CAUTION
The gas supply shall be shut off prior to disconnecting the
electrical power before proceeding with the conversion.
NOTICE
Do not remove the Low NOx screens from the heat
exchanger tubes.
1. Shut off gas supply at shutoff valve upstream of the unit or
at meter as required.
2. Remove the access panel to the gas heat compartment.
3. Carefully remove the wires from the gas valve, and note
their location so they may be properly replaced. Remove
the screws that hold the manifold to the manifold brackets,
and slide the manifold off the burners.
4. Remove the main burner orifices from the manifold, and
retain for future use.
5. Install the propane main burner orifices in the manifold, and
tighten them. After installing a propane orifice in each location, any leftover orifices may be discarded.
6. Reinstall the manifold in the assembly by reversing the
removal process.
7. Reconnect the wires to the proper terminals on the gas
valve.
8. When installing gas piping, insert tapped gas pipe nipple
(supplied with kit) into inlet fitting of gas valve. Tighten until
the 1/8 inch tapped hole in the gas pipe nipple is located in
the side facing outward toward where the door is to be
installed.
9. Install (thread) the gas line pressure switch (supplied with
kit) into the 1/8 NPT tapped hole in nipple applying pipe
joint compound to the switch fitting prior to installation.
Using a 7/16 inch open end wrench, tighten the switch making sure the connection does not leak. Electrical connections should be facing the right.
10. Rotate the tapped gas pipe nipple a 1/4 turn so the pressure switch is positioned on top of the gas pipe. Refer to
Figure 1.
NOTICE
The gas line pressure switch will cause the furnace to lock
out if the gas supply pressure drops below 6” w.c. The ignition control will display a fault code 7 and will reset after one
hour.
11. Disconnect the wire from the flame sensor.
12. Using the wire harness (supplied with kit) connect the wire
from the flame sensor into the insulated male connector;
connect the two 1/4” insulated terminals to the pressure
switch; and connect the remaining insulated flag terminal to
the flame sensor.
13. Convert the gas valve for LP (propane) gas operation by
following the instructions and using the components supplied in the envelope. Apply the label supplied in the kit to
the gas valve to show that it has been converted.

DANGER
PROPANE AND HIGH ALTITUDE CONVERSION KITS
Make sure that the correct kit and/or gas orifices for the altitude and the type of gas is used for the furnace installation.
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
converted will create an extremely dangerous condition
resulting in premature 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 satisfactorily 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 misalignment 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.

to Figure 2 for inlet pressure port location.
1. Turn gas and electrical supplies on, and follow the operating instructions to place the unit back in operation.

Maximum 10.5” W.C. (2.61 kPa) 13.0” (3.24 kPa) W.C.
IMPORTANT
The inlet gas pressure operating range table specifies what
the minimum and maximum gas line pressures must be for
the furnace to operate safely.
The gas line pressure

• 11” W.C. (2.74 kPA) for Propane (LP) Gas
in order to obtain the BTU input specified on the rating plate
and/or the nominal manifold pressure specified in these
instructions and on the rating plate.
2. Once the correct gas inlet pressure has been established,
refer to Table 1, turn the gas supply to OFF, and turn the
electrical supply switch to OFF; then remove the flexible
tubing from the gas valve pressure tap, and tighten the set
screw using the 3/32” (2.4 mm) hexagonal wrench.
3. Turn the electrical and gas supplies back on, and with the
burners in operation, check for gas leakage around the gas
valve pressure port for leakage using an approved non-corrosive gas leak detection fluid, or other non-flammable leak
detection methods.

Inlet and manifold gas pressure may be measured by connecting the “U” tube manometer to the gas valve with a piece of tubing. Follow the appropriate section in the instructions below.
Refer to Figure 2 for the locations of the pressure ports on the
gas valve.
Turn gas off at the ball valve or gas cock on gas supply line
before the gas valve. Find the pressure ports on the gas
valve marked Out P and In P.
1. The manifold pressure must be taken at the port marked
OUT P.
2. The gas inlet line pressure must be taken at the port
marked IN P.

IMPORTANT
The cover screw for the pressure regulator must be removed
entirely to gain access to the adjustment screw. Loosening or
tightening the cover screw does not adjust the flow of gas.

Gas Heating Value
Gas Heating Value
An overpressure protection device, such as a pressure regulator, must be installed in the gas piping system upstream of
the furnace and must act to limit the downstream pressure to
the gas valve so it does not exceed 0.5 PSI (14” w.c.) (3.48
kPa). Pressures exceeding 0.5 PSI (14” w.c.) (3.48 kPa) at
the gas valve will cause damage to the gas valve, resulting in
a fire or explosion or cause damage to the furnace or some of
its components that will result in property damage and loss of
life.

The following tests must be performed at the time of conver-
sion:
1. Connect a manometer to the manifold pressure tap on the
gas valve. Connect a power supply and a propane gas supply to the unit, if not already connected.
2. Turn on the propane gas supply, and bleed air from the gas
supply lines at a point as close to the inlet of the gas valve
as is practical. Move gas valve switch to the “ON” position.
3. Set the thermostat to call for “HEAT” or connect a jumper
between “R” and “W” on the ignition control board to simulate a call for heat.
4. Make sure unit electrical disconnect switch is in the “OFF”
position, and then energize the power supply to the disconnect switch.
5. Turn unit electrical disconnect switch “ON.” Verify that the
combustion blower starts and that the ignitor starts sparking.
6. Main burner ignition may be delayed on the first ignition
cycle due to air in the gas manifold.
7. Observe several ignition cycles. The main burners must
ignite without delayed ignition or burning at the orifices.
8. Adjust the manifold pressure in accordance with Table 2

in the following locations: gas valve inlet and outlet connections, manifold union in the burner compartment, and main
burner orifices where they thread into the manifold. Repair
any leaks found, and recheck. DO NOT CHECK WITH
OPEN FLAME.
10. With main burners off, disconnect the manometer, and

the manifold pressure setting could result in an over-fire
condition. A high manifold pressure will cause an over-fire
condition, which could cause premature heat exchanger failure. If the manifold pressure is too low, sooting and eventual
