This air supply enters at the upper front of the firebox, near the
top of the glass door. This preheated air supplies the neces-
sary fresh oxygen to mix with the unburned gases, helping
to create second, third and fourth combustions. This air is
regulated by the Burn Rate Air Control. There are four settings
High, Medium-High, Medium-Low and Low. When the control
is raised all the way up it is on the High setting and when
pushed all the down it is on the Low setting.
Figure 22.1.
