Record Conversion

The model/serial number plate is located on the right-hand side of the

grill. With a permanent marker, check the box next to “Natural gas” and

mark through “LP.”

In the last page of the Use and Care Guide, write “Conver

ted to Natural

Gas.” Also record the conversion date and the technician/company that

performed the conversion.

NOTE:

Place the LP gas parts in plastic parts bag for future use and

keep with package containing the literature.

Check and Adjust the Burners

The burners are tested and factory-set for most ef

ficient 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: The rotisserie burner cannot be adjusted.

Checking and adjusting the grill burner flames requires removing the

grates and flame tamers.

Burner Flame Characteristics

The flames of the grill burners and side burners (on some models) should

be blue and stable with no excessive noise or lifting (LP 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

completely.

To Adjust:

1. Light grill using information in the “Outdoor Grill Use” section.

2. Observe flame to determine which burners need adjustment and how

the flame is acting.

3. T

urn off the valve and wait until grill and burners cool completely.

4. Remove grill grates and flame tamers.
