PROPANE AND HIGH ALTITUDE
CONVERSION
KITS
It is very important to choose the correct kit and/or gas orifices for
the altitude
and the type of gas for which the furnace is being
installed.
Only use natural gas in furnaces designed for natural gas. Only use
propane (LP) gas for furnaces that have been properly converted to
use propane (LP) gas. Do not use this furnace with butane gas.
Incorrect gas orifices or a furnace
that has been improperly
con-
verted will create an extremely dangerous condition resulting in pre-
mature heat exchanger
failure, excessive
sooting,
high levels of
carbon monoxide,
personal injury, property damage, a fire hazard
and/or death.
High altitude and propane (LP) conversions
are required in order
for the appliance to satisfactory
meet the application.
An authorized distributor or dealer must make all gas conversions.
In Canada, a certified conversion station or other qualified agency,
using factory specified
and/or approved
parts, must perform the
conversion.
The installer must take every precaution to insure that the furnace
has been converted to the proper gas orifice size when the furnace
is installed.
Do not attempt
to drill out any orifices to obtain the
proper orifice size. Drilling out a gas orifice will cause misallgnment
of the burner flames, causing premature
heat exchanger burnout,
high levels of carbon monoxide,
excessive sooting, a fire hazard,
personal injury, property damage and/or death.

CONNECTIONS
1.
Provide a power supply
separate from all other circuits. Install
overcurrent
protection
and disconnect
switch per local/national
electrical codes. The switch should be close to the unit for conve-
nience in servicing. With the disconnect or fused switch in the OFF
position, check all wiring against the unit wiring label. Refer to the
wiring diagram in this instruction.
2.
Remove
the screws
retaining the wiring box cover. Route the
power wiring through the opening in the unit into the junction box
with a conduit connector or other proper connection.
In the junc-
tion box there will be three wires (a Black Wire, a White Wire and a
Green Wire). Connect the power supply as shown on the unit-wir-
ing label on the inside of the blower compartment
door or the wir-
ing schematic
in this section.
The black furnace
lead must be
connected
to the L1 (hot) wire from the power supply. The white
furnace lead must be connected to neutral. Connect the green fur-
nace lead (equipment
ground) to the power supply ground. An
alternate wiring method is to use a field provided 2" (5.1 cm) x 4"
(10.2 cm) box and cover on the outside of the furnace. Route the
furnace
leads into the box using a protective
bushing where the
wires pass through the furnace panel. After making the wiring con-
nections replace the wiring box cover and screws. Refer to Figure
12.
3.
The furnace's control system requires correct polarity of the power
supply and a proper ground connection. Refer to Figure 12.

Install the field-supplied
thermostat
by following
the instructions
that
come with the thermostat.
With the thermostat set in the OFF position
and the main electrical
source disconnected,
connect the thermostat
wiring from the wiring connections
on the thermostat
to the terminal
board on the ignition module, as shown in Figure 13. Electronic thermo-
stats may require the common wire to be connected
as shown with the
dashed line in Figure 13. Apply strain relief to thermostat wires passing
through cabinet. If air conditioning
equipment
is installed,
use thermo-
stat wiring to connect
the Y and C terminals
on the furnace
control
board to the yellow and brown wires on the condensing
unit (unit out-
side). Refer to Figure 13.
