leak-detection solution. Bubbles will show a leak. Correct any

Check and Adjust the Burners

The burners are tested and factory-set for most effi cient operation.
However, variations in gas supply and other conditions may make
minor adjustments to air shutter or low fl ame setting necessary.
It is recommended that a qualifi ed person make burner
adjustments.
NOTE: No adjustment can be made to the rotisserie burner (not
used on all models).
Checking and adjusting the grill burner fl ames requires removing
the grate and sear plates.
Sear burner fl ame characteristics:
The fl ames of the grill burners and surface burners (not used on
all models) should be blue and stable with no excessive noise or
lifting (L.P./propane gas fl ames will have a slightly yellow tip). A
yellow fl ame indicates not enough air. If fl ame is noisy or lifts
away from the burner, there is too much air. Some yellow tips on
fl ames when the burner is set to HI setting are acceptable as long
as no carbon or soot deposits appear.
Check that burners are not blocked by dirt, debris, insect nests,
etc. and clean as necessary. If they are clean, adjust air shutters
as needed.
IMPORTANT: Before adjusting air shutters, let burners cool down.
Adjusting the air shutters:
1. Light grill using information in the "Grill Use" section.
2. Observe fl ame to determine which burners need adjustment
and how the fl ame is acting. See "Sear burner fl ame
characteristics" above.
3. Turn off the valve and wait until grill and burners are cool.
4. Remove grill grates, sear plates.
5. Remove burner and loosen air shutter adjustment screw.
a. If fl ame is yellow (not enough air), turn air shutter counter-
clockwise.
b. If fl ame is noisy or lifts away from burner (too much air), turn
air shutter clockwise.
Adjustment should be from 1/8" to 1/4".
