FIRE CHIEF OUTDOOR FURNACE MANUAL
MODEL: FCOS1800D, FCOS2200D
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 rulings 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 installed 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 30 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 MORE 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 (1800 model) and 34”
(2200 model). In addition, the heat exchanger is lined with rebrick to ensure many years of energy efcient service.
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 heavy-duty cast iron grates aid in convenient ash removal and reduce maintenance; 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 it burns itself out.

Furnace Clearances and Operation
Before beginning your installation, consult with local authorities regarding the codes governing all such installations. DO NOT connect
your Fire Chief Furnace to any 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 – do not place the furnace more than 30 feet from
the house. The furnace must be connected to a grounded electrical circuit with access to a backup generator (2000 watt minimum). If
locating the furnace more than 10’ from the home, a minimum of 6’ of Class “A” HT 2100 All Fuel 6 inch Chimney Pipe is required. 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 for wood and coal burning applications
• Heat Duct = 6 inches for the rst 16 inches from the back of the furnace, and 3 inches beyond
Maintain the “10/2 Rule” for the ue, which says the ue must be 2 feet higher than any part of the building or peak of the roof within a
horizontal distance of 10 feet. The 2 foot height does not include the cap. See diagram below.
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 high-
temp 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 product. DO NOT USE GALVANIZED OR BLACK PIPE TO VENT YOUR FURNACE.

Once you have met 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. 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.
You must install the wall thermostat for the furnace to operate. When the wall thermostat calls for heat, the draft motor will engage,
allowing combustion air to ow into the rebox. This causes a hotter re, increasing the heat in the heat chamber. When the home
reaches the selected temperature on the wall thermostat, it will disengage the draft motor and the re in the rebox will reduce to a low
burn until the thermostat calls for another heat cycle. 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. This process is called a heating cycle.
IMPORTANT: FOR TECHNICAL SUPPORT OR CUSTOMER SERVICE
ISSUES, DO NOT RETURN TO THE DEALER (THE DEALER DOES NOT HAVE
REPLACEMENT PARTS), CALL FIRE CHIEF AT 1-800-875-4788.
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.

INSTALLING THE ANCHOR PLATE:
Note: Check with your dealer for the anchor plate that connects to Class A HT2100 chimney. IMPORTANT: BEFORE YOU FOLLOW
THE NEXT STEPS, ENSURE THE ANCHOR PLATE YOU RECEIVE MATCHES YOUR CHIMNEY PIPE, AS CHIMNEY PIPE IS NOT
GENERIC AND WILL NOT INTERCHANGE.
1. Using the diagram below as a guide, caulk the bottom of the anchor plate around the center pipe shaft.
2. Install the anchor plate to the top of your furnace using four #10 3/4” galvanized screws with rubber gaskets.
3. Install the chimney pipe to your outdoor furnace.
4. After all the chimney components are installed including the cap, follow the diagram below to caulk around the chimney pipe
as well as around the outer edge of the anchor plate.
Chimney Location and Clearances:
Requires Class “A” HT 2100 All Fuel 6” Chimney
The furnace requires a minimum of 6 feet of chimney. When positioning the furnace, 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,
PLACE A LINE OF 1
4DIA HIGH TEMPERATURE
SILICONE CAULK ON CHIMNEY ADAPTOR AS
SHOWN BY DASHED LINES
Place a line of high temperature caulk
(1/4 inch diameter) on the chimney
adaptor as shown with dashed line.

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. If the chimney is closer than 10 feet from the peak of the roof, 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. The furnace must be placed on a level,
non-combustible surface or 4 foot x 8 foot concrete pad. Do not level from top of furnace. The front is 1/2” taller than the back for water
run off. See diagram below.
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 efcient 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.
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 as well as producing
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 (THE DEALER DOES NOT HAVE
REPLACEMENT PARTS), CALL FIRE CHIEF AT 1-800-875-4788.

• 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, lower the temperature on the thermostat; reduce the spin draft to allow less airow into the rebox;
and/or use less fuel (wood or coal).
• 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.
