Start-up Air System
The combustion air enters at the rear of the firebox through
the rear air tubes. This air supply is controlled by the Start-
up Air Control.
Primary Air System
The primary air enters at the upper front of the firebox, near
the top of the glass door. This preheated air supplies the
necessary fresh oxygen to mix with the unburned gases,
helping to create second, third and fourth combustions.
This air is regulated by the Primary Air Control. For more
primary air push control "IN", for less air pull control "OUT".
