Air Control
The Start-Up Air Control function is to activate the
Automatic Combustion Control system (ACC). This
function is performed by pushing the control all the way
back until it stops and then pulling forward to the front
of the appliance until it stops. This activates the ACC
system and opens the front air channel and allows air
to enter the front of the appliance for approximately
25 minutes. The front air channel gradually shuts
down until it is completely closed at the end of the 25
minutes. The fire is now controlled by the air supplied
by the Burn Rate Air Control. This function should be
performed each time you reload the appliance. Start up
