GENERAL
Innovation (INN) Gas Fired 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 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.
Heater Electrical Requirements
The Innovation water heater requires 120/1
∅
/60 Hz electrical supply. The distribution block for field
connection is located in the upper right of the control box. 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.
Refer to Figure 1 for typical service disconnect switch location. Figure 2 shows the location of the Power
Box containing the terminal block connections. The Power Box is accessed by opening the front panel
door of the unit
