Temperatures and Pressure Relief Valve
Caution! Install the Temperature/Pressure Relief Valve supplied with the water heater!
Install a discharge pipe from the temperature/pressure relief valve terminating at a sink or drain. Do not
cap or plug the end of the discharge pipe. The discharge pipe must be unobstructed and full sized.
The T/P valve is certied by a nationally recognized test lab that maintains periodic inspections of the
listed equipment and meets the requirements for relief valves and automatic shut off devices for hot
water supply systems ANSI 121.22-1979. The T/P valve is marked with a maximum pressure, which does
not exceed the maximum working pressure of the water heater (150 PSI). Install the T/P valve into the
threaded opening at the top of the water heater using heavy duty Teon tape. Do not over tighten! Orient
the discharge tubing so that any discharge from the valve will exit within 6 inches above, or at any distance
below the structural oor, and cannot contact any live electrical part.
T/P Valve Discharge Pipe
1. Must not be smaller in diameter than the outlet diameter of the valve, or have any reducing
