TEMPERING

VALVE (SET TO

49°C (120°F))

1.Install a diaphragm-type expansion tank that is suitable for potable water on the cold water supply line. The expansion tank must have a minimum capacity of 5.7 litres (1.5 US gallons) for every 190 litres (50 US gal- lons) of stored water and be rated for 150 psi or the working pressure of the water heater.

2.Install a pressure relief valve rated at max 125 psi in the cold water supply line. Make sure the discharge of this valve is directed to an open drain and protected from freezing. Contact the local water supplier or plumbing inspector for information on how to control this situation.

Important: Do not plug the temperature and pressure relief valve.

Important: Always use a good grade of joint compound, approved for use with potable water systems, and be certain that all fittings are drawn up tight.

Important: Some models may contain energy saving heat traps to prevent the circulation of hot water within the pipes. Do not remove, modify or tamper with the heat traps or any inserts within the heat traps.

Please note the following:

DO NOT install this water heater with iron piping. The sys- tem should be installed only with new piping that is suitable for potable (drinkable) water such as copper, CPVC or poly- butylene. DO NOT use PVC water piping.

DO NOT use any pumps, valves or fittings that are not com- patible with potable water.

DO NOT use valves that may cause excessive restriction to water flow. Use full flow ball or gate valves only.

DO NOT use any lead based solder in potable water lines. Use appropriate tin-antimony or other equivalent material. DO NOT use with piping that has been treated with chro- mates, boiler seal or other chemicals.

DO NOT add any chemicals to the system piping that will contaminate the potable water supply.

Closed System/Thermal Expansion

Periodic discharge from the temperature and pressure relief valve may be due to thermal expansion in a closed water supply system. The water utility supply meter may contain a check valve. This will create a closed water system. During the heating cycle of the water heater, the water expands causing pressure inside the water heater to increase. This may cause the temperature and pressure relief valve to dis- charge small quantities of hot water. To prevent this from happening, there are two recommendations:

valve is dripping or leaking, have a

licensed plumber repair it.

• Do not plug valve.

• Do not remove valve.

• Failure to follow these instructions can

result in death or an explosion.

Refer to Figure 12 for a typical T&P valve installation. 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.
