7. After the burners have been lit for at least 90 seconds, observe the flames through the burner
viewing ports located on each side of the combustion air blower.
The air/gas mixture is properly adjusted when the burner manifold pressure is in accordance with
the applicable table on page 1-6 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 shutter plate with a locking nut. Loosen the
nut enough to allow the shutter to be moved, then adjust the position of the shutter to open or close
the air intake opening until a bright orange-red glow is obtained. Carefully hold the shutter in
position and tighten the locking nut (see illustration on the following page).
