SAVE THESE INSTRUCTIONS
Congratulations! You have selected the nest quality outdoor wood and coal burning furnace, manufactured with pride in the
USA. Please take a few moments to carefully read the owner’s manual. By taking the time to familiarize yourself with your
new Fire Chief Furnace, you will be able to look forward to years of trouble-free, dependable service.
Installation:
• First, check local codes. The installation must comply with all local regulations and requirements.
• This furnace is an outdoor hot air furnace and must not be altered in any way.
• This furnace requires a back-up electric generator, 2000 watts minimum, in case of power failure.
• Always have a properly installed and functioning smoke detector in your home.
• To prevent accidental injury, do not allow anyone who is unfamiliar with the furnace to operate it.
• Spend time familiarizing yourself with your Fire Chief Furnace, especially the different settings and the effects they
have on burn patterns. It is impossible to predict how each setting will affect your furnace, due to variations in
conditions, fuels, and temperatures.
• When making plans to install your outdoor furnace, the rst thing you need to think about is the placement of the
unit. Although you can install the Fire Chief Furnace up to 25 feet from the home, a much shorter distance is
recommended to provide better airow. The furnace has been tested for clearance of 31 inches from the home;
this would give maximum airow and provide the highest efciency.
Transportation Damage
Every effort has been made to ensure that your Fire Chief Furnace will arrive in perfect condition. Any visible damage should
be noted on the freight bill at the time of delivery. If upon unpacking your furnace, you nd damage has occurred during
transit, notify your dealer immediately. Your dealer will advise you what actions must be taken to correct the problem.

General Information
ALWAYS KEEP YOUR WOOD COVERED YEAR ROUND; DRY WOOD WILL PRODUCE HIGHER BTU OUTPUT AND LONGER BURN
TIMES.
The Fire Chief Furnace is an airtight central solid fuel outdoor furnace engineered to accommodate the heating requirements of the
average sized home, even during winter’s coldest months. It is constructed of high grade, heavy gauge steel and is continuously welded
to assure the utmost in structural strength. The insulated rebox will accommodate a log up to 28 inches in length.
The design of the secondary combustion chamber increases fuel efciency by creating a “secondary burn” of smoke and wood gases
before they are vented up the chimney. By sending the gases back through the secondary combustion chamber, less fuel is wasted, the
furnace burns at a higher efciency, and for longer burn times.
The cast iron door is custom tted to provide an airtight seal, greatly extending the burn time and ensuring maximum efciency in fuel
consumption. The insulated wrap-around sides are designed for maximum heat transfer.
For total comfort and convenience, a thermostatically controlled 1800 CFM circulation blower system has been installed. The blower
draws the cold air from the home, across the heat chamber before going through the hot air duct and returning the warm air to your home.
This fully automatic blower furnishes rapid heat disbursement to your home, minimizing recovery time. Average burn time per load of
fuel is 6 to 12 hours depending on wood or coal type and condition, desired temperature within the home and amount of fuel. We have
incorporated all of these features as standard equipment, offering you the most efcient, durable and affordable appliance possible.
Abnormally cold weather could reduce the burn time.
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 certied in accordance with
a nationally recognized safety standard, and within clearances specied on Fire Chief Furnace 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 qualied installer
should perform the installation.
This is a wood and coal burning furnace – it cannot be turned “off and on” to control the furnace temperature like gas or electric furnaces.
Once the re is established, it has to burn until the fuel load is consumed.

Furnace Clearances and Installation
Before beginning your installation, consult with local authorities regarding the codes governing all such installations. DO NOT connect
your Fire Chief Furnace to a ue that is servicing ANY other appliances.
The Fire Chief Furnace may be placed outdoors or indoors. If outdoors, it must be placed on a level, non-combustible base, preferably
a 4’ x 8’ concrete pad, as close to the home as clearances to combustibles permit – but do not place the furnace more than 25 feet from
the house. The furnace must be connected to a grounded electrical circuit with access to a backup generator (2000 watt minimum). If
installing indoors, your furnace must be placed on a non-combustible oor. Air for combustion must be provided into the room where the
furnace is located. Allow air free access to furnace for combustion and ventilation.
Maintain the following clearances:
• Front = 48 inches
• Rear = 31 inches
• Sides = 12 inches
• Heat Duct = 6 inches for the rst 16 inches from the back of the furnace, and 3 inches beyond
Once you have taken into consideration the local requirements governing the installation and positioning of the furnace, install the
Electrical Control Kit. Open the Electrical Control Kit and conrm that all items were shipped with your Fire Chief Furnace. IMPORTANT:
ENSURE THE POWER CORD IS PLUGGED INTO A GROUNDED ELECTRICAL SUPPLY. The fan limit control is factory pre-set at
160° as the “ON” temperature setting and 100° as the “OFF” temperature setting. This means when the heat chamber reaches 160°, the
blower will turn on; when the chamber cools, the blower will turn off.
IMPORTANT: FOR TECHNICAL SUPPORT OR CUSTOMER SERVICE ISSUES,
DO NOT RETURN TO THE DEALER, CALL FIRE CHIEF AT 1-800-875-4788.

