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.
*Certain models do not have these connection assemblies shipped with the water heater. They (Part #9001262) are available
through the manufacturer. See “Repair Parts” section for ordering information.
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 peo-
ple 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 hard-
ware stores. Follow manufacturers instructions for
installation of these valves.
