Water Piping
The illustration shows the attachment of the water piping
to the water heater. The water heater is equipped with 3 ⁄

"
water connections .
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 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: 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 direct-
ly to the cold water inlet. It will harm the dip tube and
damage the tank.
NOTE: This water heater is super 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
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 manufacturers instructions
for installation of the valves. Before changing the facto-
ry setting of the thermostat, read the “Temperature
Regulation” section in this manual.
