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.
Figure 3 shows the typical attachment of the water piping to the water
heater. The water heater is equipped with 3/4 inch NPT water connections.
NOTE: If using copper tubing, solder tubing to an adapter before
attaching the adapter 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 pressure test. The test shall
be made by subjecting the system 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.”
