We recommend this gas grill be thoroughly inspected and serviced annually by a qualified service person.
EN
At all times keep the gas grill area free from combustible materials, gasoline and other flammable vapors
and liquids. Do not obstruct the flow of ventilation and combustion air. Keep the cylinder enclosure
ventilation openings (located on the cart sides and at the front and back of the bottom shelf) free and
clear from debris.
WARNING!
!
WARNING!
the possibility of burns, maintenance should be done only when the grill is cool. A leak test must be
performed annually and whenever any component of the gas train is replaced or gas smell is present.
Combustion Air Adjustment: (This must be done by a qualified gas installer.) The air shutter is factory set
and should not need adjusting under normal conditions. Under extreme field conditions, adjustments
might be required. When the air shutter is adjusted correctly the flames will be dark blue, tipped with
light blue and occasionally yellow.
• With too little air flow to the burner, the flames are lazy yellow and can produce soot.
• With too much air flow, the flames lift erratically and can cause difficulties when lighting.
Adjusting the air shutter:
1. Remove cooking grids and sear plates and leave lid open. You may have to open the door or remove
the top drawer (if equipped) to access the air-shutter screw located at the mouth of the burner. The back
cover must be removed for rear tube burner air shutter adjustment.
2. Loosen air-shutter lock screw and open or close air shutter as required. The normal opening settings
are:
Main Tube Burner Propane 1/2" (13mm)
Smoker Burner
*Infra-Red burners have no air adjustment.
3. Light the burners and set to high. Visually inspect burner flames. When the shutters are set correctly,
turn burners off, tighten locking screws, and replace removed parts. Ensure that the insect screens are
installed.
