This water heater shall not be connected to any heating
systems or component(s) used with a non-potable water
heating appliance.
If a water heater is installed in a closed water supply sys-
tem; such as one having a back-flow preventer, check
valve, water meter with a check valve, etc. in the cold
water supply; means shall be provided to control thermal
expansion. Contact the water supplier or plumbing con-
tractor on how to control this situation.
NOTE: To protect against untimely corrosion of hot and
cold water fittings, it is strongly recommended that dielec-
tric unions or couplings be installed on this water heater
when connected to copper pipe.
The illustration shows the attachment of the water piping to
the water heater. The water heater is equipped with 3 /
4
inch
water connections.
NOTE: If using copper tubing, solder tubing to an adapter
before attaching the adapter to the cold water inlet con-
nection. Do not solder the cold water supply line directly
to the cold water inlet or it will harm the dip tube.
NOTE: This water heater is insulated to minimize heat loss
from the tank. Further reduction in heat loss can be
accomplished by insulating the hot water lines from the
water heater.

WARNING
HOTTER WATER CAN SCALD: Water heaters are intend-
ed to produce hot water. Water heated to a temperature
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 physical-
ly/mentally 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 addition to using the lowest possible tem-
perature setting that satisfies your hot water needs, some
type of tempering device, 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 manufacturers instruc-
tions for installation of the valves. Before changing the
factory setting on the thermostat, read the “Temperature
Regulation” section in this manual.
