Converting From Natural Gas To Lp / Propane; Electrical Wiring - Nordyne SC Installation Instructions Manual

Converting from Natural Gas to LP / Propane

WARNING:
The furnace was shipped from the factory
equipped to operate on natural gas.Conversion
to LP / Propane gas must be performed by
qualified service personnel using a factory
supplied conversion kit. Failure to use the
proper conversion kit can cause fire, explosion,
property damage, carbon monoxide poisoning,
personal injury, or death.
Conversion to LP / Propane is detailed in the installation
instructions provided with the conversion kit. Generally,
this will require the replacement of the burner orifices and
the spring found under the cap screw on the pressure
regulator. Approved conversion kits are listed below:
• Installations in the United States: For Propane (LP)
conversion or for LP gas installations in altitudes between
2,000 ft. and 10,000 ft. above sea level, use the LP &
High Altitude LP Gas Conversion Kit (P/N 904914) for
Installations in the United States. Please follow the
instructions provided with the kit.
• Installations in Canada: For Propane (LP) conversion or
for LP Gas installations in altitudes between zero and
4,500 ft. above sea level, use the LP & High Altitude
LP Gas Conversion Kit (P/N 904915) for Installations
in Canada. Please follow the instructions provided
with the kit.
If the installation is in the U.S. and above 2,000 ft., refer
to Table 12 (page 41) to determine the correct orifice
size and regulator pressure. See example below.
When conversion is complete, verify the manifold pressure
and input rate are correct as listed in the table.
Installation Example
Elevation: ............................................5,000 feet
Type of Gas: .......................................Propane Gas
Input BTUH of Furnace: ......................72,000
From Table 12, find 5,000 and follow across the row,
stop at the 72,000 btu column. The manifold pressure
listed is 10.0 and the orifice size is 57.
