Defiant Woodburning Stove

High-Efficiency Wood Burning 

with Catalytic Combustion 

A Defiant leaves the factory with the combustor in-
stalled.
In the United States, it is against the law to operate this 
wood heater in a manner inconsistent with operating 
instructions in this manual, or if the catalytic combustor 
is deactivated or removed. The components of the cata-
lytic combustion system in your Defiant work together to 
produce optimum conditions for secondary combustion.  
When the damper is closed, smoke travels through the 
catalytic element, which causes ignition of smoke at 
temperatures of 260°-315° C (500°-600° F), half the 
temperature normally required for unaided secondary 
combustion. 
The catalytic element is a ceramic “honeycomb” coated 
with the catalytic material. The element is located in the 
secondary combustion chamber, molded from a special 
high-temperature insulating refractory material.  The 
chamber provides the correct environment necessary 
for secondary combustion of the fuel (smoke).
Closing the damper exposes the smoke to the combus-
tor. If the combustor is at least 315° C (600° F), it will 
begin to burn the smoke.
Closing the stove damper may also reduce the draft, so 
to avoid putting out the fire or deactivating the combus-
tor, close the damper only when a fire is well-estab-
lished and the chimney is thoroughly warmed. When 
starting a fire, wait until the fire is well established and 
there is an ember bed of at least 76-102 mm (3-4”) 
before closing the damper.
Never kindle a fire with colored paper or paper that 
has colored ink or a glossy surface, and never burn 
treated wood, garbage, solvents, or trash.  All of these 
may poison the catalyst and prevent it from operating 
properly. Never burn cardboard or loose paper except 
for kindling purposes. Never burn coal; doing so can 
produce soot or large flakes of char or fly ash that can 
coat the combustor and cause smoke to spill into the 
room. Coal smoke also can poison the catalyst so that it 
won’t operate properly.  
In general, the fire must be sufficiently well-established 
to ensure that catalytic activity is initiated. When first 
starting a fire, a medium- to high- firing rate must be 
maintained until the stove, catalyst, and fuel are all 
stabilized at the proper operating temperatures, and the 
chimney is warmed.  
Even though it is possible for the fire to get quite hot 
within a few minutes after a fire is started, the combus-
tor may stop working or the fire may go out if the fire 
dies down immediately as a result of the damper being 
closed. Once the combustor starts working, heat gener-
ated by burning the smoke will keep it working.

things as the length, type, and location of the chimney, 
local geography, nearby obstructions, and other factors. 
See Page 20 for details on how the installation affects 
performance.
Too much draft may cause excessive temperatures in 
the Defiant, and could even damage the combustor.  
On the other hand, too little draft can cause backpuffing 
into the room and/or the “plugging” of the chimney or 
combustor.
How do you know if your draft is excessively high or 
low?  Symptoms of too much draft include an uncontrol-
lable burn or a glowing-red stove part. Signs of weak 
draft are smoke leaking into the room through the stove 
or chimney connector joints, low heat, and dirty glass.
In some newer homes that are well-insulated and 
weather-tight, poor draft may result from insufficient air 
in the house.  In such instances, an open window near 
the stove on the windward side of the house will provide 
the fresh air needed.  
In some areas provisions for outside combustion air 
are required. Refer to section 2 of Document J which 
requires an outside air vent for appliances with power 
outputs over 5 kW. Always refer to national and local 
codes to determine your specific requirements.
With an optional outside air adapter, No. 1904, your 
Defiant will accept a duct to deliver outside air for com-
bustion.  
When first using the stove, keep track of the air control 
settings. You will quickly find that a specific setting will 
give you a fixed amount of heat. It may take a week or 
two to determine the amount of heat and the length of 
burn you should expect from various settings.
Most installations do not require a large amount of 
combustion air, especially if adequate draft is available.  

Do not for any reason attempt to increase the firing 
of your heater by altering the air control adjustment 
range outlined in these directions.

Use the following air control settings as a starting point 
to help determine the best settings for your installation.  
Each is described as a fraction of the total distance the 
lever may be moved from right to left.
