pressure relief valve in accordance with local codes and ensure that it operates correctly and that
air is purged from the valve prior to installing the water heater. When connecting to Flex or High
Temperature CPVC pipe, we recommend that a T&P valve be used for added safety.
Please note: Installations in the Commonwealth of Massachusetts and State of Kentucky require
a pressure relief valve. Please check your local installation codes for any special requirements.
2. The maximum operating water pressure is 150 PSI. If the water pressure is higher, a pressure
reducing valve must be installed on the main incoming water supply line prior to installing the unit.
3. When connecting the inlet water pipe to the unit, make sure to use a wrench to hold the unit’s
connection, and another wrench to tighten, so the flow sensor on the unit is not loosened or
damaged. Serious internal damage to the water heater can occur if the inlet or outlet connections
are over tightened or if solder connections were made.
4. We recommend that a manual shut-off valve (ball valve) be installed on the inlet and outlet of the
water heater so there is a convenient shut-off point available in the event that future maintenance
or servicing is required. Before connecting pipes to the water heater, it is extremely important to
flush the lines to eliminate all plumbing paste or residue in the lines caused by any brazing or
soldering.
We recommend that all the water pipes or hoses within 3 feet of the inlet and outlet connections be rated
for high temperature applications with a 150°F minimum.
5- ELECTRICAL INSTALLATION
If further assistance is needed, a licensed and qualified electrician in accordance with all applicable
national, state, provincial, and local electrical codes should be hired. As with all electrical appliances, under
no circumstances should you attempt to install, repair or disassemble this water heater without first
shutting off all power to the unit directly at the fuse or breaker box.
Make sure to shut off all breakers.
SERIOUS BODILY INJURY OR DEATH CAN OCCUR IF YOU IGNORE THIS WARNING.
All wiring (wire gauge) and circuit protection (breakers) must comply with the U.S. National Electrical Code
(NEC) in the U.S.A., or the Canadian Electrical Code (CEC) in Canada. Failure to do so could result in
property damage and/or personal injury, and void your warranty. Note: The Canadian Electrical Code
generally requires that all supply wires and corresponding circuit protection used for domestic hot water
heating and hydronic heating applications be sized to a minimum of 125% of the maximum current rating
of the heater (see model specifications below for details).
Before installing this product, ensure that the home has sufficient electrical power available to handle the
maximum amperage load of the applicable model.
TURN OFF THE ELECTRICAL POWER BEFORE
PROCEEDING.
