6.
Install a discharge line from the temperature and
pressure relief valve in the opening marked "T & P
RELIEF VALVE". Install as specifi ed under
"Temperature and Pressure Relief Valve".
7.
After piping has been properly connected to the
water heater, open the nearest hot water faucet.
Then open the cold water shut off valve and
allow the tank to completely fi ll with water. To purge
the lines of any excess air and sediment, keep the
hot water faucet open for 3 minutes after a constant
fl ow of water is obtained. Close the faucet and
check all connections for leaks.
Please note the following:
DO NOT install this water heater with iron piping.
The system should be installed only with piping that
is suitable for potable (drinkable) water such as
copper, CPVC, or polyethylene (PEX).
DO NOT use PVC water piping.
DO NOT use any pumps, valves, or fi ttings that are
not compatible with potable water.
DO NOT use valves that may cause excessive
restriction to water fl ow. Use full-fl ow ball or gate valves only.
DO NOT use tin-lead solder in potable water lines.
Use 95/5 tin antimony or other equivalent material.
DO NOT tamper with the Energy Saver Module (ESM),
electronic thermostat, temperature sensors, heating
elements, electrical connections, or temperature and
pressure relief valve. Tampering voids all warranties.
Only qualifi ed service 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.

Temperature-Pressure Relief Valve

This heater is provided with a properly certifi ed combination
temperature - pressure relief valve by the manufacturer.
The valve is certifi ed by a nationally recognized testing laboratory
that maintains periodic inspection of production of listed
equipment of materials as meeting the requirements for Relief
Valves for Hot Water Supply Systems, ANSI Z21.22 • CSA 4.4,
and the code requirements of ASME.
If replaced, the valve must meet the requirements of local codes,
but not less than a combination temperature and pressure relief
valve certifi ed as indicated in the above paragraph.
The valve must be marked with a maximum set pressure not to
exceed the marked hydrostatic working pressure of the water
heater (150 psi = 1,035 kPa) and a discharge capacity not less
than the water heater input rate as shown on the model rating
plate. (For electric heaters, watts x 3.412 equals Btu/hr input rate).
For safe operation of the water heater, the relief valve must not
be removed from its designated opening nor plugged.
The temperature-pressure relief valve must be installed directly
into the fi tting of the water heater designed for the relief valve.
Position the valve opening downward and provide tubing so
that any discharge will exit only within 6 inches above, or at any
distance below the structural fl oor. Be certain that no contact is
made with any live electrical part. The discharge opening must not
be blocked or reduced in size under any circumstances. Excessive
length, over 30 feet (9.14 m), or use of more than four elbows can
cause restriction and reduce the discharge capacity of the valve.
No valve or other obstruction is to be placed between the
relief valve and the tank. Do not connect tubing directly to
discharge drain unless a 6 inch air gap is provided. To prevent
