ELECTRICAL CONNECTIONS
1. The water heater requires 120 VAC, 60 Hz electrical power supply that is properly grounded.
2. The use of a surge protector is recommended in order to protect the unit from power surges.
Follow the electrical code requirements of the local authority having jurisdiction.
In the absence of such requirements, follow the latest edition of CSA C22.1
Canadian Electrical Code, Part 1.
WARNING
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.
CAUTION
• 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.
