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.
