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. 

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.

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.
