SECTION IV: INSTALLATION
WIRING
All electrical wiring and connections must be in accordance with local codes. In the absence
of local codes, wiring must conform to the National Electric Code ANSI/NFPA No. 70 or the
Canadian Electrical Code C22.1. This water heater must be electrically grounded. Electrical
power should be supplied through a fused disconnect switch located near the water heater.
Where local codes permit, use the supplied power cord for field connection. A grounding
receptacle is required.
If local codes do not permit the use of the supplied cord, the cord may be replaced with a
conduit connection. With the water heater unplugged, remove the strain relief bushing from
the upper jacket of the water heater. Disconnect the power cord from the wire nut connection
inside the junction box, (located on the control panel). Pull the power cord up through the
upper jacket and then out the hole where the strain relief was located. Run the (120V, 60 Hz)
power supply conduit up to the upper jacket hole, and secure in place. The new power cable
can then be routed to match the placement of the old cord, and run into the junction box for
final connections.
The water heater draws less than 5 amps (maximum). Check for proper polarity at the main
power connection prior to operating the water heater.
CAUTION
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 (including limits and
safeties) after servicing.
Component and schematic wiring diagrams are shown in Figures 32 and 33.
