MAIN GAS BURNER AIR SHUTTER
All Gas Models
NOTICE: Air inlet shutters on the burner must be
adjusted so sufficient air is metered into the system
for proper combustion and maximum efficiency.
Before adjusting the inlet shutters be sure that all lint
is removed from lint compartment and lint screen.
Air shutter adjustments will vary from location to
location and will depend on the vent system, number of
units installed, make-up air and line gas pressure.
Opening the shutter increases the amount of primary air
supplied to the burner while closing the shutter decreases
the primary air supply. Adjust air shutter as follows:
1. Open the access panel.
2. Start the tumbler and check the flame pattern. Correct
air and gas mixture is indicated if the flame pattern is
primarily blue, with small yellow tips, and bends to
the right of the heater section. Too little air is
indicated if the flame is yellow, lazy and smokey.
Refer to Figure 16.
3. To adjust the air shutter, loosen air inlet shutter
adjusting screw. Refer to Figure 16.
4. Open or close air shutter as necessary to obtain
proper flame intensity.
5. After air shutter is adjusted for proper flame, tighten
air shutter adjusting screw securely. Control panel
may have to be removed temporarily to loosen air
shutter screws to adjust shutter.
6. If the shutter is correctly adjusted, but the flame
pattern is straight up, insufficient primary air is
flowing through the tumbler and airflow switch is
improperly set. A flame pattern that flares to the right
and left indicates no air is flowing through the
tumbler. Refer to Figure 16.
