Conversion to LP/propane, sea level, and high
altitude is detailed in the installation instructions
provided with the conversion kit. Approved
conversion kits are listed below.
United States LP/Propane Gas Sea Level and
High Altitude Conversion Kit - P/N 903616
This kit is for LP/propane conversion in the
United States at altitudes between zero and
10,000 ft. above sea level. Follow the installation
instructions supplied with the kit for proper
installation.
Canadian LP/Propane Gas Sea Level and High
Altitude Conversion Kit - P/N 903617
This kit is for LP/propane conversions in Canada
at altitudes between zero and 4500 ft. above sea
level. Follow the installation instructions supplied
with the kit for proper installation.

CAUTION:
To avoid electric shock, personal in-
jury, or death, turn off the power at the
disconnect or the main service panel
before making any electrical connec-
tions.
ELECTRICAL WIRING
Electrical connections must be made in accor-
dance with all applicable local codes and ordi-
nances, and with the current revision of the
National Electric Code (ANSI/NFPA 70).
For Canadian installations electrical connec-
tions and grounding must be done in accor-
dance with the current Canadian Electrical Code
(CSA C22.1 Part 1) and/or local codes. If any of
the original wire as supplied with the furnace
must be replaced, it must be replaced with wire
having a minimum temperature rating of 105°C.
Refer to the furnace nameplate and Table 11 for
electrical requirements.
Line Voltage Wiring
The line voltage (115 volt) to the furnace must be
supplied from a dedicated branch circuit con-
taining the correct fuse or circuit breaker for the
furnace. See Table 11. An electrical switch
should be readily accessible from and within
sight of the furnace. (See the Wiring Diagram
label in the furnace and Figure 23.)
The furnace cabinet must have an uninterrupted,
unbroken ground to minimize injury should an
electrical fault condition occur. The controls
