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.
TROUBLESHOOTING
Problem Possible Causes Solution
Low heat / Low flame when
valve turned to high. For propane - improper light-
ing 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
supply line. Pipe must be sized according to installtion code.
For both gases - improper pre-
heating. Pre-heat grill with both main burners on high for
10 to 15 minutes.
Excessive flare-ups/un-
even heat. Sear plates installed incorrectly. Ensure sear plates are installed with the holes
towards the front, and the slots on the bottom.
The group of five holes must be in the centre of
the grill. See assembly instructions.
Improper pre-heating. Pre-heat grill with both main burners on high for
10 to 15 minutes.
Excessive grease and ash build
up on sear plates and in drip
pan. Clean sear plates and drip pan regularly. Do
not line pan with aluminum foil. Refer to clean-
ing instructions.
Screw
Burners burn with yellow
flame, accompanied by the
smell of gas. Possible spider web or other
debris, or improper air shutter
adjustment. Thoroughly clean burner by removing. See
general maintenance instructions. Open air
shutter slightly according to combustion air ad-
justment instructions.
