Temperature=PressureRelief Valve

NOTE:Toprotectagainstuntimelycorrosionofhot and cold

water fittings, it is strongly recommended that di=electric

unions or couplings be installed on this water heater when

connected to copper pipe.

1.Look at the top cover of the water heater. The hot water outlet is marked hot. Put two or three turns of teflon tape around

the threaded end of the threaded-to-sweat coupling and around both ends of the 3/4" threaded nipple. Using flexible

connectors, connect the hot water pipe to the hot water outlet of the water heater.

2.Look at the top cover of the water heater. The cold water inlet is marked cold. Put two or three turns of teflon tape around

the threaded end of the threaded-to-sweat coupling and around both ends of the 3/4" threaded nipple. Using flexible

connectors, connect the cold water pipe to the cold water inlet of the water heater.

NOTE: Your water heater is insulated to minimize heat loss

from the tank. Further reduction in heat loss can be

accomplished by insulating the hot water lines from the water heater.

Fit T & P valve insulation over valve. Make sure that the insulation does not interfere with the lever of the T & P valve.

Secure all insulation using tape.

Remove insulation for T & P valve and pipe connections from carton.

Fit pipe insulation over the incoming cold water line and the hot

water line. Make sure that the insulation is against the top cover of the heater.

Explosion Hazard

"Tem perature-pressure relief valve must comply with ANSI Z21.22 CSA 4.4 andASMEcode.

Properly sized temperature-relief valve must be installed in opening provided.

"Can result in overheating and excessive tank pressure.

Can cause serious injury or death.

This heater is provided with a properly certified combination

temperature - pressure relief valve by the manufacturer.

The valve is certified by a nationally recognized testing

laboratory that maintains periodic inspection of production of

listed equipment of materials as meeting the requirements for Relief Valves for Hot Water Supply Systems, ANSI Z21.22 • CSA

4.4, and the code requirements of ASME.

If replaced, the valve must meet the requirements of local

codes, but not less than a combination temperature and

pressure relief valve certified as indicated in the above paragraph.

The valve must be marked with a maximum set pressure not to exceed the marked hydrostatic working pressure of the water heater (150 psi = 1,035 kPa) and a discharge capacity not less than the water heater input rate as shown on the model rating plate. (For electric heaters, watts x 3.412 equals Btu/hr input rate)

For safe operation of the water heater, the relief valve must not be removed from its designated opening nor plugged.

The temperature-pressure relief valve must be installed directly into the fitting of the water heater designed for the relief valve.
