Please note the following:
DO NOT install this water heater with iron piping.
The system should be installed only with new piping
that is suitable for potable (drinkable) water such as
copper, CPVC, or polybutylene. DO NOT use PVC
DO NOT use any pumps, valves, or fittings that are
not compatible with potable water.
DO NOT use valves that may cause excessive
restriction to water flow. Use full flow ball or gate
DO NOT use 50/50 tin-lead solder (or any lead
based solder) in potable water lines. Use 95/5 tin-
antimony or other equivalent material.
DO NOT tamper with the electronic control board,
temperature sensors, heating elements, electrical
connections, or temperature and pressure relief
valve. Tampering voids all warranties. Only qualified
technicians should service these components.
DO NOT use with piping that has been treated with
chromates, boiler seal, or other chemicals.
DO NOT add any chemicals to the system piping
which will contaminate the potable water supply.
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, backfiow 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 from
happening, there are two recommendations:
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 1.5 U.S. gallons for every 50 gallons of
Install a 125 PSI pressure relief valve 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. Do not plug the temperature