NOTE: When installing blower housing to the back of the furnace, we suggest that you support the bottom of the blower housing
approximately 6 ¼ inches from ground level to allow for easier mounting of the blower housing cover.
Chimney Pipe and Anchor Plate:
Class “A” HT 2100 All Fuel 6 inch Chimney Pipe is required for optimum performance and must maintain a 2 inch clearance from
combustibles. The Fire Chief Furnace will ship with an anchor plate and four #10 ¾” galvanized screws with washers and gaskets to
match the chimney your dealer supplies. If the anchor plate provided with your furnace does not t the chimney your dealer has in stock,
please call our toll free number, 1-800-875-4788 for assistance.
IMPORTANT: Please keep in mind that different chimney manufacturers’ pipe will not interchange with other brands. A tube of hightemp silicone caulk is included with your furnace. Before using the silicone to install the anchor plate to the top of your Fire Chief
Furnace, ensure the chimney you purchased will t the anchor plate.
Guy wire brackets are attached to the sides of the Fire Chief Furnace. A heavy gauge of stainless steel wire can be purchased from your
dealer or at a local hardware store to use as guy wire to help support your chimney. Attach the appropriate chimney pipe lengths to the
adaptor plate nishing with a chimney cap. IMPORTANT: Your furnace requires its own chimney system and cannot share a ue with any
other appliance. DO NOT USE GALVANIZED OR BLACK PIPE TO VENT YOUR FURNACE.

Chimney Clearances and Installation:
Requires Class “A” HT 2100 All Fuel 6” Chimney.
The furnace requires a minimum of 6 feet of chimney. Maintain the “10/2 Rule” for the chimney – 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 of the measurement
increases. Once this measurement reaches 10 feet, this height on the chimney is your base height. The chimney must be 2 feet taller
than the base height and the chimney must be 2 feet higher than the peak of the roof. The 2 feet above the base height does not include
the cap. See diagram below.

LEVEL CONCRETE PAD
Level Concrete Pad
By denition, “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,
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-inch water column draft. The ue draft can be measured with the use of a draft gage or manometer.
Bypass Damper:
The bypass damper has several purposes: starting the re, improving the efciency, and cleaning the chimney. When starting a re in the
Fire Chief Furnace, you must pull the rod out for a stronger draft during ignition. Once the re has started, close the bypass, which allows
the secondary combustion chamber to engage, increasing the furnace’s operation to peak efciency. If the bypass rod is not closed
during operation, the furnace’s efciency will be greatly reduced, allowing the heat to escape up the chimney. Finally, when cleaning the
chimney, the rod must be pulled out to allow any build-up in the chimney to fall into the rebox.
THIS UNIT IS NOT TO BE CONNECTED TO A CHIMNEY FLUE THAT SERVES ANOTHER APPLIANCE.
7
Wood Storage and Care:
KEEP WOOD COVERED AT ALL TIMES. This cannot be over-emphasized. Wood stored/stacked, uncovered, exposed to rain and snow
has a higher moisture content, causing the formation of creosote, excess smoke, and it takes longer to ignite and produces poorer res
with lower sustained BTU output. Unseasoned wood ends up costing more in time trying to achieve and maintain proper temperatures
in the rebox, while using more wood with less heat output. Covering the woodpile will keep it dry and offer you the hottest res with the
greatest BTU output. If you store the wood near your furnace, be sure to maintain proper clearance from the furnace to prevent a re
hazard. DRY WOOD WILL PRODUCE HOTTER FIRES AND INCREASE BTU OUTPUT.
IMPORTANT: FOR TECHNICAL SUPPORT OR CUSTOMER SERVICE ISSUES,
DO NOT RETURN TO THE DEALER, CALL FIRE CHIEF AT 1-800-875-4788.
The Initial Firing:
Do NOT connect the furnace to your ductwork at this time. Build a small re – DO NOT ll the rebox to full capacity during the initial
ring. Your new furnace has a protective coating of oil or paint on the surface, which could produce smoke or odors during the initial ring
and will burn off. Allow adequate ventilation during this initial, break-in ring to let any odors escape. This initial ring also allows the
metals to cure. After successfully completing the initial ring, you are ready to attach the hot air duct and cold air return to complete your
installation. See diagram below.

