Devices for Hot Water Supply Systems, ANSI Z21.22 - 
latest edition. This valve must be marked with the 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 fl oor, and does not contact 
any live electrical part. The discharge opening must not be 
blocked or reduced in size under any circumstance. 

IMPORTANT:  Only a new temperature and pressure relief 
valve should be used with your water heater. Do not use an 
old or existing valve as it may be damaged or not adequate 
for the working pressure of the new water heater. Do not 
place any valve between the relief valve and the tank.

The Temperature & Pressure Relief Valve:   

• 

Shall not be in contact with any electrical part.

• 

Shall be connected to an adequate discharge line.

• 

Shall not be rated higher than  the working pressure  
shown on the data plate of the water heater.

The Discharge Line:

• 

Shall not be smaller than the pipe size of the relief  
valve or have any reducing coupling installed in the 
discharge line.

• 

Shall not be capped, blocked, plugged or contain    
any valve between the relief valve and the end of the 
discharge line.

• 

Shall terminate a maximum of 6 inches above a floor 
drain or external to the building.

• 

Shall be of material listed for hot water distribution.

• 

Shall be installed to allow complete drainage of both 
the valve and discharge line.

Solar Installation

If this water heater is used as a solar storage heater or 
as a backup for the solar system, the inlet water supply 
temperatures to the water heater tank may be in excess of 
120°F. A tempering valve or other temperature limiting valve 
must be installed in the inlet water supply line to limit the 
supply temperature to 120°F.

NOTE: Solar water heating systems can often supply water 
with temperatures exceeding 180°F and may result in water 
heater malfunction.

Water Heater Location

  Centrally located with the water piping system.

  Located indoors and in a vertical position. Protected  

from freezing temperatures.

  Provisions made to protect the area from water    

damage. Metal drain pan installed and piped to an 
adequate drain.

  Sufficient room to service the water heater.

Water System Piping

  Temperature and pressure relief valve properly    

installed with a discharge line run to an open drain  
and protected from freezing.

  All piping properly installed and free of leaks.

  Heater completely filled with water. (See Figure 2)

  Closed system pressure buildup precautions    

installed.

  Tempering valve (when applicable) installed per 

manufacturer’s instructions (see “Water Temperature 
Regulation” section).

Electrical Connections

  Wiring and connections comply with all applicable  

codes.

  Water heater and electrical supply are properly    

grounded.

  Proper overload fuse or circuit breaker protection  

installed.
