on a level noncombustible base, preferably a 4’ x 8’ concrete pad, as
close to the home as clearances to combustibles will allow. If locating the furnace more than 10 feet away from
the home, a minimum of 6 feet of Class “A” HT 2100 All Fuel 6 inch chimney pipe is required - Do not place the
furnace more than 40 feet away from the home. Maintain all clearances stated in this manual.
Class “A” HT 2100 All Fuel 6” Chimney Pipe is recommended for optimum performance and can be purchased
from your local dealer. A Chimney Base Plate should be installed over the ue outlet and sealed to maintain
weather resistance. A 2” clearance to combustibles must be maintained from the pipe. We suggest using either
Simpson Dura-Vent or Metal Fab chimney products for your installation.
If you choose to use single wall stainless, the ue temperatures will be reduced which promotes the formation
of creosote, possibly creating a re hazard. If you use single wall stainless pipe, the minimum clearance to
combustibles is 20”.

Attach the appropriate chimney pipe lengths to the chosen chimney base plate and nish with a rain cap.
Secure the chimney with guy wires to each of the four anchors point on the furnace. Your furnace requires it’s
own chimney system and can not share a ue with another appliance.
Once you have selected a location for the furnace and connected your furnace to a chimney and a 110 volt
GFCI outlet, you will need to commence an initial ring. DO NOT connect the furnace to your duct work at this
time. Your new furnace has a protective coating of oil and paint on the surface which could produce smoke or
odors during the initial ring and will burn off. Build a small re - DO NOT ll the rebox to it’s full capacity for the
initial burn. This initial ring allows the metals and castings to cure.
After completing the ring and allowing it to cool, you are ready to nish the installation. Refer to the remainder
of this manual for detailed instructions.

CHIMNEY REQUIREMENTS
A Class “A” HT 2100 All Fuel 6” Chimney Pipe and Base Plate should be used for the installation. See Illustration.
Place the Base Plate over the ue outlet of the furnace and drill eight(8) pilot holes into the Cabinet Top. Apply
a generous amount of high temperature sealant to the
bottom of the base plate, and around the ue outlet.
Position the base plate over the ue and secure with
the eight(8) screws provided. Then attach the ue pipe
sections.
A minimum chimney height of 6 feet is required not
including the rain cap. In order to determine proper
chimney height above the roof, measure from the side of
the chimney horizontally. As you move up the chimney,
the length increases. Once this measurement reaches 10
feet, this is the base height of the chimney. The chimney
must be 2 feet taller than the base height. If the chimney is
closer than 10 feet from the peak of the roof, the chimney
must be 2 feet taller than the peak of the roof. The 2 feet
measurement does not include the rain cap.
Once correct chimney height is achieved, check the
chimney draft. It should not exceed 0.06 inches of water
column. Then secure with three screws at each joint and
attach guy wires down to the rings located around the
top of the furnace cabinet.
See illustration.

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. Inadequate draft may cause backpufng 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.
CONNECTING HOT AIR DUCT TO FURNACE
We strongly recommend that the hot air duct work be installed by a home heating specialist. If doing the
installation yourself, before you decide which installation will best suit your needs, consult a qualied heating
technician and follow his recommendations as to the safest and most efcient method of installation.
The warm-air supply-duct system shall be constructed of metal in accordance with NFPA 90B, 2-1.1. The plenums
installed to the furnace be constructed of metal in accordance with NFPA 90B, 2-1.3.
Outside the house you must use 10 inch galvanized pipe, wrapped with weather proof, UV resistant insulation.
The 12 inch return may be galvanized pipe and attached to the home so as to not pressurize the home.
NEVER reduce the 10” hot air or the 12” return air as this will result in restricted air ow and cause the furnace to
not operate properly.
NEVER draw cold outside air into the blower housing. By doing so, the furnace’s heat chamber will not reach the
necessary temperature to heat the home.
The duct work should be designed so the external static pressure does not exceed 0.2 inches water column while
developing air velocities of 600 to 1,000 feet per minute in the main trunk duct and 400 to 600 feet per minute at
the registers. The heat outlet should never be less than ten inches (10”) round or 79 square inches.
This furnace must be installed with a cold air return system. The system must be a minimum of twelve inches
(12”) to readily transfer the cold air from the home back to the furnace. If desired, a cold air lter box may be
constructed with a minimum opening of 225 square inches.