Furnace Installation Reminders
• Installation is to be performed by a qualied installer.
• Always consult local building inspectors for codes concerning the installation of your furnace.
• Always have access to a backup generator, 2000 watt minimum.
• Use Class “A” HT 2100 All Fuel 6 Inch Chimney for your Fire Chief Furnace.
• Never use galvanized pipe in your ue connection.
• Inspect the ue periodically for structural integrity.
• Clean the ue regularly to prevent creosote accumulation.
• Never use chemicals or gasoline to start or maintain your re.
• Never burn garbage, oil, trash, or gasoline in your furnace.
• Never leave the fuel door or ash drawer open during operation.
• Remove ashes on a daily basis, before ashes reach the grates, to ensure proper air ow.
• Never use wet, unseasoned wood or wood exposed to a recent rainfall. Doing so causes a rapid accumulation of hazardous
creosote, which is a proven cause of ue res.
• Never burn plastics, wood products containing glue, or wood that has been treated with chemical preservatives in your
Fire Chief Furnace. The combustion of these substances may release harmful, toxic gases.
• NEVER UNPLUG THE FURNACE FROM THE POWER SOURCE. THIS WILL CAUSE THE FURNACE TO OVERHEAT. If it
is too warm in the house, reduce the spin drafts to allow less airow into the rebox; and/or use less fuel.
• Never leave the ash drawer or fuel door open in an attempt to regulate the re. This will overheat the furnace and void
the warranty.
• Do not connect this unit to a chimney ue serving another appliance.
• Refer to nameplate on furnace for additional information.
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.
DANGER: Risk of Fire and Explosion. Do not burn garbage, gasoline, naphtha, engine oil, or other ammable liquids/inappropriate
materials.

Hot Air Duct and Cold Air Return Installation:
Included with your Fire Chief Furnace:
• Two 10 inch starter collars
• One 12 inch starter collar
If using 10 inch insulated hot air ex duct, it is for indoor use only. Outside the house, you must use 10 inch galvanized pipe, wrapped
with weatherproof UV-jacketed insulation for protection from the sun’s UV rays. The 12 inch return air may be galvanized pipe. The
12 inch return air must be attached to the home so as not to pressurize the home. The warm air supply duct should be constructed of
materials with a minimum temperature rating of 250° Fahrenheit.
NEVER reduce the 10 inch hot air or 12 inch return air, as this will affect the air ow and the furnace will 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 .02 water column inches, while developing air
velocities of 600 feet to 1,000 feet per minute in the main trunk duct and 400 feet to 600 feet per minute at the registers. The heat outlet
should never be less than 10 inches round or 79 square inches.
The Fire Chief Furnace must be installed with a cold air return system. The system must be a minimum of 12 inches to readily transfer
the cold air back to the furnace. If desired, a cold air lter box may be constructed with a minimum opening of 113 square inches. An
optional air lter box (FCOSFB) is available for purchase at Fire Chief. Please call 1-800-875-4788 for details.
A basement window is an excellent location for running the hot air duct as well as the for the cold air return. The cold air return is an
integral part of the system and must be used when installing the furnace. Failure to use cold air return will pressurize the home causing
the furnace to not work properly. If a basement window is not available, you may access the home through a window, wall, or crawl
space for both the plenum and air return.
Burying Ductwork:
DO NOT BURY FLEXIBLE DUCT.
To bury the ductwork, use schedule 40 or 80 PVC or black plastic DUAL WALL CULVERT PIPE with smooth inner walls. Dig a trench to
accommodate both the heat duct and the return air duct. The trench must be a minimum of 24 inches deep. To further ensure efciency,
minimize heat loss, and prevent moisture formation, line the trench with 1 inch pink Styrofoam insulation sheeting on the sides and
bottom of the trench. The duct run should not exceed 25 feet. If the run exceeds 25 feet, you run the risk of reducing the furnace’s
efciency and airow.
DO NOT USE FLEXIBLE HOT AIR DUCT INSIDE PVC OR CULVERT PIPE.
ALWAYS KEEP YOUR WOOD COVERED YEAR ROUND. DRY WOOD WILL PRODUCE MORE HIGHER OUTPUT AND A LONGER
BURN TIME.

