5.3.3 Raking Charcoal
When the room temperature is cooler, it is time to reload the insert. Remove the ashes first, then
rake charcoal towards the front of the firebox before reloading. Most of the remaining charcoal will
be at the back of the firebox, furthest from the door. Rake the coals towards the door before loading.
Raking the coals is useful for two reasons. First, it brings them near where most of the combustion
air enters the firebox. This will ignite the new load quickly. Secondly, the charcoal will not be
smothered by the new load of wood. When the embers are simply spread inside the combustion
chamber, the new load smoulder for a long time before igniting.
5.3.4 Firing Each New Load Hot
Place the new load of wood on and behind the charcoal. Close the door and open the air control
fully 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 the following things:
•
Removes surface moisture from the wood,
• Creates a layer of char on the wood, which slows down the smoke release,
• 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 INSERT 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 insert and the chimney, the result
will be a surge of heat from the insert. 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.
5.3.5 Controlling the Air Intake
Once the firewood, firebox and chimney are hot, you can begin to reduce the air supply for a steady
burn.
As the air intake is reduced, the burn rate decreases. This has the effect of distributing the thermal
energy of the fuel over a longer period of time. In addition, the flow rate of exhaust through the insert
and flue pipe slows down, which increases the duration of the energy transfer of the exhaust gases.
As the air intake is reduced, the flame slows down.
