ELECTRICAL WIRING

NOTE: If it is necessary to replace any of the original wiring, use 105°C wire or its equivalent, and/or 150°C wire or its equivalent, like the original wiring.

MILLIVOLT MODELS

The Millivolt models are equipped with a self-generat- ing electrical system in which the electrical current is provided by a pilot generator. No external electrical connections are required.

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

DIGITAL MODELS

NOTE:

Heaters are factory-wired for 240 VAC power supply.

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

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

SWAY BRACE

BONDING LUG (STANDARD LOCATION)

1.

Remove the two (2) screws that hold the front door

 

to the heater. Remove and set aside door for bet-

 

ter access to wiring.

2.

Remove the four (4) screws that hold down the

 

junction box to the sway brace.

3.

Remove the transformer cover located on the far

 

right by removing one (1) screw.

4.

Remove the two (2) screws that hold down the

 

transformer.

5.

Remove the one (1) screw that holds down the

 

ground wires.

6.

Disconnect P6 connector from PC board.

7.

Remove transformer from its current location and

 

relocate it on the far left side of the heater.

8.

Re-route all high-voltage wires and ground wires

9. Re-install P6 connector, ground wires (SPG),

transformer, junction box, front door, and plug right

side with the left side’s grommet plug.

NOTE: 7/8" dia. holes not utilized on jacket and control box can be used for fireman switch, auxiliary control interface or power vent (D-2) wiring.

Wiring locations

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

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 120 VAC or 240 VAC input power hookup.