The warm-air supply outlet of the outdoor furnace must not be connected to the cold-air-return inlet of an
existing central furnace because the possibility exist of components of the existing furnace overheating and may
cause the central furnace to operate other than intended.
ATTENTION:
This heater needs periodic inspection and repair for proper operation. It is against federal regulations to
operate this heater in a manner inconsistent with operating instructions in this manual.

Types Of Installation
NO DUCT WORK INSTALLATION
Cold air return must be installed in all installations, even those without an air duct system. If you do not, the
furnace will not be able to heat the home. A lter should be installed in the cold air return. Furnace lters should
be checked and cleaned/replaced regularly.
When there is no duct system to connect the furnace to, keep the following in mind:
1. You must separate the hot air duct from the cold air return. Ideally, locate each at opposite ends of the
home. This method will work well in homes that are built on concrete slabs and should create a good air ow.
If you do not, air will not ow evenly through the home.
2. In homes with a basement, you may run the hot air duct to the basement and pull the cold air return from
the main oor. This will create the perfect air ow since hot air rises.
CENTRAL DUCT CONNECTION
When connecting to a central duct system, avoid 90 degree elbows as this will reduce air ow delivery. A duct
run in excess of 40 feet is NOT RECOMMENDED. The air ow and heat output will be greatly decreased.
Run 10” insulated hot air duct from the outdoor furnace through a wall or window of the structure. Then attach
a exible hot air duct to the existing duct work. Connect the duct with a 45 degree elbow or at an angle so the
hot air from the outdoor furnace is delivered downstream. This will insure proper air ow into the system.
Avoid delivering hot air through an air conditioning coil as this will cause an obstruction reducing heat output.
The following illustrations may be used as examples for your installation.

Installation Examples
Installation #1
With this installation, a back draft damper (optional)
is inserted into the heat run before the plenum of
the existing furnace to prevent air from the existing
furnace to blow back into the furnace when it is not
in use. When a back damper is employed, it should
be located as close to the existing furnace plenum as
practical.
INSTALLATION #2
The bafe on this system should be made the full width
of the furnace plenum in order to properly direct the air
into the distribution ducts.
INSTALLATION #3
Extending the hot air duct from the furnace into the
existing plenum will help direct the ow of air from the
furnace as well as the ow in the existing furnace. Ducting
entering the existing plenum at an angle (approximately
45 degrees) will facilitate air ow from the furnace while
diverting air from the existing furnace.

electrician.
1. To replace the Honeywell Limit Control (A): Unplug from
power supply
The control may be removable thru the access panel on
item “B”. However it may be easier to remove item “B”
entirely for better access. Remove item “B” by means of
the eight(8) screws. If siliconed, use a utility knife to score
the silicone along the edges of the part. Take off the cover
of the control (A), remove the three wires, and continue to
remove the control by means of the two screws retaining
it. Use the wiring diagram in the rear of this manual to reconnect the new control. Reattach item “B” and re-silicone
all the seams with weather resistant silicone.
2. To remove the return air box (D): Unplug from power
supply.
If siliconed, use a utility knife to score the silicone along the
edges of the part. Remove item “B” as described above.
Then remove the four(4) screws down each side and the
four(4) across the top of the return air box. Pull the box
back away from the unit enough that you can reach in to
remove the snap-in plug (C) from the top of the box. The
power supply cord will need to be feed back thru the plug
in the bottom of the air box for complete removal. When reattaching, make sure that the three plugs in the top of the
Fan Center (G) are properly plugged in. Do not forget to put
the snap-in plug (C) back in place. Re-silicone all the seams
with weather resistant silicone.
3. To remove the Distribution Blower (E): Unplug from
power supply.
Remove items”B” and “D” as described above. Unplug
the blower from the top of the Fan Center (G). Remove the

4. To remove the Blower Motor: Unplug from power supply.
Perform number 3 above. Before removing the motor from
the housing, measure two things:
1. The distance from the edge of the motor to the edge
of the motor bracket. Record (d1) _________________
2. The distance of the shaft remaining outside the coupling
on the blower wheel. Record (d2) __________________
These two measurements dictate the position of the blower
inside the housing and is critical in determining motor
longevity. Repositioning of the blower motor, bracket, and
wheel in respect to one another should keep as close to the
factory position as possible.
