1GENERAL
Innovation (INN) Gas Fired Hot Water Boilers 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.
2Hot Water Boiler Electrical Requirements
Innovation Hot Water Boilers require the following electrical supply:
220 volts, single phase, 50 Hz, 15 Amps
Refer to Figure 1 for typical electrical shutoff 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. Voltages lower than the rated
input 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 of the unit.
Figure 2. Power Box and Terminal Block Location
All units that operate with a 220 VAC power source include a 220 VAC to 120 VAC transformer. This
transformer is installed inside the unit, as shown in Figure 3, and is pre-wired. The 220 VAC electrical
connection is made in the Power Box (see Figure 2).

3Provisions for Service
Designers must provide emergency shutoffs and other devices to satisfy electrical codes. It is also recommended
to provide an electrical shutoff disconnect switch of suitable load carrying characteristics on or near each Hot
Water Boiler. No electrical boxes or field components should be mounted to the surface of the unit or where they
would interfere with the removal of the side or top panels for maintenance. The disconnect switch should be
mounted near the unit as illustrated in Figure 1. Wiring conduit, EMT, or other wiring paths should not be secured
to the unit, but supported externally. Electricians should be instructed as to where the wiring conduit should be
located, such as away from the relief valve discharge, drains, etc. All electrical conduit and hardware should be
installed so that it does not interfere with the removal of any cover, inhibit service or maintenance, or prevent
access between the unit and walls or another unit.
4Unit Wiring
A dedicated protected circuit should be provided from the power source to the unit. No other electrical devices
should be permanently wired on the same circuit. An emergency switch (electrical shutoff) must be in series with
the power to the unit. Refer to Figure 4 for the wiring connections to the terminal block contained in the unit’s
Power Box.
5Multiple Unit Wiring
Whenever multiple units are installed within the same mechanical spaces, electrical code requirements call for a
single electrical shutoff for emergency use. It is the responsibility of the electrical designer to comply with local
codes and regulations affecting an individual installation.
