Adjusting For Proper Flame - ProFire PERF30R Owner's Manual

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 adjustment 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. (Main burners only) It is
locked in place by a screw, which must be loosened prior to lighting the burner for ad-
justment. To access the grill burner air shutters, remove the burner by removing the
screw that holds the burner in place and push the burner forward and up. With a screw-
driver, loosen the screw on the side of the air shutter. Adjust the air shutter (open or
close) according to the directions below.
BURNER AIR ADJUSTMENT
BE CAREFUL AS THE BURNER MAY BE VERY HOT!
An all yellow flame indicates insufficient air: Open the air shutter to allow more air to
the burner. Yellow tips on the flame are normal. 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.
Loosen screw on air shutter. Adjust air shutter. Install burner.
Tighten after adjusting. Tighten screw.
