Tube Burner: The burners are made from heavy wall 304 stainless steel, but extreme heat and a corrosive
environment can cause surface corrosion to occur. This can be removed with a brass wire brush.
CAUTION!
EN
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 reduces the likelihood of insects building nests inside the burner
but does not entirely eliminate the problem. A nest or web can cause the burner to burn with a soft yellow
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!
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.
Infrared Burners: Because of the high intensity of the infrared burner, most drippings and food particles
that fall onto the burner surface are immediately incinerated. However, some debris and residue may
remain. To remove this residue after cooking, operate the grill on high for 5-10 minutes. Do not clean the
ceramic tile with a wire brush.
Protection Of Infrared Burners: The infrared burners of your grill are designed to provide a long service
life, though care must taken to prevent cracking of their ceramic surfaces. Fractures will cause the burners
to malfunction. The following provides a few of the causes of cracks and the steps you can 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.
2. Contact with water or other liquids - Cold liquids contacting the hot ceramic surfaces can cause them
to break. Never throw water into the grill to douse a flame. If the ceramic or interior of a burner becomes
wet while not in use, later operation of the burner can create steam, which can produce sufficient
pressure to crack the ceramic. Repeated soaking of the ceramic can also cause it to swell and expand. This
expansion causes undue pressure on the ceramic that can cause it to crack and crumble.
the ceramic for evidence of possible watersoaking. If the ceramic appears to be wet, remove the burner
from the grill. Turn it upside down to drain the excess water and bring indoors to dry thoroughly.
3. Impaired ventilation of hot air from the grill - 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 can become deprived of oxygen
causing them to back-flash. If this occurs repeatedly, the ceramic could crack. Never cover more than 75%
of the cooking surface with solid metal (i.e., griddle or large pan).
4. Incorrect cleaning - Do not clean the ceramic tile with a wire brush. If debris is collecting on your
burner, light the burner and operate on high for 5 minutes with the lid open, allowing debris to burn off.

Beware of Spiders.
When reinstalling the burner after cleaning it is very important
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
