
The condensate drain is at atmospheric pressure (non‐pressurized) and
therefore must be allowed to drain freely with gravity only. Please ensure
that there are no blockages along the condensate drain tube. All portions of
the condensate drain (neutralizer and drain tube) must be at a lower
elevation than the water heater to prevent condensate water from building
up inside the heat exchanger.

Condensate cannot be effectively neutralized if the neutralizer elements
inside the Neutralizer accessory have been completely consumed. If this
happens, Condensate will remain acidic and can possibly cause damage to
items such as pipes, concrete, etc., if drained improperly.

The Neutralizer cartridge is designed to last for 3 years before replacement.
However, the actual life of the neutralizer may vary, depending on the
application and usage. Please ensure that the cartridge is properly replaced
before the neutralizer elements have been completely consumed.

All preventative measures and safety practices must be adhered to when
draining condensate. The manufacturer will not be responsible for any
damage caused by condensate.

A drain pan, or other means of protection against water damage, is required
to be installed under the water heater in case of leaks.
Follow the electrical code requirements of the local authority having
jurisdiction. In the absence of such requirements, follow the latest edition of
the National Electrical Code ANSI/NFPA 70 in the U.S. or the latest edition of
CSA C22.1 Canadian Electrical Code, Part 1, in Canada.
When servicing or replacing parts within the water heater, label all wires
prior to disconnection to facilitate an easy and error‐free reconnection.
Wiring errors can cause improper and dangerous operation. Verify proper
operation after servicing.
ELECTRICAL CONNECTIONS
1. The water heater must be electrically grounded. Do not attach the ground wire to either the gas or
the water piping.
2. The water heater requires 120 VAC / 60 Hz electrical power supply that is properly grounded.
 A proper disconnect (i.e. on/off switch, power plug, etc.) controlling the main power to the
water heater must be provided for service reasons. (Must comply with local codes).
 Connect the power supply to the water heater exactly as shown in the wiring diagram;
3. A green screw is provided in the junction box to ground the connection.
4. Can be hardwired or wired to a plug‐in.
5. The use of a surge protector is
recommended in order to
protect the unit from power
surges.
