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 2 screws located above the

burner to the left and right of the centre of the burner. 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.

MAINTENANCE INSTRUCTIONS

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. A leak test must be performed annually, and whenever any component of the gas

train is replaced.

COMBUSTION AIR ADJUSTMENT - (This must be done by a qualified gas installer.) The air shutter is factory set and 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.

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.

1. To adjust the air shutter, remove cooking grids and sear plates and leave lid open. The back cover must be removed for back

burner air shutter adjustment.

2. Loosen air-shutter lock screw and open or close air shutter as required. The normal settings are:

Main Burner Propane 3/16" Back Burner Propane 3/8"

Natural 1/8" Natural 1/8"

3. Light burners and set to high. Visually inspect burner flames. When shutters are set, turn burners off, tighten locking screw,

and replace removed parts.

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.
