State GS6 65 XRRT - Manual (Page 9)

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 check valve, etc. in the cold
water supply, means shall be provided to control thermal
expansion. Contact the water supplier or plumbing
inspector on how to control this situation.
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.
The illustration shows the attachment of the water piping
to the water heater. The water heater is equipped with 3 ⁄
4
″
water connections.
NOTE: If using copper tubing, solder tubing to an
adapter before attaching the adapter to the cold water
inlet connection. Do not solder the cold water supply
line directly to the cold water inlet. It will harm the dip
tube and damage the tank.

WARNING
HOTTER WATER CAN SCALD: Water heaters are intended 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 physically/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 tempera-
ture water at the hot water tap, then you must take special
precautions. In addition to using the lowest possible tempera-
ture 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 man-
ufacturers instructions for installation of the valves. Before
changing the factory setting on the thermostat, read the
“Temperature Regulation” section in this manual.
