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.

 

 

It is recommend that only

full flow

ball or gate valves

 

are used in water piping installations. 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.

Closed System/Thermal Expansion

Prope_y Damage Hazard

All water heaters eventual!y !eak

Do notinstallwithoutadequate drainage,

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 wilt 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

1.5U.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.
