maintained, it should give you years of trouble free service.
Abbreviations Found In This Instruction Manual:
• CSA - Canadian Standards Association
• ANSI - American National Standards Institute
• NFPA - National Fire Protection Association
• ASME - American Society of Mechanical Engineers
• GAMA - Gas Appliance Manufacturer’s Association
• UL - Underwriters Laboratories Inc.
This gas-fired water heater is design certified by Underwriters
Laboratories Inc. under American National Standard/CSA Standard
for Gas Water Heaters ANSI Z21.10.3 • CSA 4.3 (current edition).
preparInG for the InstallatIon
1. Read the “General Safety” section, page 3 and 4 of this manual
first and then the entire manual carefully. If you don’t follow the
safety rules, the water heater will not operate properly. It could
cause DEATH, SERIOUS BODILY INJURY AND/OR PROPERTY
DAMAGE.
This manual contains instructions for installation, operation, and
maintenance of the gas-fired water heater. It also contains warnings
throughout the manual that you must read and be aware of. All warnings
and all instructions are essential to the proper operation of the water
heater and your safety. Since we cannot put everything on the first
few pages, read the entIre Manual Before atteMptInG
to Install or operate the water heater.
2. The installation must conform with these instructions and the local
code authority having jurisdiction. In the absence of local codes,
installations should comply with the Natural Gas and Propane
Installation Code CAN/CSA B149.1 and the Canadian Electrical
Code CAN/CSA C22.1. These publications are available from the
Canadian Standards Association, 5060 Spectrum Way, Suite 100,
Mississauga, Ontario, Canada L4W 5N6.
3. The water heater when installed must be grounded in
accordance with the local codes, or in the absence of local
codes: the Canadian Electrical Code (C22.1).
4. If after reading this manual you have any questions or do not
understand any portion of the instructions, call the local gas utility
or the manufacturer whose name appears on the rating plate.
5. Carefully plan the place where you are going to put the water
heater. Correct combustion, vent action, and vent pipe installation
are very important in preventing death from possible carbon
monoxide poisoning and fires, see Figures 1 and 2.
Examine the location to ensure the water heater complies with
the “Locating the New Water Heater” section in this manual.
