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.
