A
WARNING
If your
propane
gas furnace is
installed
in
a
basement, an
excavated
area or a con-
fined space,
we recommend that you
contact
your
propane
supplier about
installing a
warning
device that would
alert you to a
gas leak.
We
recommend
this because
propane gas is
heavier
than
air and
any leaking
gas
can
settle
in any
low areas
or
confined spaces. This pro-
pane
gas would create a
DANGER OF
EXPLOSION
OR
FIRE. If you suspect the
presence
of gas, follow
the instructions
on the
cover
of the
user's
manual.
ELECTRICAL
WIRING
A CAUTION
To avoid electrical shock, injury
or
death,
disconnect electrical
power
before
changing
any electrical
wiring.
The
wiring
harness on this
unit
is
furnished as an integral part
of
the
furnace. Field alteration to
comply
with electrical codes
should not be required.
Power supply to the furnace must be
N.E.C. Class
1,
and
must comply with all applicable codes. The
furnace
must be
electrically grounded in accordance with local codes or in
their absence, with the latest edition of the National Electrical
Code,
ANSI/NFPA
No. 70.
A
fused disconnect should be pro-
vided
and sized in accordance with the unit
minimum circuit
ampacity.
A CAUTION
Wiring to the unit must be properly
polar-
ized and grounded.

FURNACE
A 40VA transformer
and auxiliary
fan relay are built into the
fur-
nace so that it may
be used with most cooling equipment.
The furnace is designed
for
heating applications and
has
an
auxiliary fan relay built
in for use with cooling
equipment.
See the wiring diagram
for both 115v. and
24v. wiring details
and the
Heat Anticipator Setting. This is located
inside of the
blower
compartment
door
and

HEAT ANTICIPATOR
SETTING
The heat anticipator in
the
room
thermostat must
be
correctly
adjusted
to obtain the proper number of
heating cycles per
hour
and to
prevent the room temperature from
"overshoot-
ing"
the room thermostat setting. Heat
anticipator
must be
set at 0.8 amps.
GENERAL INFORMATION
This furnace is
equipped
with
a
self
diagnostic electronic
igni-
tion control which
lights the burners. It also has an induced
draft
blower
to draw combustion air
into the
heat
exchanger.
Keep the
blower
access door and
upper
access panel in
place
except for inspection
and maintenance. An interlock switch
pre-
vents furnace operation if
the
blower door
is not in place.
On new
installations or if a
functional
part such as the
gas
valve, pressure switch or fan/limit control
has been replaced,
the
operation of
the furnace should be checked.
Check
furnace operation as outlined in the following
instruc-
tions. If any sparking, odors,
or
unusual
noises are encoun-
tered, shut off electrical power and
recheck for
wiring errors, or
obstructions
in or near
the
blower
motors.
SELF
DIAGNOSTIC
IGNITION
CONTROL
In this furnace, there may be a
red
indicator
light
located
on
the
ignition control
board
near
the MV terminal. This
light is
designed to help the servicer
diagnose potential
service prob-
lems
with either
the furnace or the ignition control itself. If
the
furnace is malfunctioning,
and the red
light
is on continuously,
the
ignition
control is faulty. If
the red
light is flashing,
the fur-
nace is
probably
in a lock -out condition. If the indicator
light
is
not
on or flashing
and the
furnace
does not
operate properly
then
the
problem likely
exists elsewhere in the furnace
and not
in the ignition
control
board.
