The air/gas mixture is properly adjusted when the burner manifold pressure is in accordance with the applicable
table on page 2-7 and the burners display a bright orange-red glow. If a blue flame is observed, or if there are dark
spots on a burner face, the air/gas mixture requires adjustment.
On the side of the blower housing opposite the motor is a plate with one or two locking nuts (see illustration on the
following page). Loosen the nut(s) enough to allow the plate to be moved, then adjust the position of the plate to
open or close the air intake opening until a bright orange-red glow is obtained. Carefully hold the plate in position
and tighten the locking nut(s).