The diagram below shows typical installations through a basement window, crawl space, or wall. Notice that the heat duct and return air
duct do not contain any 90° elbows. The use of 45° or less is advised for proper air delivery.
IF 10 INCH FLEX DUCT IS USED, IT MUST NOT BE EXPOSED TO THE OUTDOORS. IT IS FOR INDOOR USE ONLY.
WARNING: RISK OF FIRE! IF USING FLEXIBLE DUCT FOR INDOORS, DO NOT USE ANYTHING OTHER THAN 250° F-RATED
FLEX DUCT!
IMPORTANT: FOR TECHNICAL SUPPORT OR CUSTOMER SERVICE ISSUES,
DO NOT RETURN TO THE DEALER, CALL FIRE CHIEF AT 1-800-875-4788.
TYPES OF INSTALLATIONS:
Your Fire Chief Furnace is designed to be a supplemental or central heating source for your home. This wood/coal burning furnace may
be installed in parallel with a properly operating electric, gas, or oil-red central furnace that is listed or certied in accordance with a
nationally recognized safety standard within installation clearances as specied on the Fire Chief Furnace nameplate. When in a parallel
installation the static pressure of the central furnace plenum may not exceed .15 water column inches, and the maximum setting on
central furnace limit switch is 182° F. With your furnace in an “Interconnection Arrangement” the wood or coal-burning furnace should be
upstream from the central furnace. The Fire Chief Furnace warm air supply should never be connected to the return air for the central
furnace. A QUALIFIED INSTALLER SHOULD PERFORM THE INSTALLATION.
CENTRAL DUCT CONNECTIONS: A qualied professional should do the installation. Maximum run should be 25 feet. A duct run in
excess of 25 feet will greatly restrict the air ow and heat output, therefore is not recommended. When connecting the Fire Chief Furnace
to a central duct system, avoid 90° elbows. As with any furnace, the more turns and branches in the ducting limit the airow delivery. DO
NOT USE FLEX DUCT OUTSIDE.
Run 10 inch insulated galvanized hot air duct from the outside furnace through a window or wall of the house. Once inside, you may use
250º Fahrenheit rated insulated exible hot air duct to connect to the central duct system for the home. When using exible duct inside
the home, it must be pulled tight with no offsets or elbows. Connect the duct with a 45° elbow or at an angle so the hot air from the Fire
Chief Furnace is delivered down stream. This will ensure proper airow into the duct system. Avoid delivering the hot air through the air
conditioning coil, as this will cause an obstruction, reducing the amount of heat output. DO NOT REDUCE THE SIZE OF THE HOT AIR
DUCT. As with any furnace, longer runs and more turns and branches in the ducting greatly reduce the airow and heat output. Use of
90° elbows is not recommended.
The 12 inch cold air return duct must run to the house to prevent pressurization of the home. Failure to connect the cold air return will
cause the furnace not to operate. NEVER REDUCE THE SIZE OF THE RETURN. Reducing the size of the cold air return will restrict
the hot air ow and put excess pressure on the blower motor. You may terminate the cold air return where you enter the house. This will
provide adequate circulation within the home. See diagram.

duct and the cold air return duct may be accessed through the oor in a mobile or modular home. In a mobile home with a down draft
furnace, do not attach the hot air duct from the Fire Chief Furnace to the hot air plenum, doing so will cause the heat to rise through the
central furnace instead of going through the duct work. Split the hot air supply for the Fire Chief Furnace by using a “Y” and install one
branch into each of the hot air ducts. Be sure both are pointing downstream. See diagram.

