Check and Adjust the Burners

3.Test all connections by brushing on an approved noncorrosive leak-detection solution. Bubbles will show a leak. Correct any leak found.

4.Go to “Check and Adjust the Burners” section.

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.

It is recommended that a qualiﬁed 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 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 “Grill Use” 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”.

6. Tighten air shutter adjustment screw.

7.Replace burner sear plates and grates.

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

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 “Grill Use” 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.

9.Repeat Steps 3 through 8 for each burner if needed.

10.Replace the sear plates and grates after the burners have cooled.
