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 the grill, but it can also be done with the burner installed.
Do not flex the drill bit when drilling the ports, as this will cause the drill bit to break. This drill is for burner
ports only, not for the brass orifices (jets) which regulate the flow into the burner. Take care not to enlarge
the holes. Ensure the insect screen is clean, tight, and free of any lint or other debris.
Reinstallation: Reverse the procedure to reinstall the burner. Check that the valve enters the burner when
installing.
WARNING!
When reinstalling the burner after cleaning it is very
important that the valve/orifice enters the burner tube before lighting your
gas grill. If the valve is not inside the burner tube a fire or explosion could
occur.
Troubleshooting
Problem Possible Causes Solution
Low heat / Low flame
when valve turned to
high.
For propane - improper lighting procedure.
For natural gas - undersized supply line.
For both gases - improper preheating.
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.
Pipe must be sized according to
installation code.
Preheat grill with both main burners on
high for 10 to 15 minutes.
Excessive flare-ups/
uneven heat.
Sear plates installed incorrectly.
Improper preheating.
Excessive grease and ash build on sear
plates and in drip pan.
Ensure sear plates are installed with the
holes towards the front and the slots on
the bottom. See assembly instructions.
Preheat grill with both main burners on
high for 10 to 15 minutes.
Clean sear plates and drip pan regularly.
Do not line pan with aluminum foil. Refer
to cleaning instructions.
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 adjustment instructions.
(This must be done by a qualified gas
installer.)
Aluminum Castings
: Clean castings periodically with warm soapy water. Aluminum will not rust, but high
temperatures and weathering can cause oxidation to occur on aluminum surfaces. This appears as white
spots on the castings. To refinish these areas, clean first and sand lightly with fine sandpaper. Wipe the
surface to remove any residue and paint with high temperature barbecue paint. Protect surrounding areas
from over- spray. Follow the manufacture’s directions for curing.
