4.3.4 Firing Each New Load Hot

Place the new load of wood on and behind the charcoal, and not too close to the glass.
Close the door and open the air control fully. Leave the air control fully open until the
firebox is full of flames, the wood has charred to black and its edges are glowing red.
Firing each load of wood hot accomplishes a few things:
• drives the surface moisture from the wood,
creates a layer of char on the wood, which slows down its release of smoke,
•
• heats the firebox components so they reflect heat back to the fire, and
heats the chimney so it can produce strong, steady draft for the rest of the cycle.
•
Although it is important to fire each new load hot to prepare for a clean burn, do not allow
the fire to burn at full intensity for more than a few minutes.
DO NOT LEAVE THE STOVE UNATTENDED WHILE A NEW LOAD IS BEING FIRED
HOT.
When you burn a new load of wood hot to heat up the wood, the stove and the chimney,
the result will be a surge of heat from the stove. This heat surge is welcome when the
room temperature is a little lower than desirable, but not welcome if the space is already
warm. Therefore, allow each load of wood to burn down so that the space begins to cool
off a little before loading. Letting the space cool before loading is one of the secrets to
clean burning and effective zone heating.
Never overfire your stove. Overfiring can lead to overheating of combustible materials
nearby, damage to the stove, and in extreme cases, cause a fire.
Overfiring is caused by too much air flowing through the stove too quickly, bad gaskets or
bad operation of the air control.
Overfiring can be seen by excessive fuel consumption, and may cause parts of the stove
or chimney connector to glow red. If you notice signs of overfiring, reduce the air supply to
the fire, and make sure all gaskets are in good conditions.

4.3.5 Turning Down the Air Supply

Once the firewood, firebox and chimney are hot, you can begin to reduce the air supply for
a steady burn.
As you reduce the air supply to the fire, two important things happen. First, the firing rate
slows down to spread the heat energy in the fuel over a longer period of time. Second, the
flow rate of exhaust through the stove and flue pipe slows down, which gives more time for
the transfer of heat from the exhaust. You will notice that as you reduce the air setting, the
flames slow down. This is your indication that the stove is burning at its peak efficiency.
If the flames get small and almost disappear when you turn down the air, you have turned
down the air too early, or your firewood is wetter than it should be. With good fuel and
