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 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.
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.
TROUBLESHOOTING
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
supply line.
Pipe must be sized according to installation code.
For both gases - improper
preheating.
Pre-heat grill with both main burners on high for 10 to 15
minutes.
PROTECTION OF INFRARED BURNERS - The infrared burners of your grill are designed to provide a long service life. However,
there are steps you must take to prevent cracking of their ceramic surfaces, which will cause the burners to malfunction.
Following are the common causes of cracks and the steps you must take to avoid them. Damage caused by failure to follow
these steps is not covered by your grill warranty.
1. Impact with Hard Objects - Never allow hard objects to strike the ceramic. Take care when inserting or removing cooking
grates and accessories into or from the grill. If these objects were to fall on the ceramic, it is likely to crack.
2. Water or Other Liquids - Cold liquid contacting a hot surface in substantial amounts can cause the surface to break. Do
not throw water into the grill to douse a flame. Also if the ceramic or interior of a burner becomes wet while not in use, later
operation of the burner can create steam, which may produce enough pressure to crack the ceramic. In addition, repeated
soaking of the ceramic will cause it to swell and expand. This expansion will cause undue pressure on the ceramic and
therefore it may crack and crumble.
i) Never throw water into the grill to control flare-ups
ii) Do not attempt to operate the infrared burners in open air while raining.
iii) If you find standing water in your grill (because of exposure to rainfall, sprinklers etc.), inspect ceramic for
evidence of possible watersoaking. If ceramic appears to be wet, remove the burner from the grill. Turn upside
down to drain the excess water. Bring indoors and allow to dry thoroughly.
3. Impaired Ventilation of Hot Air From the Grill - In order for the burners to function properly, hot air must have a way to escape
the grill. If the hot air is not allowed to escape, the burners may become deprived of oxygen, causing them to back flash. If this
occurs repeatedly, the ceramic may crack. Do not cover more than 75% of the cooking surface with solid metal (ie. griddle or
large pan).
Excessive flare-ups/uneven
heat.
Sear plates installed incorrectly. Ensure sear plates are installed with the holes towards
the front, and the slots on the bottom. 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 cleaning instructions.
