
CAUTION: A relief valve is designed to discharge excessively hot
water. THE CUSTOMER IS RESPONSIBLE TO PROTECT
PROPERTY AND PERSONNEL FROM HARM WHEN THE
VALVE FUNCTIONS.

A ¾” NPT brass connection is provided on the topside of the heater for
the field installation of a relief valve (see Figure I).

Care must be taken to be sure that the stem of the pressure and
temperature relief is immersed in the water within the top 6” of the tank.

The drain line must not be concealed or blocked and must be protected
from freezing.

No valve of any kind should be installed between the relief valve and
tank or in the drain line.
E. WATER SUPPLY CONNECTIONS

All water supply fittings on this heater are brass. Do not over tighten or
strip threads.

The cold water fitting is a combination drain and inlet. It is not a shut off
valve.

Provide a shut off valve in the cold water line. Mark for future
emergency use.

Do not apply heat directly to the cold-water inlet.

The hot water outlet is a threaded connection to the tank. Do not over
tighten.

WARNING: Some local codes mandate the use of a backflow
preventer or check valve or pressure-reducing valve. An adequate
expansion tank (or other adequate means) must be installed to
prevent pressure build up or damage from thermal expansion when
a check valve or backflow preventer or pressure-reducing valve is
used. Failure to do so could result in tank leakage and therefore
void the warranty.
