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.
!
WARNING:
To avoid the risk of electrical shock, personal
injury, or death, disconnect all electrical power
to the unit before performing any maintenance
or service. The unit may have more than one
electrical power supply.
!
WARNING:
The unit cabinet must have an uninterrupted or
unbroken electrical ground to minimize personal
injury if an electrical fault should occur. This
ground may consist of electrical wire or approved
conduit when installed in accordance with
existing national or local codes.
ELECTRICAL WIRING
General — Electrical power wiring must be made in
accordance with all applicable local codes and ordinances,
and with the current revision of the National Electric Code
NFPA 70 or in Canada CSA C.22.1 Canadian Electrical
Code Part 1. If any of the original wire as supplied with the
unit must be replaced, it must be replaced with material of
the same gauge and temperature rating.
Line Voltage — Before proceeding with the electrical
connections, make certain that the voltage, frequency and
phase of the supply source are the same as those
specified on the unit rating plate. Also verify that the
service provided by the utility is sufficient to handle the
additional load imposed by this equipment.
This unit must be electrically grounded in accordance with
local codes or, in the absence of local codes, with the
National Electrical Code (ANSI/NFPA 70) or the CSA
C22.1 Electrical Code.
See Figure 10 or the unit wiring label for proper high and low
voltage wiring. Make all electrical connections in accordance
with all applicable codes and ordinances.
