Maintenance Instructions

We recommend this gas grill be thoroughly inspected and serviced annually by a qualified service person.
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!
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.

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.
Burner: The burner is made from heavy wall 304 stainless steel, but extreme heat and a corrosive
environment can cause surface corrosion to occur. This can be removed with a brass wire brush.
CAUTION!
Spiders and insects are attracted to the smell of propane and natural gas. The burner is equipped with an
insect screen on the air shutter, which reduces the likelihood of insects building nests inside the burner
but does not entirely eliminate the problem. A nest or web can cause the burner to burn with a soft yellow
or orange flame or cause a fire (flashback) at the air shutter underneath the control panel. To clean the
inside of the burner, it must be removed from the gas grill: Remove the screw (s) that attaches the burner
to the back wall. Slide the burner back and up wards to remove. Cleaning: Use a flexible venturi tube brush
to clean the inside of the burner. Shake any loose debris from the burner through the gas inlet. Check the