Remove the three(3) screws (I) from the blower housing.
Then loosen the bolt (J) on the motor shaft. Next, loosen or

Firebrick And Bafe Replacement
FIREBOX BRICK REPLACEMENT
This furnace comes from the factory with the rebrick
installed. However, if brick replacement is necessary,
follow these instructions. Before furnace operation,
remove the brick retaining strip. This piece is used
during shipping to reduce brick damage.
There are 6 full brick and 1 half brick per side. Install
the half brick rst by putting the bottom of the brick
in rst and let it rest against the rebox side and re
grates. Then slide it to the rear. After that, install the #2,
#3, #4, #5 & #6 brick, sliding the 6th brick forward to
allow for the 7th brick. Repeat for opposite side.
NOTE: Prior to operation, be sure to remove the
brick retaining strips.
BAFFLE/BRICK REPLACEMENT
If bafe replacement is necessary, slide the bafe
out until you can access the nuts thru the ue outlet.
Once the nuts have been removed, slide the bafe off
the rod and thru the opening in the rebrick. You may
have to remove one of the rebrick to make bafe
removal easier.
There are 4 full brick and 1 half brick in the top of the
furnace. Install the brick by inserting one end of the
brick angled upward and then allowing the opposite
end to rest on the rebox lip. Lay the brick between
the spacer and rebox back. Slide the bafe to the
rear and let it rest on that half brick. After installing
brick #2 in the front, install #3 and slide it under the
bafe. Finally install bricks #4 and #5.

Testing And Operating Procedures
GENERAL FURNACE OPERATION
After installation of the furnace is complete, it is ready for operation. The Honeywell Limit Control, in conjunction
with a wall thermostat, operates the distribution blowers and the motorized draft on the front of the furnace. The
limit control is located on the rear of the furnace in the upper left corner and is accessible by removing the two
screws in the cover plate. DO NOT operate your furnace with this plate removed! The control can be adjusted
to your desired blower On/Off times. The factory settings are 100/150/200. The wall thermostat setting operates
the ON time of the motorized draft. If the temperature is below the setting on the wall thermostat, the motorized
draft will come open. (Recommended setting at 5 to 10 degrees higher than other heating thermostats.) The rst
two set points on the limit control operates the distribution blower. When the furnace plenum reaches the second
set point on the limit control, the distribution blower will come on. If the temperature falls to the rst set point, the
distribution blower will shut-off. The distribution blower is a three speed blower and can be manually adjusted by
means of the three position switch located behind the sliding access panel on the cold air return box. When the
furnace reaches the third set point on the limit control, the draft blower will shut-off. The draft blower will come
back on if the temperature falls below the setting on the wall thermostat.
TESTING
1. Check the motorized draft by turning the room thermostat up high enough so that the motorized draft
opens. Then lower the thermostat setting to ensure it closes off.
2. Use a sheet of newspaper to test your draft by placing it inside the furnace and lighting it.
STARTING A COAL FIRE
• Shut off FAD when fuel door is open
• Open all draft controls on your furnace. Pull the slide bafe forward.
• Place about 10-15 lb. of coal in on the shaker grates. It should come up to about half of the rst rebrick
level.
• Place crumpled paper over the coal and crisscross a couple handfuls of dry kindling wood 3/4” in thickness
on top of paper.
• Ignite the paper and close loading door. Wait about 30 minutes until coal re is established before adding
more coal. NOTE: NEVER load coal over the level of rebrick.
• Close by-pass damper and set all draft controls to your own needs. It may take 3 to 4 coal res to determine
how your local coal and the Clayton Furnace reacts together. Adjusts drafts accordingly.
• When loading with a good bed of coals in the morning - Open by-pass damper.
1. In normal shaking, only rock the grates a small amount to sift ash through. Do not agitate the re bed too
often. This practice will waste coal. If glowing coal is visible in the ash pan, you have shaken to much.
2. Remove all ashes every day from ash pit.
CAUTION: Ashes should be placed in a metal container with a tight tting lid. The closed container of ashes
should be placed on a non-combustible oor or on the ground well away from all 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 coals have thoroughly cooled.
