WARNING!
Always wear protective gloves and safety glasses when cleaning your grill.
WARNING!
Turn off the gas at the source and disconnect the unit before servicing. To avoid 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.
Maintenance Instructions
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.
2. Loosen air-shutter lock screw located at the mouth of the burner and open or close air shutter as re
-
quired. The normal opening settings are:
Main Tube Burner
Propane 5/32” (4mm)
Natural 5/32” (4mm)
*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.
Tube Burner: The burners are 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!
Beware of Spiders.
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 yel
-
low or orange flame or cause a fire (flashback) at the air shutter beneath the control panel. To clean the
inside of the burner, it must be removed from the gas grill: Remove the screw that attaches the burner to
the back wall. Slide the burner back and upwards 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
burner ports and valve orifices for blockages. Burner ports can close over time due to cooking debris and
corrosion, use an opened paperclip or the supplied port maintenance bit to clean them. Drill out blocked
ports using this drill bit in a small cordless drill. The ports are easier to clean if the burner is removed from

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.