NO DUCT WORK INSTALLATION CONNECTION: A qualied professional should do the installation. Cold air return must be
installed in all cases, even those without ductwork. When there is no duct system to connect to the hot air ex duct, keep in mind:
• You must separate the hot air duct from the cold air return. Ideally, locate each at opposite ends of the home. If you don’t, the
air will not ow evenly throughout the home. This method will work well on homes built on concrete slabs and help create a
good airow.
• In homes with a basement, you may run the hot air duct into the basement and pull the cold air return from the main oor, this
will create a perfect air ow, since hot air rises. The cold air return must be connected, even if the home does not have
ductwork. If you don’t connect the cold air return, the furnace will not be able to heat the home. See diagram.

Outside Combustion air may be necessary for an indoor installation 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 alleviates 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.
CAUTION: HOT SURFACES. KEEP CHILDREN AWAY. DO NOT TOUCH DURING OPERATION.
BURN WOOD AND COAL ONLY!
General Operation:
First Wood Fire:
Check to make sure the spin drafts are wide open to allow oxygen into the rebox.
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
and push the bypass rod all the way in. Within 30 to 40 minutes, adjust the spin draft 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 classied as having airtight construction. This type of design
should enable you to experience an average burn time between 6 and 12 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 signicantly 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, always pull the bypass rod all the way out before opening the fuel door, 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 reduce 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
efciency by adding fuel in amounts needed to maintain comfortable temperatures in your home.

IMPORTANT: FOR TECHNICAL SUPPORT OR CUSTOMER SERVICE ISSUES,
DO NOT RETURN TO THE DEALER, CALL FIRE CHIEF AT 1-800-875-4788.
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 difcult 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 control 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 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. 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 with the spin draft 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. At this point pull out the bypass rod and open the spin draft. This will
allow the re to burn off the accumulated gases. 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 drawer cleaned out
to ensure good airow. 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: 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 wax or chemically processed logs, such as re logs as their use is 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!
Fuel Recommendations:
For the FCOS1600D model, heat resistant gloves are recommended when loading the furnace. Only use 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; this allows the wood
to season faster. If wood is stored outdoors, it should be completely covered year round to protect it from moisture and exposure to the
elements. Use extreme caution when opening the ash drawer and fuel door during operation, temperatures can exceed 300° F. Wait at
least 10 seconds after releasing the rst latch, then proceed to the fully open position. The dual latch system has been incorporated as a
safety feature, which was designed to reduce the possibility of gaseous ignition. Heat resistant gloves are recommended when opening
the fuel door, regulating the spin draft or emptying the ash pan.
14
DISPOSAL OF ASHES:
Heat resistant gloves are recommended. Remove the ash drawer 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 grate. If ash build-up occurs at grate level, it will
cause premature failure of the grate. Unacceptably high temperatures will result because the ashes have restricted the ow of cooling
air. This ow of air was designed to not only cool the grate, but to also to provide warmed air for better combustion. If the ash level is
improperly maintained the rebox will be starved of combustion air, greatly reducing the efciency and heat output of your Fire Chief
Furnace.
ALWAYS KEEP YOUR WOOD COVERED YEAR ROUND. DRY WOOD WILL PRODUCE A HIGHER BTU OUTPUT AND A LONGER
BURN TIME.
HEAT DUMP AND FUSE LINK SYSTEM:
The Fire Chief Furnace has a patented automatic safety feature, the Heat Dump Release System. In the case of a power failure, the heat
dump release will open the spring-loaded lid when the internal furnace temperature reaches 536° F. The heat sensitive fuse link, located
within the top of the heat chamber, causes the lid to open, allowing the excess heat to escape. This patented safety feature is designed
to activate before any extreme heat can damage the furnace.
In the case of a power failure, connect your Fire Chief Furnace to a generator immediately. If the heat dump release lid should open, do
not continue to burn the furnace. DO NOT UNPLUG THE FURNACE. Close the spin draft controls and DO NOT add fuel (either wood
or coal), which will allow the re to die. Pull out by pass rod. After the electricity is restored, replace the fuse link before resuming normal
operation.
REPLACING THE FUSE LINK: Remove the hex nut on top of the release lid and pull the bolt down through the lid. Remove the
separated fuse link pieces and connect the new fuse link to the shaft inside the furnace heat chamber. Connect the other end of the
fuse link to the bolt that goes through the lid. Feed the bolt through the lid and replace the hex nut onto the bolt on top of the lid. As a
precaution, always have a replacement fuse link on hand.
WARNING: Never disengage the patented Heat Dump Fuse Link feature. This will void all warranties. Never put anything on top of the
release lid. The area must be kept free of any obstructions. A visual inspection by factory personnel can easily determine if the proper
steps were taken if a furnace over-heats. If the furnace is found to be deliberately improperly used, all warranties will be void.

