FLASHBACK
FTRE 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.
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.
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.
IMMEDTATELY
SHUT OFF THE
FLOW
OF GAS AT THE LP TANK
OR NATURAL
GAS VALVE SHOULD
THTS 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.
