Adjust High Flame Setting Screw
When converting from LP Gas to Natural Gas, you will need to
adjust the high flame setting screw for ideal burner flame
height.
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 the 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 HIGH setting are acceptable
as long as no carbon or soot deposits appear. The flames
should be approximately 2.5 cm high.
1. Remove each control knob for the main burners.
2. Use a flat-blade screwdriver to turn the high flame
setscrew counterclockwise approximate 90º.
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.
4. Place the burner control knobs back to their original
positions.
5. Repeat step 2 through 4 for each burner if need.
6. Replace te flame tamers and grates after the burners have
been cooled down.
Record Conversion
The LP appliance nameplate is located inside the grill cabinet
on the left-hand side. Once converted, place the NG appliance
nameplate as close as possible to the current LP appliance
nameplate without covering it.
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.
