Adjusting For Proper Flame - ProFire 48G Owner's Manual & Installation Instructions

ADJUSTING FOR PROPER FLAME AND EFFICIENCY
Each burner is tested and adjusted at the factory prior to shipment. However, variations in the local
gas supply or conversion from one gas to another may make it necessary to adjust the burners. The
flames of the grill burners should be visually checked. The rear broiler (when equipped) should have
a very low flame (no more than 1/4") and glow with a light red color. There is no air shutter adjust-
ment for the rear broiler. On the main burners and side burners the flames should be blue and stable
with small yellow tips and no excessive noise or lifting. If the burners do not operate correctly, check
if the air shutter or burner ports are blocked by dirt, debris, spider webs, etc. and proceed with air
shutter adjustment. The amount of air which is drawn into a burner is governed by a metal cup at the
inlet of the burner called an air shutter. It is locked in place by a screw, which must be loosened prior
to lighting the burner for adjustment. To access the grill burner air shutters, first, remove the valve
panel by removing the screws on the corners of the valve panel. Remove the control knobs. Pull the
valve panel outwards while unplugging the rotary ignitors. With a screwdriver, loosen the screw on
the side of the air shutter. Light the burner and adjust according to the directions below. Access and
adjustment of the side burner air shutters is done in the same manner as the main burners.
A yellow flame indicates insufficient air: Open the air shutter to allow more air to the burner.
Flame is noisy, blows out, or lifts away from burner or will not light, this indicates too much air:
Close the air shutter. Once the air shutter is adjusted turn the burner off and reverse steps to
reassemble.
