General Information
The Fire Chief Furnace has been engineered to accommodate the heating requirements of the average sized home, even during winter’s
coldest months. It is constructed with high grade, heavy gauge steel and is continuously welded to assure the highest structural strength.
In addition, the rebox is lined with rebrick to ensure many years of energy efcient service. The cast iron door is custom tted to
provide an airtight seal, greatly extending the burn time and ensuring maximum efciency in fuel consumption. The heavy-gauge cast
iron grate, designed for maximum heat transfer, allows for convenient ash removal and reduced maintenance.
Your Fire Chief Furnace is designed to be either a supplemental or central heating source for your home. This wood and coal burning
furnace may be installed in parallel with a properly operating electric, gas or oil-red central furnace, listed or certied in accordance
with a nationally recognized safety standard, and within clearances specied on the nameplate. When in a parallel installation the static
pressure of the central furnace plenum may not exceed 0.15 water column inches and the maximum setting on central furnace limit
switch is 182°F. With the Fire Chief Furnace in an “Interconnection Arrangement” your furnace should be upstream of the central furnace.
The Fire Chief Furnace warm air supply should never be connected to return air for the central furnace. A qualied installer should
perform the installation.
IMPORTANT: FOR TECHNICAL SUPPORT OR CUSTOMER SERVICE
ISSUES, DO NOT RETURN TO THE DEALER (THE DEALER DOES NOT HAVE
REPLACEMENT PARTS), CALL 1-800-875-4788.
Forced Hot Air Circulation:
The plenum size of your Fire Chief Furnace must not be reduced to less than 12 inches in diameter or 113 square inches, and must
provide a minimum of 18 inches between the top of your Fire Chief Furnace and the main trunk connection. The plenum attached to the
furnace must be constructed of metal. The warm air supply duct system should be constructed of materials with a minimum temperature
rating of 250° Fahrenheit.
Clearances:
Unit must be placed on a non-combustible oor. This oor must extend at least 16 inches in front, 8 inches on either side of fuel loading
door and ash removal drawer, underneath the chimney connector and must extend 2 inches on either side of the chimney connector. The
furnace must maintain the following clearances to combustibles:
• Heat plenum = 2 inches
• Chimney connector = 18 inches
• Front = 48 inches
• Rear = 31 inches
• Sides = 12 inches
• Main furnace = 12 inches
These are minimum clearances and should be strictly followed. In the case of a power outage, a dangerous level of heat accumulation
may develop. Do not store fuel or other combustible materials within the above clearances.
Location and Installation
NOTE: Before beginning installation, consult proper local authorities regarding local codes governing all such applications and
installations.
DO NOT CONNECT THIS UNIT TO A CHIMNEY FLUE SERVING ANOTHER APPLIANCE. Your furnace must be placed on a non-
combustible oor. Position the furnace as close to the chimney as possible. Air for combustion must be provided into the room where the
furnace is located. Allow air free access to the furnace for combustion and ventilation.

Chimney Types and Recommendations
See Diagram on page 8.
Safety requirements demand that your Fire Chief Furnace be connected to “Class A” HT2100 All Fuel, or stainless-lined masonry
chimney ONLY.
By denition, “Class A” refers to either a lined masonry chimney or all fuel factory-built chimney. Although experts have expressed
differing opinions as to which system is the best, it is a matter of what you nd most suitable. Regardless of your choice of chimney
type, for model FC300F, a minimum 6-inch diameter chimney is needed. In order to create the most effective draft, the chimney size
should not exceed 12 inches, with a maximum .08 water column inches of draft. The ue draft can be measured with the use of a draft
gage or manometer. If there is more than .08 water column inches of draft, it can be adjusted with the installation of a ue damper.
The stovepipe required to connect the furnace to the chimney should be a minimum of 24 gauge black or stainless steel. NEVER USE
GALVANIZED PIPE. Horizontal run should not exceed 5 feet and should have a minimum rise of 2 inches per foot. No installation
should have more than 2 elbows, a 45° elbow is recommended over a 90° elbow.
As a safety precaution, all pipe selections should be fastened together with a minimum of 3 sheet metal screws. For your convenience,
the crimped male ends of the pipe should point toward the furnace to form drip-free connections, thereby reducing the possibility of
creosote leakage from the joints. Installing a heat reclaimer in the pipe is not recommended because it reduces the stack temperature
thus causing creosote formation. Installing a manually operated cast iron damper in the stovepipe between the furnace and the
chimney pipe is recommended. The addition of a damper will greatly assist in regulating the re and achieving optimum results. Always
install a tee with clean-out cap to the chimney outlet on the back of the furnace. This allows for easier cleaning of the chimney system.
Never use a 90° elbow off the back of the furnace.
When using a masonry chimney, you must line the chimney with a stainless steel liner. The stainless steel liner will keep the chimney
temperature hotter for better draw and signicantly reduce the creosote formation in the chimney. If using this method, a 6-inch
stainless liner should be used for model FC300F.
WARNING- RISK OF FIRE:
• Do not operate with ue draft exceeding .08 water column inches (19.9 Pa).
• Do not operate with fuel loading door or ash removal drawer open.
• Do not store fuel or other combustible materials within marked installation clearances.
• Inspect and clean ues and chimney regularly.
DANGER: Risk of Fire and Explosion. Do not burn garbage, gasoline, naphtha, engine oil, or other ammable liquids/inappropriate
materials.
WARNING:
• NEVER use galvanized pipe in your chimney connection, it produces poisonous gases when subjected to extreme
temperatures.
• USE only lined masonry or manufactured Class “A” HT2100 All Fuel Chimney for your furnace.
• INSPECT chimney system periodically for structural integrity.
• CLEAN the chimney system regularly to prevent creosote accumulation.
• DO NOT CONNECT THIS UNIT TO A CHIMNEY FLUE SERVING ANOTHER APPLIANCE.

