SECTION VIII: ELECTRICAL CONNECTIONS
WARNING
Turn OFF or disconnect the electrical power supply to the water heater before servicing. Label all wires
prior to disconnection when servicing controls. Wiring errors can cause improper and dangerous
operation. Verify proper operation after servicing.
All electrical wiring must be installed and grounded in accordance with local codes, or in the absence of
local codes, the National Electrical Code, ANSI/NFPA 70 and/or CSA C22.2 Electrical Code.
The water heater
must be
wired to a 120 VAC, 60 Hz, 15A power supply. The water heater
must be
wired on
a separate circuit and breaker. If a flexible line cord and plug is permitted by local code, then provide a three
wire grounding type receptacle within reach of the line cord provided on the control box.
Do
NOT
plug the line
cord into a receptacle that can have the power supply interrupted by a switch that is used to control lights or
another appliance.
If wiring in conduit is required, cut the line cord close to the control board and make the appropriate wiring
connections. Install an electrical conduit connector on the outside jacket of the water heater. Refer to the wiring
diagram for the correct connections to each wire lead.
CAUTION
This water heater
must
be wired on a separate circuit. Failure to wire on a separate circuit may cause
improper operation or failure of the electrical components of the water heater.
DO NOT
energize the electric circuit before the water heater tank is filled with water.
This controller is polarity sensitive. If the HOT and NEUTRAL supply voltage is reversed, the controller
will
NOT
sense flame and the water heater will
NOT
operate. Verify polarity before connecting the water
heater.
