PREPARING FOR THE INSTALLATION

1.Read the “General Safety” section, page 3 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 the installation, operation, and maintenance of the gas-fired water heater. It also contains warnings throughout the man- ual 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 lo- cal codes, installations shall comply with the “Natural Gas and Propane Installation Code” CAN/CSA-B149.1. This publication is available from the Canadian Standards Asso- ciation, 5060 Spectrum Way, Mississauga, Ontario, Canada, L4W 5N6.

3.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.

4.Carefully plan the place where you are going to put the water heater. Correct combustion, vent action, and vent pipe instal- lation 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.

5.In Earthquake Zones the water heater must be braced, an- chored, or strapped to avoid moving during an earthquake. Contact local utilities for code requirements in your area.