The termination cap
should be designed to
inhibit down-drafting
without restricting the
exhaust discharge.
For the best draw
the chimney
termination
should be at least
2 feet above the
highest portion
of the roof that
is within a 10
foot radius of the
chimney.
USE LISTED UL 103 TYPE
HT 2100 CHIMNEY ONLY.
When using a brick chimney, you must line the entire
chimney with stainless steel liner. The liner must be the
correct size for the furnace. (FC300F: 6 inch liner)
The diameter of the chimney stack should be consistent
throughout length of the chimney
The chimney size should be at least as large as the
exhaust stack on the furnace, but not more than twice
its size.
The chimney stack should have
a built in airtight clean out.
WARNING: Do not operate with
clean out uncapped.

9
Duct Runs
Ductwork should be designed so the external static pressure does not exceed .02 water column inches while developing air velocities of
450 - 600 feet per minute at the registers. The heat outlet area should never be less than 12 inches round or 113 square inches. The
furnace can be installed with a cold air return system, or the return air can be drawn from the basement. If the return air is drawn from
the basement, you will have to install 3 “open and close” air register vents in the return air duct connected to your existing furnace; the
air will take the path of least resistance without using ductwork to connect the two together. The return air system should be a minimum
of 10% larger than the heat outlet to readily transfer the cold air back to the furnace. Avoid using 90° elbows in duct runs; 45° elbows
provide better airow and less resistance. CAUTION: The warm air supply outlet of the supplementary furnace should not be connected
to the cold air return inlet of the central furnace, because a possibility exists for components to overheat and cause the central furnace to
operate other than intended.
Canadian Requirements for Supplemental/Add-On Furnaces
• DO NOT USE DUCT ELBOWS HAVING AN INSIDE RADIUS OF LESS THAN 6 inches (150mm) ON OIL,
ELECTRIC, OR GAS FURNACES.

Installation of Optional Equipment
Back Draft Damper:
OPTIONAL ACCESSORY PART #AM-BD8 Back Draft Damper
The Back Draft Damper may be installed in either a vertical or horizontal section of the 8”round hot air duct. It should be positioned as
close to the plenum opening of the FC300F as practical. Press the female end of the damper over the FC300F furnace collar or male end
of the duct pipe. When properly positioned, the arrows on the air ow decal point “away” from the FC300F.
NOTE: The back draft damper may cause the blower to cycle on and off frequently. If this occurs, install a sheet metal screw inside of the
damper to prevent the apper from closing completely. This will allow heat to rise off the furnace.
Manual Back Draft Damper:
OPTIONAL ACCESSORY PART #AM-MD8 Manual Back Draft Damper
The Back Draft Damper may be installed in either a vertical or horizontal section of the 8”round hot air duct. It should be positioned as
close to the plenum opening of the FC300F as practical. Press the female end of the damper over the FC300F furnace collar or male end
of the duct pipe. When properly positioned, the arrows on the air ow decal point “away” from the FC300F.
NOTE: The back draft damper handle closes off the duct, stopping the cool air from your air-conditioner from owing back through the
furnace. Diagrams above show horizontal and vertical installation. OPEN THE DAMPER AT THE BEGINNING OF HEATING SEASON
- IF THE DAMPER IS IN THE “CLOSED” POSITION, IT WILL CAUSE THE BLOWER TO RUN CONTINUOUSLY AND CAUSE THE
FURNACE TO OVERHEAT CAUSING THE BLOWER TO FAIL.
VERTICAL INSTALLATION
NOTE: Position so that air ow will
open damper from bottom.
HORIZONTAL INSTALLATION
NOTE: Position so that air ow will
open damper in the direction of

