remove
the
burner
assembly.
a.
Remove
the
five
wide
pan

holding
the
burner
to
the
combustion

There
are
three
at
the
top
of
the

There
are
two
at
the
bottom
of
the

be
hard
to
take
out,
so
try
the
following:
i.
With
pliers,
grasp
between
the
oval
air
vents
in
the
front
of
the
burner
on
the
far
left
and
pull
firmly.
Repeat
on
the
right
vent.
ii.
Now
pull
from
the
center
and
it
should
slide
out
readily.
d.
Inspect
the
gasket.
(Minor
surface
tears
are
allowable.
Major
separations
are
not
acceptable.
7)
CLEAN
THE
BURNER
–
Use
degreaser
in
a
pump
action
bottle.
a.
Protect
the
burner
gasket
from
direct
water
pressure
.
IF
the
gasket
becomes
compromised,
please
contact
the
Technical
Service
Department
for
further
assistance.
b.
Thoroughly
saturate
the
burner
with
the
cleaning
solution
from
the
top,
down
through
the
slots,
as
well
as
the
openings
in
the
front
of
the
burner
until
the
burner
is
soaking
wet.
c.
Let
the
burner
sit
for
5
minutes.
d.
Remove
the
burner
from
the
solution.
Set
the
burner
in
a
sink
in
its
normal
upright
position
and
wash
the
burner
with
a
high
flow
of
water
down
into
the
slots,
starting
at
the
back
and
moving
forward.
Again,
ensure
that
no
contact
is
made
with
the
gaskets.
e.
Use
compressed
air
to
clear
excessive
water
from
the
burner
after
rinsing.
Inspect
the
gasket.
(Minor
surface
tears
are
allowable.
Major
separations
are
not
acceptable)
8)
FAN
‐
The
fan
is
probably
coated
with
dust
as
well.
a.
Place
a
towel
at
the
bottom
of
the
heat
exchanger
to
cover
the
square
port
to
the
fan.
This
towel
will
catch
all
the
dust
blown
in
the
next
step.
b.
Use
compressed
air
to
blow
into
the
fan.
It
will
rotate
and
dust
will
fly
out
of
the
fan
housing
into
the
towel
above.