3. With your poker, push hot burning embers to the rear of the unit and add green coal in front. NEVER load
over height of rebrick. This can result in damage to your furnace and home.
4. Close by-pass damper.
• Too much draft air will cause clinkering of coal and will waste heat up the chimney. Shut draft down to as
low a point as you can and still heat your home.
1. NOTE: Never stand in front of loading door when opening it. Stand to the side.
2. NEVER completely cover the live re with fresh coal. Always leave a generous area of glowing coal at the
top of the re and at the rear.
3. Always keep the ash pit clean.
• If the re goes out or does not hold overnight, look for:
1. Poor draft.
2. Incorrect damper settings.
3. Improper ring methods for coal being used.
4. More combustion air needed.
5. Coal not sized to the furnace. We recommend 1” to 3” diameter pieces of coal.
6. Ashes, if allowed to accumulate in the ash pit, will not allow the passage of required air for combustion. Keep
ash pit clean.
7. This furnace is not to be used with an automatic stoker unless so certied.
-11-
Page 12
• There are ONLY two types of coal allowed for use in this furnace: Bituminous Coal (soft coal) and Anthracite
Coal (hard coal). NEVER USE Cannel (or Channel) coal or Brown (Lignite) Coal.
• See our Bulletin RC454 at the rear of this manual for the best information available on burning coal.
• DANGER: Risk of Fire or Explosion - Do not burn garbage, plastics, gasoline, drain oil or other ammable
liquids. Plastics, when burned, form hydrouoric and hydrochloric acids which will damage and destroy your
furnace pipe and chimney. The burning of trash or oil can result in an extremely hot re and is sometimes a
cause of chimney res. NEVER BURN GREEN WOOD OR TIRES.
• WARNING: Risk of Fire - Do not operate with ue draft exceeding .06 inches of water column and must be set
with a draft gauge to maintain a steady draft. (Barometric Damper recommended.)
OPERATING NOTES
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;
Burning these materials may result in release of toxic fumes or render the heater ineffective and cause smoke.
CAUTION: Never use gasoline, gasoline-type lantern fuel, kerosene, charcoal lighter uid, or similar liquids to start
or “freshen up” a re in the furnace. Keep all such liquids well away from the furnace while it is in use. This 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 heater in a manner inconsistent with operating instructions in this manual.
8. Manure or animal remains;
9. Salt water saturated materials;
10. Paper products, cardboard, plywood, or
particleboard. The prohibition against burning
these materials does not prohibit the use of re
starters made from paper, cardboard, saw dust,
wax and similar substances for the purpose of
starting a re in an affected heater.
VISIBLE SMOKE
The amount of visible smoke being produced can be an effective method of determining how efciently 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 specic unit to produce the smallest amount of visible
smoke.
EFFICIENCY
Efciencies 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. The higher heating value is
when water leaves the combustion process completely condensed. Higher burn rates are not always the best
heating burn rates; after a good re is established a lower burn rate may be a better option for efcient heating.
A lower burn rate slows the ow of usable heat out of the home through the chimney, and it also consumes less
coal.
• Do not operate with the fuel loading or ash removal doors open.
• Do not store fuel or other combustible material within marked installation clearances.
• Inspect and clean your ues and chimney regularly.
• CAUTION: Hot Surfaces - Keep children away. Do not touch during operation. Maximum draft marked on
nameplate.
• Equip your home with re extinguishers and smoke detectors appropriately located.
• Coal should be placed directly onto the cast iron shaker grate of the Clayton furnace. Do not use additional
grates and/or irons.
• Do not allow ashes to build up higher than 2” above grates.
• Never allow the ashes in the ash pan to touch the grate section. REMOVE ASHES FREQUENTLY!
• Be extremely careful when removing furnace ash pan; it can get very hot.
• With new steel, there is a small amount of oil or dirt on the metal. You may smell an odor. This is normal during
the rst operation. You may want to build a small re in the furnace to “burn off” this dirt and oil before
installing the duct work.
• The furnace is designed to burn air dried coal at a predetermined ring rate. Over ring could result in
damage to the heat exchanger and cause dangerous operation. Over ring occurs when the ash door is
left open during operation or a highly volatile fuel, i.e. large amounts of small kindling, is used. If any portion
of the connector pipe glows orange or red, you are in an over-ring situation. Close all dampers.
