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:
