General Information

This kit is for conversion of furnaces equipped with Honeywell
SV9540 Series 2-stage gas valves certified for use with Natural
Gas (and so marked) to units functionally the same as the certified
furnace for use with Propane Gas. Before the furnace can be
operated with LP Gas, the LP low pressure must be installed (90+
models ONLY). A gas valve conversion kit must be installed and
main burner orifices and pilot burner orifice must be replaced with
orifices in this kit or with properly sized orifices for high altitude
ordered separately.

The orifices provided in this kit are stamped to indicate the size
(twist drill number) and are sized for commercially pure propane

gas ONLY. Do NOT use them with butane or a mixture of butane
and propane gas, or at elevations above 2000'. The parts list

specifies the size orifices supplied in the kit. Compare the size
marking on the orifices with the sizes as listed in the parts list.
Make sure you have the correct main burner orifices.

Extreme care is used to assure that this kit contains the proper
orifices. Oversized orifices could result in hazardous

conditions, especially if the venting is inadequate. For that
reason, we recommend that the installer check the size of the

orifice with a new twist drill of the correct size. This procedure
assures that the orifices provided are the correct size.

D Shut off gas supply to furnace at manual shut-off valve

before starting installation.

D Disconnect electric power supply to the furnace before

starting installation.

D Check for gas leaks after installation of kit and before

attempting to start furnace.

D Locate the LP Gas Conversion Label next to the furnace

rating plate.

D Fill out and attach the Field Conversion Label to the front

exterior of the furnace.

Gas Pressure

D Refer to the furnace rating plate for the approved gas input

ratings.

D Gas input to burners MUST NOT exceed the rated input

shown on rating plate.

D Do NOT allow minimum gas supply pressure to vary

downward. Doing so will decrease input to furnace. Refer
to Table 1 for gas supply and manifold pressures.

• With Propane gas, the rated input is obtained when the
BTU content is 2,500 BTU per cubic foot and manifold
pressure set at 10 inches W.C.

• If Propane gas has a different BTU content, orifices
MUST be changed by licensed Propane installer.

• Measured input can NOT exceed rated input.

• Combustion Air Box Cover MUST be removed when ad-

justing manifold pressure.

• Any major change in gas flow requires changing burner
orifice size.

Turn OFF gas supply at manual gas valve before
turning OFF electric power supply and starting

installation.
Turn OFF electric power supply at disconnect

switch or service panel before starting installation.
Failure to follow this warning can result in death,

personal injury, property damage and/or
equipment damage.

Disassembly

Refer to Figure 1 and the following steps.

1. After disconnecting power and gas supply to the furnace,
remove the access door, exposing gas valve and burner
compartment.

2. Disconnect gas line from gas valve so manifold assembly
can be removed.

3. Remove screws securing burner compartment cover and
remove cover. Use care to avoid damage to gasket. (if

used)

4. Disconnect wiring at gas valve. Be sure to note the proper
location of any and all electrical wiring disconnected.

5. Remove the pilot supply line from the gas valve.

6. Remove the screws holding the manifold and gas valve to
the manifold supports. Do Not discard any screws.

the four (4) screws holding the manifold supports to the front

partition and remove the NOx inserts. Replace the screws
that secure the NOx inserts and discard the NOx inserts.

These units may be installed at full input rating when installed at
altitudes up to 2000'. The #54 burner orifices supplied in this kit are
sized for commercially pure propane gas only, for use between

0-2000' elevation. Do not use them with butane or a mixture of
butane and propane, or at elevations above 2000'.

When installed above 2000', the input MUST be derated by 4% for
each 1000 feet above 2000'. Orifices for conversion at high

altitude (2000' - 8000') must be ordered from Service Parts. A #55
orifice is indicated for use between 2000' and 7000', and a #56

orifice is indicated for altitudes in the 7000' - 8000' range. Refer to
the parts list provided to determine the proper orifice part number
for ordering purposes.