• When tending the rebox always pull the bafe slide rod out prior to opening load door. Open load door
slowly to avoid a “ash back”. After closing load door, push the bafe slide rod to the rear.

• In event of chimney re, shut all draft controls and call your re department immediately. Alert everyone in
the house. If the re is still burning vigorously, throw baking soda into rebox or discharge a re extinguisher
into the rebox. After chimney re is over, completely inspect system for damage before further use.
• NEVER throw water on the re or at the furnace, as rapidly expanding steam could result in a severe
scalding.
• Slow res: It is not recommended burning the Clayton furnace any more than necessary early in the fall and
late spring, as you cannot keep the rebox hot enough (without overheating your home) to burn gases. Slow
res can cause excessive creosote build-up in smoke pipe, chimney and rebox.
• Inspect air lters regularly. The air lter should be changed at least every 30 days.
• Oil motors every 90 days with a few drops of 30 wt. oil.
• Check the t on the load door. It must t tightly. If it does not, check for deterioration or wear of the ceramic
rope seal. Replace defective seals.
• In the event of a power failure, the furnace will not distribute heat to the home. We recommend the use of a
back-up generator, 2,000 watts minimum, for continued use until regular power is restored
• Inspect ue pipes, ue pipe joints and ue pipe seals regularly to ensure that smoke and ue gases are not
drawn into, and circulated by, the air-circulation system.
• CAUTION: clean out of the heat exchanger, ue pipe, chimney, and draft inducer if used, is especially
important at the end of the heating season to minimize corrosion during the summer months, caused by
accumulated ash.
NOTE: For further information on using your furnace safely, obtain a copy of the National Fire Protection
Association publication “Using Coal and Wood Stoves Safely.” NFPA NO. NW-8-1974. The address of the NFPA is
470 Atlantic Ave., Boston, Massachusetts 02210.
THIS IS A COAL only FURNACE AND SHOULD NOT BE ALTERED IN ANY WAY! DOING SO WILL VOID YOUR
WARRANTY!
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. The chimney should be
inspected at least twice monthly during the heating season to determine if a creosote build-up has occurred. If
creosote has accumulated, it should be removed to reduce the risk of a chimney re.
OVER FIRING
Attempts to achieve heat output rates that exceed heater design specications can result in permanent
damage to the heater. Whenever ashes get 3 to 4 inches deep in your rebox or ash pan, and when the re has
burned down and cooled, remove excess ashes. Leave an ash bed approximately 1 inch deep on the rebox
bottom to help maintain a hot charcoal bed.
ASH REMOVAL AND DISPOSAL
Ashes should be placed in a metal container with a tight-tting lid. The closed container of ashes should be
placed on a noncombustible oor or on the ground, away from all combustible materials, pending nal disposal.
The ashes should be retained in the closed container until all cinders have thoroughly cooled.
SMOKE AND CO MONITORS
Burning coal 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 conned
areas can be dangerous. Make sure your 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 insure good control over the combustion, maximum efciency 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 operation. This unit’s doors use a 3/8” diameter rope gasket.
OPERATIONAL TIPS
• Get the appliance hot and establish a good coal bed before adjusting to a low burn rate (this may take 30
minutes or more)
• Use smaller pieces of wood during start-up and a high burn rate to increase the stove temperature
• Burn small, intense res instead of large, slow burning res when possible
• Learn your appliance’s operating characteristics to obtain optimum performance.

Trouble Shooting And Problem Solving
Problem Solution
• Check chimney draft. Check for blocked chimney or ue pipe. Use mirror to
check chimney clearance.
• Check ash pit — if it is too full, empty.
• Make sure all of chimney mortar connections are airtight.
• Check ash drawer. Make sure it’s airtight.
• Check chimney for possible down-draft caused by taller surrounding trees or
objects. Correct with proper chimney vent cap.
1. Smoke puffs from furnace
2. Inadequate heat being
delivered to your home
3. Excess smoke or ames coming
out door when refueling
4. Distribution blower vibrating
5. Distribution blower continues to
run or will not run
6. Motorized draft stays open or
will not close
7. Odor from rst re
8. Excessive Creosote
9. If the re goes out or does not
hold over night
• Check the possibility of a cold chimney forcing cool gases backward.
Remedied by properly insulating chimney with non-combustible liner — noncombustible insulation.
