General Information
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 water piping.
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 valves only.
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 thermostat, 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
chromate's, boiler seal, or other chemicals.
DO NOT
add any chemicals to the system piping which
will contaminate the potable water supply.
8. Install a temperature and pressure relief valve and
discharge line in the opening marked "T & P RELIEF
VALVE". Install as specified under "Temperature and
Pressure Relief Valve."
9. After piping has been properly connected to the water
heater, open the nearest hot water faucet and allow
the tank to completely fill with water. To purge the
lines of any excess air and sediment, keep the hot
water faucet open for 3 minutes after a constant flow
of water is obtained. Close the faucet and check all
connections for leaks.
