INSTALLATION
DRAFT
HOOD
The
heater
has
a
draft
hood
built
into
its
back.
It
must
not
be
altered,
obstructed,
or
blocked
in
any
way,
and
the
unit
must
be
installed
so
that
the
draft
hood
is
in
the
same
atmospheric
pressure
zone
as
the
combus¬
tion
air
inlet
to
the
burner.
VENTING
This
heater
is
a
vented
appliance
and
must
be
con¬
nected
to
a
chimney/flue
in
accordance
with
the
installation
codes.
Note:
The
rear
cover
plate
is
only
attached
when
outside
air
is
being
used.
If
using
room
air
for
combustion,
remove
the
cover
plate
from
the
back
of
the
pedestal.
For
your
safety
this
heater
is
equipped
with
a
vent
safety
switch
designed
to
sense
incorrect
venting
and
react
by
shutting
down
the
gas
supply.
This
thermally
actuated
switch
is
located
within
the
draft
hood
and
will
detect
either
a
blocked
chimney
or
backdraft
condition
where
the
chimney
flow
has
reversed.
If
this
switch
is
closing
the
unit
down,
it
indicates
a
drafting
problem
-
the
thermally
actuated
switch
must
never
be
by-passed
or
disconnected
as
a
hazardous
or
deadly
condition
can
result.

four
inch
diameter

input.
However,
a
branch
fitting
(available
from
the
same
chimney

located
as
close
as
practical
to
the
chimney
can
be
used
to
connect
the
vent

appliance
to
that
of
the
vent
connector
of
the
other
