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