BURN WOOD AND COAL ONLY!
General Operation
Types of Wood to Use:
We advise using only dry, seasoned hardwoods in your Fire Chief Furnace rather than high resin woods such as pine. Firewood should
be cut at least one full season prior to the time of its intended use, for optimum heat output. Firewood should be stacked to provide a free
ow of air between the logs, thus allowing more rapid seasoning of the wood. If wood is stored outdoors, it should be completely covered
year round to protect it from moisture and exposure to the elements.
FUEL RECOMMENDATIONS:
• FC300F – 22 inch maximum log length
Use extreme caution when opening the door during operation, temperatures can exceed 300°F. Wait at least 10 seconds after releasing
the latch, and then proceed to the fully open position. Opening the door in this manner is designed to eliminate the possibility of gaseous
ignition. Heat resistant gloves are recommended when opening the fuel door, regulating the spin draft, or emptying the ash pan.
CAUTION: HOT SURFACES. KEEP CHILDREN AWAY. DO NOT TOUCH DURING OPERATION.
CAUTION:
• INSPECT FLUE PIPES, JOINTS AND SEALS REGULARLY TO ENSURE THAT SMOKE AND FLUE GASES ARE
NOT DRAWING INTO, AND ARE NOT BEING CIRCULATED BY THE AIR-CIRCULATION SYSTEM.
• CLEANING OF THE HEAT EXCHANGER, FLUE 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 THE ACCUMULATED ASH.
• Never use chemicals or gasoline to start or maintain your re.
• Do not burn oil, garbage, trash, plastic, or any fuel other than wood or coal in your furnace. Doing so will void the
warranty.
WARNING: – RISK OF FIRE
• DO NOT operate with ue draft exceeding .08 water column inches (19.9 Pa).
• DO NOT store fuel or other combustible materials within marked installation clearances.
• Inspect and clean ues and chimney regularly.
• DO NOT operate your furnace with the fuel door or ash drawer open.
WARNING: NEVER fuel your furnace with wet, unseasoned wood or wood that has been exposed to a recent rainfall. Burning wood with
high moisture content will cause a rapid accumulation of hazardous creosote, which has been proven to be the most common cause of
ue res. NEVER burn plastics, any wood product containing glue, or wood treated with chemical preservatives in your furnace. The
combustion of these substances may release harmful, toxic gases.
DANGER: RISK OF FIRE OR EXPLOSION – do not burn garbage, gasoline, naphtha, engine oil, or other ammable liquids/inappropriate
materials.
Supplemental Outside Combustion air may be necessary if:
• The solid-fuel-red appliance does not draw steadily, smells, experiences smoke rollout, burns poorly, or back-drafts
whether or not there is combustion present. Opening a window slightly on a calm day may alleviate these symptoms.
• The house is equipped with a well-sealed vapor barrier and tight tting windows, and/or has any powered devices
which exhaust house air.
• There is excessive condensation on windows in the winter.
• A ventilation system is installed in the house.

