68. MAIN GAS BURNER AIR INLET
SHUTTERS
Air inlet 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 air supply.
Adjust air shutter as follows:
a. Remove the access panel.
b. 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 left of the heater
section. Refer to Figure 25. Too little air is
indicated if the flame is yellow, lazy and
smokey.
c. To adjust the air inlet shutter, loosen adjusting
screw.
d. Slide shutter in or out as necessary to obtain
desired flame intensity.
e. After shutter is adjusted, tighten adjusting
screw securely.
f. If the flame pattern is straight up, insufficient
air is flowing through the tumbler. Refer to
Figure 25. A flame pattern that flares to the
right and left indicates that no air is flowing
through the tumbler.
The air inlet shutters on the burner must be
adjusted so sufficient primary air is
metered into the system for proper
combustion and maximum efficiency.
Before adjusting the inlet shutter be sure
that all lint is removed from lint
compartment and lint screen.
