CLEANING THE BURNER jub ES AND BURNER PORTS
To reduce the chance of FLASHBACK FIRE you must
clean the burner tubes as follows periodically in
summer and fall, wherever spiders are active in your
area, and if your grill has not been used for an
extended period of time.
1. Turn all burner control knobs to the "OFF"
position.
2. Turn the LP gas tank valve to the "OFF" position.
3. Disconnect the LP gas regulator assembly from
the LP gas tank.
4. Remove the cooking grates, heat tents, and
warming rack from the grill.
5. Remove the screw from the rear of each burner
using a Phillips head screwdriver.
6. Carefully lift each burner up and away from the
gas valve orifice.
7. Check and clean burner tubes for insects and
insect nests. A clogged tube can lead to a fire
beneath the grill.
8. Refer to FIGUREl and use one of these three
cleaning methods:
METHOD 1: Bend a stiff wire or wire coat
hanger into a small hook as shown and run the
hook through the burner tube and Inside the
burner several times to remove debris.
METHOD 2: Use a bottle brush with a flexible
handle and run the brush through the burner
tube and inside the burner several times to
remove any debris.
METHOD 3: Use an air hose to force air
through each burner tube. The forced air
should pass debris or obstructions through the
burner and out the ports. Always wear eye
protection If using this method.

Burner Ports
Í
Small insects, such as spiders, are able to access the
burner tubes. Sometimes they will build nests or
spin webs. In either case, this can block or reduce
the amount of gas flowing through the burner. You
will usually see a smaller flame, or a flame that Is
mostly yellow rather than blue, coming from the
burner when this happens. Other signs include the
gill not heating evenly, not reaching temperature, or
burners not igniting. In cases with severe blockage,
this can cause the flame to burn backwards, and
outside of the burner tubes, which can cause
damage to your grill and/or personal Injury.
IMMEDIATELY SHUT OFF THE FLOW OF GAS AT
THE LP TANK OR NATURAL GAS VALVE SHOULD
THIS HAPPEN.
Wait for the grill to cool, and then
clean all burners.
Regardless of the burner cleaning procedure you use,
we recommend you also complete the following steps
to help prolong burner life.
1. Use a fiber pad or nylon brush to clean the entire
outer surface of each burner until free of food
residue and dirt.
2. Clean any clogged ports with a stiff wire, such as
an open paper clip.
3. Inspect each burner for damage (cracks or holes)
and if such damage is found, order and install a
new burner. After Installation, check to ensure that
the gas valve orifices are correctly placed Inside
the ends of the burner tubes. Also check the
position of your electrodes.
4. Never enlarge the burner ports during cleaning.
For safe operation ensure the gas valve assembly
orifice is inside the burner tube before using your
grill. See figure. If the orifice Is not Inside the
burner tube, lighting the burner may cause
explosion and /or fire resulting in serious bodily
injury and /or property damage.

BURNER FLAMES
Always inspect the burner flame after lighting. A
good flame should be primarily blue with a yellow
tip and have a minimum amount of noise. Some
yellow tips are OK if under one inch. New burners
sometimes have oil residue, which will cause yellow
flame when burning off. Variations in gas supply,
altitude, weather, and other factors can all Impact
burner performance. Older grills can also show
more yellow flame as food deposits, oils, and fats
can build up.
