Maintenance Instructions
WARNING! Keep the grill away from combustible materials, gasoline, and other flammable vapors and liquids.
!
COMBUSTION IN AIR ADJUSTMENT
!
IMPORTANT! This must be done by a qualified gas installer.
• The air shutter is factory set and should not require adjusting under
normal conditions. Adjustments might be required under extreme field
conditions.
• The flames of the air shutter will be dark blue, tipped with light blue and
occasionally yellow when adjusted correctly.
• Too little air flow to the burner will produce soot and lazy yellow flames.
• Too much air flow to the burner will cause flames to lift erratically and
cause igniting difficulties.
Adjusting the Air Shutter
1. Remove cooking grids and sear plates. Leave lid open.
2. You may have to open the cabinet door or remove the top drawer (if
equipped) to access the air shutter screw located at the mouth of the
burner.
3. Remove the back cover to adjust rear tube burner air shutter.
4. Loosen air shutter lock
screw and open or close air
shutter as required.
(Fig. 1)
5. Light the burners on high.
6. Visually inspect burner
flames.
7. Turn burners off, tighten
locking screws, and replace
removed parts when
shutters are set correctly.
8. Ensure insect screens are
installed.
Note: Infrared burners have no
air adjustment.
