This appliance has been design certified as complying with American National Standards 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." Referto the model
and rating plate of the water heater.
AWARNING
HOTTER WATER CAN SCALD: Water heaters are
intended to produce hot water. Water heated to a tem-
perature which will satisfy clothes washing, dish washing,
and other sanitizing needs can scald and permanently
injure you upon contact. Some people are more likely to
be permanently injured by hot water than others. These
include the elderly, children, the infirm, or physically/men-
tally handicapped. If anyone using hot water in your home
fits into one of these groups or if there is a local code or
state law requiring a certain temperature water at the hot
water tap, then you must take special precautions. In addi-
tion to using the lowest possible temperature setting that
satisfies your hot water needs, a means such as a mixing
valve, should be used at the hot water taps used by these
people or at the water heater. Mixing valves are available
at plumbing supply or hardware stores. Follow manufac-
turers instructions for installation of the valves. Before
changing the factory setting on the thermostat, read the
"Temperature Regulation" section in this manual.
_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
applications, 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 con-
nected to copper pipe.