BURN WOOD AND COAL ONLY!
First Wood Fire:
Place several crumpled newspapers on the grate with some dry kindling layered on top of the papers, then ignite the newspaper. When
the kindling is burning, add several small pieces of wood, allow wood to fully ignite. After about 20 minutes the re should be established,
allowing you to add more wood – do not overload which would smother the re. Add more wood slowly, so the ames have time to engulf
the fresh wood. Once the re is burning and there is a glowing ember bed, adjust the draft to achieve desired burn pattern. Learning how
to adjust the draft to maintain the desired temperature for your home may take several days. After a short time you will know which settings
and adjustments work best for your home.
Do not over-re the furnace. Over-ring by overloading/over fueling the furnace causes the metal to superheat and expand, then cool
rapidly, which causes cracking, therefore voiding the warranty. Over-ring or abuse can easily be determined upon inspection.
It will take about 40 minutes to establish a bed of hot embers. Once you have achieved the hot ember bed, add larger pieces of rewood.
Within 30 to 40 minutes, adjust the spin draft and the damper to obtain optimum performance.
NOTE: Your new Fire Chief Furnace is capable of producing a very high BTU output. Do not fuel your furnace to capacity upon initial ring.
It’s recommended that you become thoroughly familiar with your Fire Chief Furnace before operating at full capacity. The new steel and
metal components of the furnace have a protective coating or paint on the surface which could produce an odor during the break in period.
Adequate ventilation within the home and furnace room or area is recommended during the initial ring and break in period to accommodate
this possibility. Your new Fire Chief Furnace is classied as having airtight construction. This type of design should enable you to
experience an average burn time between 6 and 8 hours per full load of fuel (dry, seasoned hardwood). However, abnormally cold weather
may reduce the burn time somewhat, but if your burn cycle is signicantly less, for instance, 2 to 4 hours, you are over-ring your furnace.
This type of occurrence is usually symptomatic of heat demands in excess of furnace capacity. Contact an authorized professional to
determine if your Fire Chief Furnace has been improperly sized for your home.
Loading Wood:
When opening the fuel door during operation, wait 10 seconds after releasing the rst latch, then open the door the rest of the way. The
dual latch system has been incorporated as a safety feature, designed to eliminate the possibility of gaseous ignition. Laboratory testing
has determined that when incomplete combustion occurs the partially spent fuel sometimes concentrates large amounts of potentially
hazardous gases within the re chamber. If the door is opened suddenly under these conditions, the oxygen may combine with these
gases and cause ignition referred to as “back ash.” Use EXTREME CAUTION when opening the fuel door.
When reloading the furnace, spread embers evenly over the grate. Place smaller pieces of wood or coal on the hot embers and layer larger
pieces on top of them. Finally, due to the wide variety of temperature ranges during the winter, you may experience periods when it is not
necessary to fully load the re chamber in order to maintain an overnight burn. Your Fire Chief Furnace will operate at the highest efciency
by adding fuel in amounts needed to maintain comfortable temperatures in your home.

13
Starting the First Coal Fire:
Burning coal is much harder than burning wood. There is more care and work in building and maintaining a coal re than a wood re.
Anthracite is the best coal to burn, due to its long even burn with higher heat output and clean burn quality but is more difcult to manage
than Bituminous coal.
The size of coal is important. “Nut” coal sizes of 4 inches for Bituminous and 2¾ to 4½ inches for Anthracite coal are recommended.
Never use coal other than the sizes recommended. If the coal is too small it will smother the re and if it is too large the coal will not burn
well.
When burning Bituminous coal, start the re with wood (as described above). Always use dry kindling, as this will provide a hotter re
and add small pieces of wood until you get a good hot ember bed. At this point add a small amount of coal. When the coal is hot enough
to ignite, add small amounts at a time, so as not to smother the re. Keep in mind that Bituminous coal will require more maintenance as
this type of coal will produce more soot, requiring more frequent cleaning to prevent buildup.
Also make sure that the spin draft is wide open to establish the correct burn pattern. When adding coal to Bituminous res always add
coal to the center of the bed creating the cone effect. Bituminous coal is more volatile and adding coal to the center of the bed causes
the ames to drive off the volatile gases. Remember that no two installations and chimney set-ups are the same, so be prepared to
experiment until you achieve the desired results. Always allow enough air to the rebox and keep the damper open so that volatile gases
are properly burned. When adding fuel, remember to break up the cone with a poker if it has formed a crust, but be careful to avoid
mixing the coal as this can form clinkers. For overnight burn operations, follow the above instructions and adjust the chimney damper.
When burning Anthracite coal, start the re with wood (as described above). Add layers of coal making sure not to smother the re,
the third layer should be a little heavier, but should not to extend above 2 inches below the top of the brick in the rebox. Before
adding more fuel, be sure to leave a red spot in the center of the bed. This hot spot will help ignite the gases given off the new charge.
A deep charge will give a more even heat and a longer re. It may take up to a couple hours before the whole bed is fully ignited. When
the re is established and the home is becoming warm, you may adjust the damper. It may still take some experimenting to ensure
proper operation, as no two installations are the same. Once the coal bed has reduced to half its original depth it is time to add fuel to the
furnace. Open the fuel door, using a small rake or hoe pull the coals towards the front of the bed, trying not to disturb the re too much.
Next, add coal to the back, being careful not to seal off the top. Keep the ash pan cleaned out to ensure good airow. You may want to
start this banking process early in the evening before retiring or before leaving the home so that you may make proper adjustments after
the re is well established.
WARNING: It is unsafe to load any type of coal within 2 inches of the top of the rebrick. Load fuel carefully or damage may result.
NOTE: Do not burn coke, charcoal, highly volatile Bituminous coal, sub Bituminous, lignite or cannel coal (sometimes called channel coal
or candle coal). Never burn chemically processed logs, such as re logs, as their use is intended for replaces only. Please follow all
guidelines in this manual concerning wood and coal burning applications due to safety concerns and to maintain warranty coverage.
BURN WOOD AND COAL ONLY!

