American Water Heater 318935-003 installation instructions Closed System/Thermal Expansion

Page 13

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.

As water is heated, it expands (thermal expansion). In a closed system, the volume of water will grow. As the volume of water grows, there will be a corresponding increase in water pressure due to thermal expansion. Thermal expansion can cause premature tank failure (leakage). This type of failure is not covered under the limited warranty. Thermal expansion can also cause intermittent temperature-pressure relief valve operation: water discharged from the valve due to excessive pressure build up. The temperature-pressure relief valve is not intended for the constant relief of thermal expansion. This condition is not covered under the limited warranty.

A properly-sized thermal expansion tank should be installed on all closed systems to control the effects of thermal expansion. Contact a plumbing service agency or your retail supplier regarding the installation of a thermal expansion tank.
