4. If your Defiant has been broken-in previously us-
ing Steps 1-3, continue to build the fire gradually. Add
larger wood with a diameter of 3-4” (75-100 mm). Con-
tinue adding split logs of this size to the briskly-burning
fire until there is a glowing ember bed at least 3” (75
mm) deep. (Fig. 34) A good ember bed is necessary for
proper functioning of the catalytic system and may take
an hour or more to establish.
Do not break the charcoal into very small pieces or
pound or compress the charcoal bed.
It is important that air can circulate through the charcoal
bed during the burn. Larger pieces of charcoal allow
more air to circulate under the wood, resulting in the
fire reviving more quickly. (Fig. 35)
For best results when refueling, wear long-cuffed stove
gloves to protect your hands and forearms, add fuel
while the stove still has plenty of glowing embers to
re-kindle the fire, and include some smaller pieces of
wood in the new fuel load to help the stove regain its
operating temperature quickly. Use this sequence as a
guide to successful refueling:
1. Open the damper.
2. De-ash the stove as described above. Open the
ashdoor and check the level of ash in the ash pan.
Empty the pan if necessary and replace it in the
stove. Close the ash door.
3. Open the griddle, load the wood (smaller pieces
first), and close the griddle.
4. Close the damper.
5. When the surface temperature reaches 450°F.
(230°C), adjust the air control for the amount of heat
you desire.
NOTE: If the remaining charcoal bed is relatively thick
and if your fuel is well seasoned, it is possible to add
fresh fuel (smaller pieces first), close the door and
damper, and reset the primary air thermostat for the
desired heat output.
WARNING: Operate your Defiant only with the
doors either fully open or fully closed.
CAUTION: The Defiant will be hot while in opera-
tion. Keep children, clothing and furniture away.
Contact may cause skin burns.
DO NOT OVERFIRE THIS HEATER. Overfiring may
cause a house fire, or can result in permanent dam-
age to the stove and to the catalytic combustor. If any
part of the Defiant other than the baffle and/or catalytic
combustor glows, you are overfiring.
The throat is made of a special cast iron which can
withstand higher temperatures than most other parts
of your stove. It protects the catalytic element from
direct flame impingement, which can shorten the
catalyst’s life. Since the throat is in the direct path of
flame between the firebox and the catalyst, it reaches
higher temperatures than other firebox parts, and it may
glow at times. If it does glow, you will see this directly
through the front doors. The glow is normal and does
not indicate a problem.
At times you may see a glow from the catalyst shining
through the ports of the throat. This is also normal and
does not indicate a problem. The catalytic element,
5. Close the damper when the griddle temperature
reaches 450°F (230°C).
6. Adjust the air control for your desired heat output.
NOTE: Stove installations vary widely, and the operat-
ing guidance given here is only a starting point . The
draft management information on Page 26 will explain
in detail how the features of your installation may help
or hinder good draft, and how you may need to vary
your firing technique if your installation doesn’t encour-
age a good draft.
Refuel While the Embers Are Still Hot
When reloading, best results will be achieved if you first
de-ash the stove by stirring the fuel bed to allow ash to
fall through the grate into the ash pan.
