NOTE: If it is necessary to replace any of the original wiring, it must be replaced with 105° C wire or its equivalent, and /or 150° C wire or its equivalent as originally built.

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.

When installing a remote switch, do not exceed 10 feet of wiring from the heater. Use 18 gage stranded wire.

ELECTRONICINTERMITTENTIGNITIONDEVICESYS- TEM (IID)

NOTE: Heaters are factory wired for 240V power supply.

The standard field wiring connection is on the right side of the heater.

To wire the heater from the left side, follow the steps below:

Sway

Brace

Bonding Lug

(Standard Location)

ATMOSPHERIC

1.

Remove the two (2) screws that hold down the

 

junction box to the sway brace. Untie excess yellow

 

wires located behind the junction box.

2.

Move the junction box to the left side of unit and

 

attach the box to the sway brace.

3.

Secure 24V yellow wires to sway brace panel with

 

existing wire retainers.

LOW NOx

4. Connect the wires inside the junction box, either

120V or 240V depending on the field wiring.

NOTE: 7/8" Dia. holes not utilized on jacket and control box can be used for fireman switch or auxiliary control interface wiring.

NOTE: Heater must be electrically grounded and bonded. Bonding lug is provided loose with the unit. Install bonding lug on lower right or left side of jacket as necessary for bonding the unit. Mounting hole is provided on the jacket.

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

NOTE: IID Propane Units and IID Low NOx natural gas 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.