• Fuel may be too green.
• Make sure no other fuel burning devices are connected to the chimney
impairing the draft.
• Check chimney draft, it should be .06 inches of water column. This service is
provided by a certied chimney sweep.
• Check home insulation — is it adequate?
• Check hook-up to furnace — is it installed correctly?
• Cool air inlet may be inadequate.
• Make sure your hot air duct (and other duct work) is airtight.
• Is air to the blower available?
• Wait 15 seconds and open door SLOWLY — then refuel.
• Check length of ue pipe to chimney.
• Make sure chimney cap is not too close to the top of the chimney.
• Check chimney draft — make sure chimney ue pipe is clean and chimney is of
adequate height.
• Make sure you’re not suffocating the re with excessive amounts of unburned
coal.
• Slide bafe should be pulled out prior to load door opening.
• Tighten blower wheel to motor shaft.
• Check for bad fan bearings.
• Check fan limit or heat sensor and cable.
• Check to see that blower is properly wired. (See Wiring and Assembly
Instructions).
• Check fuse box or power source.
• Check power supply.
• Check wiring.
• Check thermostat or thermostat wire for short.
• Make sure temperature is calling for heat.
• The odor from new steel should disappear in a few hours.
• If the odor remains, call you dealer immediately. A bad weld can cause a fume
leak.
• Make sure your unit is serviced by its own proper chimney.
• Check length of ue pipe and its connections.
• Make sure you are burning the smallest, hottest re to adequately heat your
home.
• Also see Solutions to Problem number 1.
• Poor Draft.
• Incorrect damper settings.
• Improper ring methods if burning coal.
• More combustion air needed.
• Coal not sized to the furnace. We recommend 1” to 3” diameter pieces of coal.
• Ashes, if allowed to accumulate in the ash pit, will not allow passage of the
required air for combustion. Keep ash pit clean.
• This furnace is not to be used with an automatic stoker unless so certied.

A guide to Burning coal in your furnace
Furnaces that are capable of burning coal usually will burn both Bituminous and Anthracite coal. Anthracite is
perhaps the best coal fuel because of its long even burn time, high heat output, and cleanliness which make it a
good choice for the home. However, keep in mind it is a much more difcult fuel to use, requires more care and
patience, is not so widely available, and is usually much more expensive than Bituminous.
SIZE OF COAL
Most sizes of Bituminous Coal will work in a coal furnace; for best results we recommend large “nut” coal to small
“egg” coal (1-3/4” diameter to 4” diameter). When burning Anthracite, use “egg” or “broken” with sizes between
2-5/16” thru 4-3/8”. Note that it is important to the long life of your stove to buy coal which has been sized and
cleaned. Cleaning insures removal of rocks and other minerals. Never use coal smaller than 1” or larger than 5”
in diameter. Small sized coal will smother the re. Too large a size of coal will not burn well.
STOVE OPERATION
All coal res should be started with wood which will allow the re to get hot enough to ignite the coal. The best
ignition res utilize dry pine or other resinous soft woods as kindling, with hard wood (oak, hickory, ash) added to
increase the heat prior to addition of the coal.
Before starting the re, open the stove pipe damper (if equipped), turn the thermostat to high, open the ash
pit door and feed door, place newspaper and nely split kindling on the grate, light the paper, add larger hard
wood after the kindling is burning brightly. Caution: Never use gasoline, lantern fuel, kerosene, charcoal lighter
uid, or other ammable liquids to start or freshen up a re in any heater. Place the larger pieces of wood on the
re so that they are slightly separated and form a level for the addition of coal. It will take 10 to 20 minutes before
this wood is thoroughly ignited. Adding coal too soon will cut the air supply and smother the re.
BURNING BITUMINOUS
Once your kindling and wood re has produced a bed of well established coals, start adding coal in layers
allowing each to ignite before adding more. Bituminous has a high volatile content and, as a result, should be
red with the “conical method” - with the highest portion of your re bed in the center of the rebox. The rst
ames will be long and generally orange or yellow and produce quite a bit of smoke. As the gases burn off the
ames become shorter, change color and produce less smoke.
Once the re is WELL ESTABLISHED add coal to the center of the rebox forming the cone. Burning in this fashion
allows heat to drive off the volatile gases, and turbulence created increases the burn efciency. There will have
to be some experimenting with the individual setup as no two chimney’s or installations are going to be the same.
