Please note the following:

•The system should be installed only with piping that is suitable for potable (drinkable) water such as copper, CPVC, or polybutylene. This water heater must not be installed using iron piping or PVC water piping.

•Use only pumps, valves, or fittings that are compatible with potable water.

•Use only full flow ball or gate valves. The use of valves that may cause excessive restriction to water flow is not recommended.

•Use only 95/5 tin-antimony or other equivalent solder. Any lead based solder must not be used.

•Piping that has been treated with chromates, boiler seal, or other chemicals must not be used.

•Chemicals that may contaminate the potable water supply must not be added to the piping system.

Closed System/Thermal Expansion

WARNING

Explosion Hazard

If the temperature and pressure relief valve is dripping or leaking, have a qualified person replace it.

Examples of a qualified person include:￿ licensed plumbers, authorized gas company personnel, and authorized service personnel.

Do not plug valve. Do not remove valve.

Failure to follow these instructions can result in death, or explosion.

Periodic discharge of 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, backflow preventer or water pressure reducing 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 discharge small quantities of hot water. To prevent this, it is recommended that a diaphragm-type expansion tank (suitable for potable water) be installed on the cold water supply line. The expansion tank must have a minimum capacity of 1.5 U.S. gallons for every 50 gallons of stored water. Contact the local water supplier or plumbing inspector for information on other methods to control this situation.

IMPORTANT: Do not plug or remove the temperature and pressure relief valve.
