Installation
3.3 Water Supply Connections
Refer to the illustration below for recommended installation. The HOT and COLD water connections are
clearly marked and are 4" NPT on all models. When connecting to the inlet/outlet ports, the use of 3/4"
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.
NOTICE
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.
WARNING
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.
Conduit to Electrical Junction Box or optional power
cord installation. (use only copper conductors).
