Water Supply Connections - GE 30S BLM Serie Manuel D'utilisation

Installation Instructions

WATER SUPPLY CONNECTIONS

Refer to the illustration below for recommended installation. The HOT and COLD water connections are clearly
marked and are ¾" NPT on all models. When connecting to the inlet/outlet ports, the use of ¾" female NPT
tapered thread fittings with use of thread sealant is recommended. The installation of unions is recommended
on the hot and cold water
connections so that the
water heater may be easily
disconnected for servicing if
necessary. Piping should be
routed to allow anode rod
removal.
NOTE: Install a shut-off valve
in the cold water line near the
water heater. This will enable
easier service or maintenance
of the unit later.
IMPORTANT: Do not apply
heat to the HOT or COLD
water connections. If sweat
connections are used, sweat
tubing to adapter before
fitting the adapter to the cold
water connections on heater.
Any heat applied to the hot
or cold water connection
will permanently damage
the internal plastic lining in
these ports.
Install a vacuum relief valve
and/or anti-siphon device when
required by local jurisdictions.
HOT AND COLD PIPE INSULATION INSTALLATION (if
supplied with product)
For increased energy efficiency, some water heaters have
been supplied with two 24" sections of pipe insulation.
Please install the insulation, according to the illustrations
below, that best meets your requirements.
