Electrical Wiring; Line Voltage Wiring - Nordyne VG7TC-FS Installation Instructions Manual

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 assembly in 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. above 2,000 ft., refer to
Table 11 (page 37) to determine the correct orifice size
and regulator pressure. See the example below.
When conversion is complete, verify the manifold pressure
and input rate are correct as listed in the Tables.
Installation Example
Elevation: ............................................... 5,000 feet
Type of Gas: ........................................... Propane Gas
Input BTUH of Furnace: ......................... 80,000
From Table 11, find 5,000 and follow across the row; stop
at the 80,000 btuh column. At first stage, the manifold
pressure listed is 4.2, but at 2nd stage the pressure is
9.0. The listed orifice size is 56..

and grounding shall comply with the current Canadian
Electrical Code (CSA C22.1 and/or local codes).

Line Voltage Wiring

It is recommended that the line voltage (115 VAC) to
the furnace be supplied from a dedicated branch circuit
containing the correct fuse or circuit breaker for the furnace.
See Table 5, (page 25).
