valve is open when the handle is parallel to the gas pipe.

detection solution. Bubbles will show a leak. Correct any leak
found.
Record Conversion
1. The appliance nameplate is located inside the grill cabinet on
the left-hand cabinet side. With a permanent marker, check
the box next to “Natural gas” and mark through “LP -
Propane.”
In the last page of the Use and Care Guide, write “Converted to
Natural Gas.” Also record the conversion date and the
technician/company that performed the conversion.
NOTE: Place LP gas parts in plastic parts bag for future use and
keep with pack containing literature.
Adjust High Flame Setting Screw
When converting from LP to Natural gas, you will need to adjust
the high flame setting screw for ideal burner flame height.
1. Remove each control knob for the main burners and side
burner by loosening the set screw with the Allen key.
2. Use a flat-blade screwdriver to turn the high flame setscrew
counterclockwise approximate 90°.
3. Check that burner operates at the new high flame setting. It
may be necessary to adjust the screw setting slightly more to
get the ideal burner flame height.
Check and Adjust 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.
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. The flames should be approximately 1" (2.5 cm)
high.
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.
