INSTALLATION
1,1.
GENERAL
This
appliance
is
certified by
the Canadian
Gas
Association
for
installation
on
an
outside
wall
and
for
use
with
propane
gas
The
certification
includes installation
in
a
mobile
home.
The
installation
must
conform
with
local
codes.
In
the
absence
of
local
codes,
the
installation
must
conform
with
the
current
CAN/CGA-B149.2
installation
code
(Propane).
Installation
in
a
mobile
home
must
conform
to
the
current
standard
CSA
Z240.4
(Gas
equipped
recreational vehicles
and
mobile
housing).
This
appliance is
not
intended for
use
with
a
thermostat.
NOTE
Information
contained
in
this
booklet
applies
to
regular
home
and
mobile
housing
installations.
Only
qualified
(licensed or
trained)
personnel
should
install
the furnace.
1.2.
LOCATION
The
furnace
must
be
located
on an
outside
wall
which
has
a
total
thickness
between
3V 2 in
minimum and
1 51 / 2 in
maximum. The
vent
clearance
hole
is
7%in
diameter.
1.2.1.
INSIDE
THE
ROOM
Choose
a
room
location
against
an
outside
wall
which
will
allow
thefurnace to be
sited
as
shown
in figure
1.
Use
the
wall
plate unit
supplied
by
attaching
ittothewallpriortomountingthe

6”
centers
(see
fig
2).
The
weight
of
the
appliance
is
carried
on the
walt
plate
unit.
This
arrangement
is
0”
clearance
to
combustible
walls.
Facing
materials such
as
tile
or marble
up to
/“
thickness may
be
butted
against
the
wall plate
edges
to
form
a
decorative surround.
Additional
wall
finishes
thicker
than
3/4”
(eg
mantles)
must
be kept
to
the required
side
and
top
clearances
as in
Fig.
1.
Install only

hard
surfaced
materials. It
is
recommended
for
aesthetic
considerations
and
ease
of
maintenance that

THE
WALL
If
the
furnace
is
to
be
installed
directly on
carpeting,
vinyl
tile
or
other combustible
material
other
than
wood
flooring,
the
furnace
should
be
installed
on
a
hearth
extending
the
full
width and
depth
of
the
appliance.
Take
account
of
the
thickness
of
this
panel
when
marking
the vent
opening
position.
This
direct
vent appliance
is
designed
to
operate
when
an
undisturbed air
flow
hits
the
outside
vent
terminal
from
any
direction.
Minimum
clearances
from
this
terminal
which could
disrupt
the
air
flow
or
cause
a

are
shown
in

PREPARE
VENT
OPENING
The
vent
terminal must
not
be recessed
into
a
wall
or
siding.
The
vent
outlet should
also
be
positioned
where
it
will
not
be
covered
by
any
snowdrifts.
WARNING
If
the
outside
vent
terminal
is
to be
located
where
it
will
be
accessible
to
any
person,
a
guard
must
be
fitted
over
the
terminal
to
prevent
damage
to
the
vent and
to
prevent
it
being
touched.
The
vent
terminal
becomes
very
hot
in
use
and
could
cause
burns.
A
special
guard
is
available
from

IMPORTANT
Before
cutting
the
vent
opening
in the
wall
make
sure
that
the
finished
floor
level
is
known,
this
floor
level
must
include
any
loose
hearth
or
panel
which
will
be
fit’
ed
under
the
furnace.
Once
the
vent
opening
in
the
wall
is
cut
out
it will
not
be
possible
to
alter
the
position
of
the
furnace
without
recutting

and
203/5”
above
the finished
floor
level
(see fig.
4).
The
height
of
the
vent
hole
is
important.
If
it is
too
low,
it
will
be
impossible
to fit
the furnace
casing.
If it is
too
high,
the
fender

will
be
suspended
above
the
floor
(the
andirons can
be
adjusted
slightly
to
allow
for
a
small
inaccuracy
in the
height
of
the

A
rough
check
of
the
marked
position
can
be
made
by
placing

If possible,
while
still
maintaining
a
sound connection
to

collars, slope
the
vent unit down
slightly
away from
the
outside
wall
so
that any
rain
will
run
away
from
the furnace.
The
vent unit must
never
slope
upwards
from

line
must
be
sized and
so
installed
to
provide
a
supply
of
gas
sufficient
to
meet
the
maximum
demand
of
the furnace
without

Sealants
should
be
applied
lightly
to male

The supply
system should
include a manual

PRESSURE
RELIEF
UNIT
This
appliance
is fitted
with
a
pressure
relief
unit
as shown
in fig.
1 6.
The
purpose
of
this
unit
is
to
allow
a
safe
relief
of
pressure
n
the
unlikely
event
of
a
build
up
of
gas
in
the burner
compartment
before
ignition
takes
place.
Relief
is
attained
by
the
pressure
pushing
the
burner
access
panel
forward
against
the
springs
and
so
allowing
some
gas
to
escape
safely round
the
cover.
The
cover
will
then
return
to
its
original position.
Test
the
action
of
the
unit
by
pulhng
the
access
panel
forward
against
the
springs
and
allowing
it to
snap
back
into
position.
Make
surethatthe
panel
isfreeto
moveand
that
it
resets
to
the
original position.

(c)
While
still
holding
down
the
control

press
the
igniter
button
several
times
until
the
