Reliance Water Heaters 184123-000 - Manual (Page 9)

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
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.
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.
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 adaptor 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.

WATER PIPING PRESSURE TEST
This section is only for the manufacturer installing the
water heater when the installation is to comply with
H.U.D. Standards.
When testing the water ways, H.U.D. Standards state:
“Water distribution system. All water piping in the
water distribution system shall be subjected to a pres-
sure test. The test shall be made by subjecting the sys-
tem to air or water at 100 psi for 15 minutes without
loss of pressure. When air pressure is used, the water
heater shall not be connected during the test.”

WARNING
This water heater shall not be connected to any heating
systems or component(s) previously used with a non-
potable water heating appliance.
WARNING
If the water piping system is to be air pressure tested,
the water heater must be disconnected from the water
piping system. Failure to disconnect the water heater
during air pressure testing of the water piping system
could result IN DEATH, SERIOUS BODILY INJURY, OR
PROPERTY DAMAGE.
WARNING
HOTTER WATER CAN SCALD: Water heaters are
intended to produce hot water. Water heated to a tem-
perature which will satisfy clothes washing, dish wash-
ing, and other sanitizing needs can scald and perma-
nently injure you upon contact. Some people are more
likely to be permanently injured by hot water than oth-
ers. 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
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, 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 instructions for installation of the
valves. Before changing the factory setting on the ther-
mostat, read the “Temperature Regulation” section.