14
Disposal of Ashes:
Heat resistant gloves are recommended. In order to remove ashes from your Fire Chief Furnace, remove the ash pan from the furnace
and dump the ashes into 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 metal container until all cinders have thoroughly cooled.
Remove the ashes from your Fire Chief Furnace at least once a day, or as often as necessary to ensure the ashes do not accumulate to
the height of the grates. If ash build-up occurs at grate level, it will cause premature failure of the grate system, voiding the warranty on
the grates. Unacceptably high temperatures will result because the ashes have restricted the ow of cooling air beneath the grates. This
ow of air was designed to not only cool the grates, but to also provide warmed air for better combustion. If the ash level is improperly
maintained the rebox will be starved of combustion air, greatly reducing the efciency and heat output of your Fire Chief Furnace.
CAUTION: HOT SURFACES. KEEP CHILDREN AWAY. DO NOT TOUCH DURING OPERATION.
IMPORTANT: FOR TECHNICAL SUPPORT OR CUSTOMER SERVICE
ISSUES, DO NOT RETURN TO THE DEALER (THE DEALER DOES NOT HAVE
REPLACEMENT PARTS), CALL 1-800-875-4788.
Creosote Formation and Need for Removal:
When wood is burned slowly, it produces compounds in exhaust smoke which combine with expelled moisture to form creosote. The
creosote vapors condense in the relatively cooled chimney ue of a slow burning re. As a result, creosote residue accumulates on the
ue lining. When ignited, this creosote makes an extremely dangerous re in the chimney. The chimney connector and 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 risk of a chimney re.
Creosote Prevention:
To help reduce the formation of creosote within the ue, ALWAYS BURN DRY, SEASONED WOOD. Dry wood burns hotter, allowing ue
gases to maintain temperatures above 212°F which should reduce the quantity of creosote in the chimney. If the ue gas temperature
falls below 212°F, condensation occurs causing creosote formation and accumulation within the chimney.
As an added precaution, periodic chimney inspections are recommended during the heating season to determine if creosote formation
has occurred. For safety and efciency, it is recommended that the chimney system be inspected and cleaned prior to each heating
season.
Chimney Fire Warning:
In the event of a chimney re, take the following actions immediately:
• Activate and toss a Chimfex™ Dry Chemical Chimney Fire Extinguisher into the rebox.
• Close the ash drawer, fuel door and spin drafts.
• Alert entire household and prepare to evacuate if necessary.
• Call your local re department.

Power Failure:
In case of power failure, to prevent your Fire Chief Furnace from over-heating and causing damage to the electrical components, do NOT
add more fuel (coal or wood) to the rebox.
There is no warranty on electrical components damaged due to power failure.
NOTE: OVER-FIRING OR DELIBERATE ABUSE CAN EASILY BE DETERMINED UPON INSPECTION AND WILL VOID THE
WARRANTY.
Always keep your wood covered year round. Dry wood will produce higher BTU output and a longer burn time. Refer to the nameplate
on furnace for additional information.
WARNING: RISK OF FIRE
• Do not operate with the ue draft exceeding .08 water column inches (19.9 Pa).
• Do not operate with fuel loading door or ash removal drawer open.
• Do not store fuel or other combustible material within marked installation clearances.
• Inspect and clean ues and chimney regularly.

Problem: Odor detected in home during initial ring.
• There is an oily lm that remains
on the steel after the manu-
facturing process. Firing the
furnace has raised the tempera-
ture of the re box to a level that is
sufcient to vaporize the residue.
• The odor should disappear after a few hours of usage.
