areas.
10. Electrical
a. This appliance is designed to receive 208 V three phase power with a frequency
of 60 hertz — it is important that the supply voltage remains constant and that
low and high voltage conditions are avoided.
b. Size your wire in line with the amperage rating of the circuit, taking into account
derating for distances, see cable manufacturer rating for information or refer to
CSA C22.1 for additional information as a general reference:
i.
10 AWG to 50’
ii.
6 AWG to 100’
iii.
4 AWG to 200’

National Electrical Code, NFPA 70, or CSA C22.1, Canadian Electrical Code, Part I.
11. Gas Connections
a. Ensure gas connections are in compliance with the local authority having

b. Inlet gas train pressure must not exceed 14” W.C — sizing the gas regulation
equipment for this equipment is critical to safe and reliable operation.
c. Sizing of gas supply lines and proper sizing are critical, refer to CSA 149.1 for
proper line sizing based on your pressure.
d. After installation, check the manifold gas assembly for gas leaks by applying a
water and soap solution to each connection and observing for bubbles, note in
colder weather it is recommended to use a cold weather rated solution
