Electrical Wiring, Millivolt System

ELECTRICAL WIRING

NOTE: If it is necessary to replace any of the original wiring, it must be replaced with 105 °C wire or its equivalent, except all black wire must be replaced with 150 °C wire or its equivalent.

MILLIVOLT SYSTEM

The Millivolt System Residential Heater is equipped with a self-generating electrical system in which the electric current is provided by means of a pilot generator. No external electrical connections are required.

ELECTRONIC INTERMITTENT IGNITION DEVICE SYSTEM (IID)

NOTE: When the electrical hookup to the heater requires both 24V and 115V or 240V, each input voltage must be isolated in separate conduit.

The Electronic Intermittent Ignition Device automati- cally lights the pilot and main burners upon a call for the heat. The heater is supplied with a dual voltage trans- former for 120V or 240V input power hookup.

NOTE: IID Propane Units Only

Heater is equipped with an electronic ignition device with a 100% safety lockout feature. If the heater fails to start or lockout. Reset the ignition device by interrupting the power to the heater for 60 seconds.

CAUTION: If service replacement of the electronic igni- tion device is required. Replace only with a 100% safety lockout device with 90 second trial for pilot ignition.

For 120 V input power to the unit, connect the black wire to the ÒL1Ó or hot leg of the power supply. Connect the white wire to the ÒL2Ó or neutral leg of the power supply. Attach the wire nut to the red wire. There should be no connection to the red wire for 120V operation.

For 240 V input power to the unit, connect the black wire to the ÒL1Ó or hot leg of the power supply. Connect the red wire to the ÒL2Ó or second hot leg of the power supply. Attach the wire nut to the white wire. There should be no connection to the white wire for 240V operation.

Heater must be electrically grounded and bonded in accordance with local codes, or, in the absence of local codes, with the latest edition of the National Electrical code, ANSI/NFPA 70.

NOTE: Input power to the heater (120/240V) should be supplied from the load (Pump) side of time clock or switch. Connecting heater to continuous power source will allow "Fail" indications (service and pressure switch) when pump is not operating.
