Gas Burner Air Shutter
NOTE: 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 compartments 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 and remove the burner inspection
hole plate.
2. Start the tumble dryer and check the flame pattern. If the
flame pattern is straight up, insufficient air is flowing
through the tumble dryer. A flame pattern that flares to the
right and left indicates no air is flowing through the tumble
dryer. 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 if yellow, lazy and smokey.
3. To adjust the air shutter, loosen air inlet shutter adjusting
screw.
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.

the exhaust duct. These should be checked and the required
corrective action taken.
