1 General Information

Innovation-Edge (INN) Water Heaters are fully factory wired and packaged units which require simple
power wiring as part of the installation. This technical guide is intended to help designers provide
electrical power wiring (line voltage) to Innovation-Edge units. Control wiring details are provided in
other publications depending on the intended application. This document is intended as a guide only,
and cannot include all alternatives, situations, or be totally inclusive. To comply with all codes and
authorities having jurisdiction, designers and installers must plan the electrical wiring carefully and
execute the installation completely. Emergency shutoffs, fusible fire switches, break glass stations,
and other electrical requirements should be considered and installed whenever necessary.

2 Electrical Requirements

Innovation-Edge water heaters require one of the following input power:

• 120 volts, single phase, 50/60 Hz, 20 Amps

• 220 volts, single phase, 50/60 Hz, 10 Amps

Refer to Figure 1 for typical Service Disconnect Switch location.

Figure 1. Service Switch Typical Location

The distribution block for field connection is located in the upper right of the control box (see Figure 2).
All copper wire must be connected to the terminal distribution block. 110 VAC is the minimum
allowable supply voltages to the unit. Lower voltages will result in increased wear and premature
failure of the blower motor. Wire size and type should be made per the National Electrical Code based
on length and load.

Figure 2 shows the location of the Power Box containing the terminal block connections. The Power
Box is accessed by removing the front panel door of the unit.
