Checkingand
adjustingthe
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 infrared 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 burnerflame 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.Rtpropane
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.

"Lighting the grill" section.
