This appliance has been design certified as complying with American National Standard/CSA Standard for water heaters and is considered suitable for:

Water (Potable) Heating: All models are “considered suitable for water (potable) heating.”

Water (Potable) Heating and Space Heating: Certain models are “considered suitable for water (potable) heating and space heating.” Refer to the model and rating plate of the water heater.

WARNING

When the system requires water at temperatures higher than required for other uses, the hot water system may require a means such as a mixing valve to be installed to temper the water at certain points of use. Some people are more likely to be permanently injured by hot water than others; these include the elderly, children, the infirm, or the physically/mentally handicapped. Before immersing yourself or anyone else in hot water, be sure to check the water temperature. WARNING: HOTTER WATER INCREASES THE RISK OF SCALD INJURY. (Also see “Temperature Regulation” section) Mixing valves are available at plumbing supply or hardware stores. Follow manufacturers instructions for installation of these valves.

WARNING

This water heater shall not be connected to any heating systems or component(s) previously used with a non- potable water heating appliance.

If this water heater is also used for space heating applica- tions, all piping and components connected to the water heater shall be suitable for use with potable water.

WARNING

Toxic chemicals such as used for treatment of boilers or non-potable water heating appliances shall never be introduced into a potable water space heating system.

NOTE: To protect against untimely corrosion of hot and cold water fittings, it is strongly recommended that di-electric unions or couplings be installed on this water heater when connected to copper pipe.
