Table 8 or 9). However for installations above 5000 ft.
above sea level, a # 55 or #56 drill size orifice should be
used. After changing the orifices, use Table 7 to determine
the appropriate manifold pressure for your installation.
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 904090
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 904091
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.

WARNING:
To avoid electric shock, personal injury, or
death, turn off the electric power at the
disconnect or the main service panel before
making any electrical connections.
ELECTRICAL WIRING
General
Electrical connections must be made in accordance with all
applicable local codes and ordinances, and with the current
revision of the National Electric Code (ANSI/NFPA 70).
For Canadian installations the electrical connections and
grounding shall be done in accordance 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 temperature rating of at least 105°C. Refer to the
furnace nameplate and Table 10 for electrical requirements.
