TROUBLESHOOTING
MAINTENANCE INSTRUCTIONS
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.

BURNER - The burner is made from heavy wall 304 stainless steel, but due to the extreme
heat and corrosive 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
located in the center of either burner. Lift the back of the 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 temperatures
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
BURNER PORT
Turn off the gas at the source and disconnect unit before servicing. Maintenance should only be done when the grill is cool, to
avoid the possibility of burns. Aleak test must be performed annually,and whenever any component of the gastrain is replaced.
COMBUSTIONAIRADJUSTMENT - (This mustbe done by a qualified gas installer.) The air shutter is factory setand should not 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.
