NOTE: To avoid water damage or scalding due to valve operation, drain pipe must be connected to valve outlet and run to a safe place of discharge. Drain pipe must be the same size as the valve discharge connection throughout its entire length and must pitch downward from the valve. No shut-off valve shall be installed between the relief valve and the drain line. Valve lever should be tripped at least once a year to ensure that waterways are clear.

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.

CAUTION: Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper and dangerous operation. Verify proper operation after servicing.

DANGER - SHOCK HAZARD - Make sure electrical power to the heater is disconnected to avoid potential serious injury or damage to components.

MILLIVOLT SYSTEM

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

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 heat. The heater is supplied with a dual voltage trans- former for 120V or 240V input power hookup. Heaters are factory wired for 240V power supply.

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 ignition device is required, replace only with a 100% safety lockout device with 90 second trial for pilot ignition.
