Gas Burner Air Shutter

NOTE: Air inlet shutters on the burner must be adjust-
ed so sufficient air is metered into the system for prop-
er combustion and maximum efficiency. Before adjust-
ing 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 fol-
lows:

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. Cor-
rect air and gas mixture is indicated if the flame pattern is pri-
marily blue, with small yellow tips, and bends to the right of
the heater section. Too little air is indicated if the flame if yel-
low, lazy and smokey. (A whistling sound from burner could
also be caused by an improper air shutter setting.)

screw.
4. Open or close air shutter as necessary to obtain proper flame
intensity.
