8.3.4 Control of the air supply
Once the firewood, firebox and chimney are hot, you can close the air supply for a steady
burn.
If the flames get very small and almost disappear when you close the air, you have closed
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 closed.
When the furnace is using a thermostat, it is the thermostat that controls the air inlet
damper. When the thermostat calls for heat, the damper opens and the combustion is
stirred up. When the furnace gets hot enough, the blower motor is activated.
The following figure shows the position of the air inlet damper (A) according to the position
of the air inlet damper switch (B).
