WARNING
To reduce the risk of electric shock, fire,
explosion, serious injury or death:
• Disconnect electric power to the tumble
dryer before servicing.
• Close gas shut-off valve to gas tumble
dryer before servicing.
• Close steam valve to steam tumble
dryer before servicing.
• Never start the tumble dryer with any
guards/panels removed.
• Whenever ground wires are removed
during servicing, these ground wires
must be reconnected to ensure that the

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:
Refer to Figure 38.
1. Remove the upper access panel and 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.