Just remember to allow enough air to enter the rebox and keep the stove pipe damper open so that volatiles
are properly burned. Before refueling, take the time to break up the cone a little with a poker, especially if it has
caked over or formed a crust. But, be careful not to mix the coal as this increases the chances of forming clinkers.
When shaking the grate(s) be gentle. Just a few short movements - a couple of “cranks” - is better than a lot of
agitation. The objective is to remove a small amount of the ashes without disturbing the re. Stop when you see
a glow in the ashes or the rst red coals fall into the ash pan. Excessive shaking wastes fuel and can expose the
grate(s) to very high temperatures which can cause warpage or burnout.
For overnight operation (long duration burn time) shake the re and add coal, retaining the center cone. Once
the volatiles are burned off, close the feed door and adjust the stove pipe damper, if equipped. Then adjust the
thermostat to the desired heat level.
More MAINTENANCE will be needed with bituminous coal than with anthracite coal as more soot will collect on
heating surfaces and in pipes, requiring more frequent cleaning.
ANTHRACITE
Add a thin layer of coal (preferably smaller chunks) to the wood re, being careful not to disturb it too much or
cut off the draft. Then, add a second heavier layer after the coal is ignited and burning well. If necessary, add a
third layer to bring the coal up to the top of the front liner (not above!). Be sure to close the ash door.
Before adding further fuel, be sure to leave a red spot of glowing coals in the center of the rebox to insure that
the re has not been smothered and to help ignite the gases given off by the new charge. A deep charge will
give a more even heat and a longer re, but it may take one to two hours before the whole bed is fully ignited.
-21-
Page 22
Bulletin RC454
When the re is well established and the room is becoming warm, partially close the dampers. Some experimenting
will have to take place with each particular setting of all dampers and controls as the chimney provides the
draft necessary to not only exhaust the smoke, but to pull combustion air into the heater as well - and no two
chimney’s perform the same. Under ideal draft conditions, one should be able to turn the secondary air supply
below the feed door (some models) to a near closed position - but leave the ash pit damper at least partially
open to prevent the re from going out. Adjust the stove pipe damper to reduce the draft on the re. With
anthracite there will be short blue ames above the coal, except when the re is started or a new charge is
added. If, however, there is no ame then the re needs more air from the bottom (unless it is near the end of its
burn cycle and needs to be recharged).
Only when the coal is burned down to half its original depth it is time to add fresh coal. When doing so, open the
stove pipe damper and turn the thermostat damper to high, which will allow the re to burn off any accumulated
gases. Open the feed door, and with a small rake, hoe, or hooked poker pull the glowing coals to the front of
the rebox. Try not to disturb the re too much. Next, add a fresh charge to the back being careful not to seal off
the top. Close the feed door, but leave the spin damper (or thermostat) open for a few minutes until the volatile
gases have burned off. It is not necessary to shake down the ashes each time you refuel the furnace. Experience
will be your best teacher.
BANKING THE FIRE
For extended operation, such as overnight, the re will need to be banked. To do so heap coal up along the
sides and back of the rebox so that the re gradually burns it over a longer period of time. The intensity of the
re will also be reduced without letting it go out. Follow the same procedure as for refueling. If possible, avoid
shaking, as a heavier layer of ash will help reduce the intensity of the re during this time. After loading, let the re
establish itself for about 30 minutes. Then close your damper and automatic control to the point where the house
does not become too cold. It is important that you begin banking early enough before retiring or leaving that
you can make necessary adjustments after the re is well established.
To revive a coal re that is almost out, (1) open the ash door and stove pipe damper and close the spin damper
under the door to get a good draft through the grate. (2) place a thin layer of dry coal over the entire top of
the re. DO NOT POKE OR SHAKE THE FIRE AT THIS TIME! (3) after the fresh coal has become well ignited shake the
grate (just a little), refuel.
DO NOT burn coke, charcoal, high volatile bituminous coal, sub bituminous, lignite or cannel coal (sometimes
called channel coal or candle coal).
NEVER burn wax or chemically impregnated sawdust logs - their intended use is for replaces only.
NEVER ll the stove or furnace above the rebrick or cast iron liner.
