4.4.4  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 FIREPLACE UNATTENDED WHILE A NEW LOAD IS BEING 
FIRED HOT. 
DO NOT OVERFIRE. 
When you burn a new load of wood hot to heat up the wood, the fireplace and the 
chimney, the result will be a surge of heat from the fireplace. 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. 
4.4.5  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 fireplace 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 fireplace 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 
correct air control use, the flames should slow down, but should stay large and steady, 
even as the air supply is reduced.
