Cleaning
the
Burner
Assembly
Follow
these
instructions
to
clean
and
/
or
replace
parts
of
burner
assembly
or
if
you
have
trouble
igniting
grill.
1.
Turn
gas
off
at
control
knobs
and
LP
Tank.
2.
Remove
cooking
grates,
grease
tray
and
grease
cup.
3.
Remove
screw
at
end
of
burner
using
a
screwdriver.
4.
Carefully
lift
each
burner
up
and
away
from
valve
openings.
Inspect
burner
for
any
damage
(cracks
or
holes).
If
damage
is
found,
replace
with
a
new
burner.
Reinstall
the
burner,
check
to
ensure
that
the
Gas
valve
orifices
are
correctly
positioned
and
secured
inside
the
burner
inlet.
We
suggest
three
ways
to
clean
the
burner
tubes.
Use
the
one
easiest
for
you.
(A)
Bend
a
stiff
wire
(a
light
weight
coat
hanger
works
well)
into
a
small
hook.
Run
the
hook
through
each
burner
tube
and
burner
several
times.
(B)
Use
a
narrow
bottle
brush
with
a
flexible
handle
(DO
NOT
use
a
brass
wire
brush),
run
the
brush
through
each
burner
tube
and
burner
several
times.
(C)
Wear
eye
protection:
use
an
air
hose
to
force
air
into
the
burner
tube
and
out
the
air
ports.
Check
each
port
to
make
sure
air
comes
out
each
hole.
5. Wire brush entire outer surface of burner to remove food residue and dirt.
INSECTS.
FACT:
sometimes
spiders
and
other
insects
climb
into
the
grill
tubes
attached
to
the
burners.
The
spiders
spin
webs,
build
nests
and
lay
eggs.
The
webs
or
nests
can
be
very
small,
but
they
are
very
strong
and
can
block
the
flow
of
gas.
Clean
burners
prior
to
use
after
storing,
at
the
beginning
of
the
grilling
season
or
after
a
period
of
one
month
of
the
unit
not
being
used.
Spider
guards
are
on
the
air
intakes
in
an
effort
to
reduce
this
problem,
but
it
will
not
eliminate
it!
An
obstruction
can
result
in
a
“flashback”
(a
fire
in
the
burner
tubes).
The
grill
may
still
light,
but
the
obstruction
does
not
allow
full
gas
flow
to
the
burners.
