CAUTION: BEWARE OF FLASHBACK
CAUTION: Spiders and smail insects occa­
sionally spin webs or make nests in the grill
Burner Tubes during transit and warehousing.
These webs can lead to a gas flow obstruc­
tion which could result in a fire in and
around the Burner Tubes. This type of fire is
known as a "FLASHBACK" and can cause
serious damage to your grill and create an
unsafe operating condition for the user.
To reduce the chance of "FLASHBACK", you
must clean the burner tubes before assem­
bling your grill, and at least once a month in
late summer or early fall when spiders are
most active. Also perform this Burner Tube
cleaning procedure if your grill has not been
used for an extended period of time.
Flashback Prevention
To reduce the chance of "FLASHBACK" (see
CAUTION at right) dean the Burner Tubes and
Burners before fully assembling your grill. Re­
move the Cotter Pin from the rear underside of
each Burner using a pair of long nose pliers.
Carefully lift each Burner up and away from the
Gas Valve Orifice, then refer to Figure 1 and
perform one of these three cleaning methods:
1
. Bend a stiff wire, (a lightweight coat hanger
works well) into a small hook as shown
below. Run the hook through the Burner
Tube and inside the Burner several times to
remove any debris.
C
2
.
3.
Use a bottle brush with a flexible handle.
Run the brush through the Burner Tube and
inside the Burner several times, removing any
debris.
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.

A warning
The location of the Burner Tube with respect
to the Orifice is vital for safe operation.
Check to ensure the Orifice is inside the
Burner Tube before using your gas grill. See
Figure 2. If the Orifice is not inside the
Burner Tube, lighting the Burner may cause
explosion and/or fire.
