Water Supply Connections
Refer to the illustration on right for
suggested typical installation. The
installation of unions or flexible
copper connectors is recommended
on the hot and cold water connections
so that the water heater may be
easily disconnected for servicing if
necessary. The HOT and COLD water
connections are clearly marked and
are 3/4
″
NPT on all models. Install a
shut-off valve in the cold water line
near the water heater.
The cold water connection, hot water
connection, and the temperature
and pressure relief valve may be
temporarily disconnected from the unit
to ease installation by loosening the
union hex nuts connecting the fittings
to the water heater. The connection of
these parts to the unit use seal rings to
form a water tight connection. Re-use
the rubber seal rings that are provided
with the heater when re-installing
the components. Do NOT use pipe
sealant on this joint. Do NOT torque
the union hex nuts to over 35 ft-lbs
when reinstalling the components.
Failure to properly reconnect the
fittings provided with the water heater
will void the manufacturer’s warranty.
SOLDER WITH CARE!!!
If
sweat connections are used, do NOT
apply heat directly to any component
directly connected to the water
heater. This includes the cold water
connection, hot water connection,
temperature and pressure relief valve
and the drain valve. Assemblies
should be built to a minimum length
of 12” before attaching to the water
heater to avoid damaging the unit.
!
WARNING:
Failure to follow the
instructions provided in this manual
may permanently damage the unit and
void the manufacturer’s warranty.
NOTICE: Do not
attempt to turn any
fitting connected to the
water heater union hex
nuts that are tightened.
Doing so will damage
the water heater and
void the manufacturer’s
warranty.
NOTICE: Auxiliary
catch pan MUST
conform to local codes.
The water heater should not be
located in an area where leakage of
the tank or connections will result in
damage to the area adjacent to it or to
lower floors of the structure. Where
such areas cannot be avoided, it is
recommended that a suitable catch
pan, adequately drained, be installed
under the water heater.
Under no circumstance will the
manufacturer be held liable for any
water damage in connection with
this water heater.
Catch pan kits are available from
the store where the water heater
was purchased, or any water heater
distributor.
