PLEASE NOTE: MINI TANKS ARE FOR INDOOR PERMANENT INSTALLATIONS ONLY.
BEFORE POWERING THE WATER HEATER, BE SURE THAT THE SYSTEM IS COMPLETELY FILLED WITH WATER
AND ALL AIR IS REMOVED.

CLOSED SYSTEM THERMAL EXPANSION: Periodic discharge of the relief valve or
failure of the element gasket may be due to thermal expansion in a closed water
supply system. The water utility supply meter may contain a check valve, backflow
preventer or water pressure-reducing valve that will create a closed water system.
During the heating cycle of the water heater, the heated water expands causing
pressure inside the water heater to increase. The T&P relief valve may discharge
hot water under these conditions that result in a loss of energy and a build up
of lime on the relief valve seat. To prevent this from happening, there are two
recommendations:
1. Install a diaphragm-type domestic hot water expansion tank (suitable for
potable water) on the cold water supply line. The expansion tank must have a
minimum capacity of 1.5 U.S. gallons for every 50 gallons of stored water.
2. Install a 125-PSI pressure relief valve in the cold water supply line. Make sure
the discharge of this valve is directed to an open drain and protected from
freezing.
Included with your water heater is a 3/4 inch temperature and pressure relief
(T&P valve) valve that is certified by a nationally recognized laboratory. This
is designed to reduce the risk of excessive pressures and temperatures in this
water heater and should be installed as directed by local codes. The T&P valve is
marked with a maximum pressure, which does not exceed the maximum working
pressure of the water heater (150 psi).
Note
: If using a different temperature and pressure relief valve other than
the one provided with your purchase, please ensure that the maximum PSI
marking on the valve DOES NOT exceed the marked maximum working
pressure of the water heater.
1. Install the 3/4 inch T&P valve supplied with the water heater into the large
threaded opening located at the top of the water heater.
2. Attach a discharge pipe from the T&P valve terminating at a sink or drain. Do
not cap or plug the end of the dischage pipe.
