Checking and adjusting the burners

The burners are tested and factory-set for most efficient operation. However, variations in gas supply and other conditions may make minor adjustments to air shutter or low flame setting necessary. Adjustments must be done by a qualified service technician.

NOTE: No adjustment can be made to the rotisserie burner (not used on all models) or smoker tray burner(s).

Checking and adjusting the grill burner flames requires removing the grate and sear plates.

Sear burner flame characteristics:

The flames 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 flames will have a slightly yellow tip). A yellow flame indicates not enough air. If flame is noisy or lifts away from the burner, there is too much air. Some yellow tips on flames 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 “Lighting the grill” section.

2.Observe flame to determine which burners need adjustment and how the flame is acting. See “Sear burner flame 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 flame is yellow (not enough air), turn air shutter counter-clockwise.

b.If flame is noisy or lifts away from burner (too much air), turn air shutter clockwise.

Adjustment should be from 1/8" to 1/4".

8.Ignite burner to check flames. See “Sear burner flame characteristics.”

Repeat Steps 1 through 8 above if needed.

Only adjust the burners that need adjustment.

Low flame adjustment:

If flame goes out on the “LO” setting, the low flame setting must be adjusted.

1.Turn off the valve and wait until grill and burners are cool.

2.Remove grill grates, sear plates.

3.Light grill using information in the “Lighting the grill” section.

4.Turn burner to its lowest setting and remove knob.

5.Hold valve stem with pliers and insert a thin flat-blade screwdriver into the shaft.

6.Watch the flame and slowly turn the screwdriver counter-clockwise.

7.Adjust flame to minimum stable flame.
