AIR SETTINGS
The high output (when there is a heat demand) is set in the factory and can not be adjusted. The low output (standby)
can be adjusted with the screw on the primary air blade (see fig 25) situated behind the draft box underneath the loading
door. It controls the gap A. The bigger the gap, the more combustion air enters into the firebox, the higher the low burn.
Every installation is different because of draft, kind of wood being used and geographic location.
Adjust the flap in a way that it maintains a fire overnight on standby but not using high amounts of wood.
THERMOSTATS
If your furnace is operating as a combination unit remember both units will not fire at the same time. If the wood furnace
is to be your main source of heat, set the wood thermostat at your desired room temperature and set the thermostat from
your alternate furnace approximately 5
°
F (3
°
C) lower.
Note:
If the alternative furnace is running and the wood furnace is starting to heat up after (re-)loading, the alternate
furnace will shut off automatically.
When programmable thermostats are used, it is recommended that the wood thermostat is programmed so the Apex will
fire up before the alternate furnace will. This will give the Apex time to build up a hot fire again after being in standby
mode.
