• 

 Must be connected to an adequate discharge line.

• 

 Must not be in contact with any electrical part.

• 

 Must not be rated higher than the working pressure

 

 shown on the data plate of the water heater.

• 

 Must not be smaller than the pipe size of the relief

 

 valve or have any reducing coupling installed in the

 

 discharge line.

•    Must not be capped, blocked, plugged, or contain

 

 any valve between the relief valve and the end of 

 

 the discharge line.

• 

 Must terminate a maximum of six inches above a

 

 fl oor drain or external to the building. In cold climates,  

 

 it is recommended that the discharge pipe be termi- 

 

 nated at an adequate drain inside the building.

•    Must be capable of withstanding 250° F (121°

 

C)

 

 without distortion.

•    Must be installed to allow complete drainage of

 

 both the valve and discharge line.

1.  Locate the temperature and pressure relief valve on 

the water heater (also known as a T&P Relief Valve, 

(Figure 6). 

2.  Locate the slit running the length of the insulation.
3  Spread this slit open and slip it up under the T&P 

Relief Valve (See Figure 6). Apply gentle pressure to 

the insulation to ensure it is fully seated on the T&P 

Relief Valve.  Once sealed, secure the insulation with 

a section of duct tape, electrical tape, or equivalent.

IMPORTANT: The insulation or tape must not block 

the discharge opening or hinder access to the manual 

relief lever. Ensure a discharge pipe is installed into 

the T&P valve discharge opening per the instructions 

manual.

4.  Locate the hot water (outlet) & cold water (inlet) pipes 

to the water heater.

5.  Locate the slit running the length of a section of pipe 

insulation.

6.  Spread the slit open and slip the insulation over 

the cold water (inlet) pipe. Apply gentle pressure 

along the length of the insulation to ensure it is fully 

seated around the pipe. Also ensure that the base of 

insulation is flush with the water heater. Once seated, 

secure the insulation with duct tape, electrical tape, or 

equivalent.

7.  Repeat steps 5 through 6 for the hot water (outlet) 

pipe.

8.  Add additional sections of pipe insulation as needed.

  

If this water heater is used as a solar storage heater or

as a backup for the solar system, the water supply

temperatures to the water heater tank may be in excess

of 120° F (48.8° C). A mixing valve or other temperature 

limiting valve must be installed in the water supply line to 

limit the supply temperature to 120° F (48.8° C).
Note: Solar water heating systems can often supply water 

with temperatures exceeding 180° F (82.2° C) and may 

result in water heater malfunction.

If you lack the necessary skills required to properly

install the electrical wiring to this water heater, do not

proceed, but have a qualifi ed electrician perform the

installation.
When making the electrical connections, always make

sure:
•  

The electrical supply has the proper overload fuse

 

 or circuit breaker protection.

•  

Wire sizes and connections comply with all

 

 applicable codes.
