SET GAS PRESSURE:
Gas pressure regulator is factory set.
SET PILOT FLAME:
Remove all burner control knobs, then remove the front panel.
The pilot adjustments are near the control valve for each set of
burners.
Using a small, flat-blade screwdriver, turn the screw clockwise to
decrease the flame size, or counter-clockwise to increase the
flame
size.
Adjust the pilot flame to 1/4” high. Test for operation: all sections
of the burner must light without undue delay. Drafty conditions
may require a higher flame to allow the pilot to remain lit.
Replace the front panel and all knobs before returning the unit to
service.
ADJUST BURNER FLAME:
Remove all burner control knobs, then remove the front panel.
Turn an individual burner on.
Loosen the locking screw on the shutter.
Turn the shutter to admit more or less air as required. Adjust the
air shutter until the flame is mostly blue in color.
Tighten the locking screw when finished. Replace the front panel
and all knobs before returning the unit to service.
