BURNER - The burner is made from heavy wall 304 stainless steel, but due to the extreme heat and corro-
sive environment, surface corrosion will occur. Use a brass wire brush to remove surface corrosion. Clean
any blocked ports using an opened paper clip. Do not enlarge the burner ports. 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 will reduce the likelihood of insects building nests inside the burner, but does not
entirely eliminate the problem. The nest or web will 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)
located either in the center of the burner on 308 models, or above the burner to the left and right
of the centre of the burner on 450 models. Lift back of burner upwards to remove. Use a flexible
venturi tube cleaning brush to clean out the inside of the burner. Shake any loose debris out of
the burner, through the gas inlet. Ensure that the insect screen is clean, tight, and free of any lint
or other debris. Check also that the valve orifices are clean. Do not enlarge the orifices. Re-install the
burner. Check that the valve enters the burner when installing. Replace burner cover and mounting screws to complete
installation.
ALUMINUM CASTINGS - Clean castings periodically with warm soapy water. Aluminum will not rust, but due to high tempera-
tures and weathering, oxidation can occur on aluminum surfaces. This will appear as white spots on the castings. To refinish
the castings, clean them and sand lightly with fine sandpaper. Wipe surface to remove any residue, and paint with high
temperature barbecue paint. Protect surrounding areas from over-spray. Follow curing directions found on the can.

BURNER PORT
Turn offthe gas at the source and disconnectunit before servicing. Maintenance should only be donewhen the grill is cool,to
avoid the possibilityof burns. Aleak testmust beperformed annually, andwhenever anycomponent ofthe gastrain is replaced.
COMBUSTIONAIRADJUSTMENT -(This mustbe doneby aqualified gas installer.) The airshutter isfactory setand shouldnot have
to be adjusted under normal conditions. However, some extreme field conditions may exist that require adjustment. When the air
shutter is adjusted correctly, the flames will be dark blue with light blue tips, and occasional yellow tips.
YELLOW TIPPING
If the burner is getting too little air, the flames will be lazy yellow, and possibly produce soot. If the burner is getting too much air, the
flames will be lifting erratically from the burner and may cause difficulties when lighting.
HOSE - Check for abrasion, melting, cuts and cracks. If any of these conditions exist, do not use gas grill. Have part replaced by your
gas grill dealer, or qualified gas installer.

Problem Possible Causes Solution
Low heat / Low flame when
valve turned to high.
For propane - improper lighting
procedure.
Ensure lighting procedure is followed carefully. All gas grill
valves must be in the off position when the tank valve is turned
on. Turn tank on slowly to allow pressure to equalize. See
lighting instructions.
For natural gas - undersized sup-
ply line.
Pipe must be sized according to installation code.
For both gases - improper pre-
heating.
Pre-heat grill with both main burners on high for 10 to 15
minutes.
