Installation Instructions
WATER SUPPLY CONNECTIONS
Referto the illustrationbelow for suggestedtypical 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 easilydisconnected for servicingif
necessary.The HOTand COLDwater connections are clearly
marked and are 3/4" NPTon all models.
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.

CONDENSATION DRAIN TUBES
This unit has a condensation tray. Thewater collected in the
tray drains out of the sideof the unit. It is important to install a
drain pipe to the primary drain port coming off the sideof the
unit Plumbone end to the lower drain port on the sideof the
unit. Plumbthe other end to a drain in the floor or no higher
than :3'(0.9m) above the floor. If such drain is unavailable,
a condensate drain pump (not
provided)must be purchased and
installed.The drain pipe should be
routed sothat the discharge water
cannot contact live electricalparts
or persons and to eliminate potential
water damage.
RELIEF VALVE
A WARNING: Risk o u,,it o o og -The
pressure rating of the relief valve must not exceed 150
PSI(1.03 kPa),the maximum working pressure of the
water heater as marked on the rating plate.
A new combination temperature and pressure-relief
valve, complying with the Standard for ReliefValves and
Automatic Gas Shut-Off Devicesfor Hot Water Supply
Systems,ANSIZ21.22, is supplied and must remain installed
in the opening provided and marked for the purpose on
the water heater. No valve of any type should be installed
between the relief valve and the tank. Local codes shall
govern the installation of relief valves.
The BTUHrating of the relief valve must not be lessthan the
input rating of the water heater as indicated on the rating
label located on the front of the heater (1 watt=3.412 BTUH).
Connect the outlet of the relief valve to a suitable open drain
so that the discharge water cannot contact live electrical
parts or persons and to eliminate potential water damage.
Piping used should be of a type approved for hot water
distribution. The discharge line must be no smaller than the
outlet of the valve and must pitch downward from the valve
to allow complete drainage (by gravity) of the relief valve
and discharge line.The end of the discharge line should
not be threaded or concealed and should be protected
from freezing. No valve of any type, restriction or reducer
coupling should be installed in the discharge line.
A CAUTION:
To reduce the risk of excessive pressures and
temperatures in this water heater, install temperature
and pressure protective equipment required by local
codes and no less than a combination temperature and
pressure relief valve certified by a nationally recognized
testing laboratory that maintains periodic inspection of
production of listed equipment or materials, as meeting
the requirements for Relief Valves and Automatic Gas
Shutoff Devices for Hot Water Supply Systems, ANSI
Z21.22. This valve must be marked with a maximum set
pressure not to exceed the marked maximum working
pressure of the water heater. Install the valve into an
opening provided and marked for this purpose in the
water heater, and orient it or provide tubing so that
any discharge from the valve exits only within 6 inches
above, or at any distance below, the structural floor, and
does not contact any live electrical part. The discharge
opening must not be blocked or reduced in size under
any circumstances.