One replacement fuse link was included in the hardware pack for your furnace.
15
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 Reduction:
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 formation 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 efciency, it is also recommended that the chimney system be inspected and cleaned prior to each heating
season.
Power Failure:
In case of power failure, to prevent your Fire Chief Furnace from over-heating and causing damage to the electrical components, follow
these steps:
• Ensure that the bypass rod is pulled out, allowing heat to go up the chimney.
• Close the spin damper control on the ash drawer and fuel door.
• Do NOT add more fuel (coal or wood) to the rebox.
There is no warranty on electrical components damaged due to power failure.
CAUTION:
• INSPECT FLUE PIPES, FIREBOX, STOVE PIPE, CHIMNEY AND DRAFT BLOWER JOINTS AND SEALS REGULARLY TO
ENSURE THAT SMOKE AND FLUE GASES ARE NOT DRAWING INTO, AND CIRCULATED BY THE
AIR-CIRCULATION SYSTEM.
• CLEANING OF THE FIREBOX, STOVE PIPE, CHIMNEY AND DRAFT BLOWER (IF USED), IS ESPECIALLY IMPORTANT
AT THE END OF THE HEATING SEASON TO MINIMIZE CORROSION DURING THE SUMMER MONTHS CAUSED BY
THE ACCUMULATED ASH.
• Do not use chemicals to start the re.
• Do not burn garbage, gasoline, naphtha, engine oil, or other ammable liquids/inappropriate materials.
16
Maintaining Your Furnace:
At the beginning of each heating season, take time to thoroughly check your furnace and chimney system. Make sure there are no
leaks where the metal panels are joined or at the caulk lines. Should you nd a leak, high-temp silicone will correct the problem. Check
the door for signs of rust. Should rust develop, lightly sand, with sandpaper or steel wool, the surface and follow up with black, high
temperature paint to keep the door looking new. Check the gaskets, if they are frayed and burnt, replace the gasket. Check the chimney
pipe for signs of creosote formation, if you nd creosote, thoroughly clean the chimney system replacing the chimney cap securely so
rain or snow does not run down the chimney into the rebox. If the cap is removed for any length of time when the furnace is not in use,
cover the pipe so no moisture gets into the rebox. Check the chimney cap for holes or loosened connections, replace and secure as
necessary. Check the heat duct and cold air return to be sure they have not become loose or been damaged. If so, tighten or replace as
needed. Check ductwork for any air leaks. Remove any accumulated ashes at the end of the season. By following these procedures,
your furnace will provide many years of trouble-free service.

the furnace not providing enough
heat.
• Inadequate insulation of the
home.
• Furnace size is inadequate for
your home.
• Fueling furnace with wet or
unseasoned wood.
• Outside air is being pulled into
the return air duct, reducing the
heat output in the home..
• Refer to information in the manual relating to the proper ducting
procedures or consult your local heating and cooling contractor.
• Check and replace lter.
• Increase height of chimney (refer to “10/2 Rule” on page 4.) This will
help the furnace to achieve more efcient and hotter temperatures.
• Provide additional insulation.
• Consult a professional to determine correct sizing.
• Completely avoid using if at all possible. If circumstances
necessitate the use of wet or unseasoned wood, then fuel the
furnace with smaller loads.
• Inspect return air duct from the blower housing to the home, seal
any openings with aluminum duct tape.
Problem: Heat dump lid on top of furnace has opened.
3.
Possible Causes:
• Power failure.

• Do not attempt to overload the furnace.
26
15.
Problem: Down draft on chimney caused by one or more of the following.
Possible Causes:
• Flue has a cold spot which
inhibits exhaust discharge from
rising properly.
Remedies:
• This problem may occur in factory built ues because the insulation
has settled or a seam has ruptured. In masonry ues, mortar loss
may be causing seepage of cooler outside air into the stack. Check
entire ue for structural integrity and leakage. Correct or repair as
needed, or replace or re-line the chimney.
