conditioning your Stove

Cast iron is extremely strong, but it can be broken with 

a sharp blow from a hammer or from the thermal shock 

of rapid and extreme temperature change.
The cast plates expand and contract with changes in 

temperature. When you first begin using your Defiant, 

minimize thermal stress by letting the plates adjust 

gradually during three or four initial break-in fires follow-

ing Steps 1-3 below.

Non-catalytic wood burning

Burn only solid wood in the Defiant, and burn it directly 

on the grate. Do not elevate the fuel. Do not burn coal 

or other fuels. 

The bypass damper must be open when starting a 

fire or when refueling.

  

Do not use chemicals or fluids to start the fire.  Do 

not burn garbage. Never use flammable fluids such 

as gasoline, gasoline type lantern fuel, kerosene, 

charcoal lighter fluid, naptha, engine oil or similar 

liquids to start or “freshen up” a fire in this heater. 

keep all such liquids well away from the heater 

while it is in use. 

1.  Open the stove bypass damper, and open the prima-

ry air control fully.
2.  Place several sheets of crumpled newspaper in the 

stove. Place six or eight pieces of dry kindling split to a 

finger-width size on the paper. On the kindling, lay two 

or three larger sticks of split dry wood approximately 

1-2” (25-51 mm) in diameter. (Fig. 37)
3.  Light the newspaper and close the door.  Gradu-

ally build up the fire by adding a few 3-5”  (80-120 mm) 

diameter pieces of split firewood.  

if this is one of the 

first few “break-in” fires, let the fire burn brightly, 

and then let it die out. 

 

Use the air control Settings

 that work best for you

No single air control setting will fit every situation.  Each 

installation will differ depending on the quality of the 

fuel, the amount of heat desired, and how long you wish 

the fire to burn; outdoor air temperature and pressure 

also affect draft.   
The control setting also depends on your particular 

installation’s “draft,” or the force that moves air from the 

stove up through the chimney.  Draft is affected by such 

things as the length, type, and location of the chimney, 

local geography, nearby obstructions, and other factors. 

See Page 27 for details on how the installation affects 

performance.
Too much draft may cause excessive temperatures in 

the Defiant, and could even damage the stove. On the 

other hand, too little draft can cause backpuffing into 

the room and/or the “plugging” of the chimney.
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 or low heat output.
In some newer homes that are well-insulated and 

weather-tight, poor draft may result from an insufficient 

air supply in the house.  In such instances, an open 

window near the stove on the windward side of the 

house can provide the combustion air supply needed.  
Another option for getting more combustion air to the 

stove is to duct air directly from outside to the stove.  In 

some areas provisions for outside combustion air are 

required in all new construction.
The Defiant is equipped to deliver outside air for com-

bustion and outside air kit #3265 is available.   
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.
