free from
combustible
materials, gasoline
and
other flammable vapors
and
liquids.
Retrieving
Objects from Inside
the
Heater
Should
an
object fall inside
the
heater, through
the
grill
openings,
it
must
be
removed
to
avoid affecting
the
operation
of the
heater.
After
allowing
the
heater
to
cool, remove
the
front cover
panel.
(See
Step

previous section.) After
the
object
has
been removed, replace
the
front cover before
attempting
to
re-start
the
heater.
Cleaning
the
Cabinet
When
the
cabinet
is
soiled, wipe
it
with
a
damp cloth.
Restore
the
shine with
a dry
cloth.
The use of
abrasive
household cleaners
may
dull
the
finish.
CAUTION:
Checking
the
Flue Pipe
At
the
beginning
of
each
heating
season,
check
the
inside
of the
flue pipe. Foreign matter, spider webs,
etc.
must
be
removed.
Be
sure
all
fittings
and
joints
are
tight.

Reassembly
and
Reseating
of the
Vent-Air

Pipes
Make
sure that
all
exhaust
pipe

the
guard clean
at
least once
a
week.
