!WARNING

FIRE OR EXPLOSION HAZARD

Failure to follow this warning could result in fire, explosion, personal injury, death and/or property damage.

SConnect gas pipe to unit using a backup wrench to avoid

damaging gas controls.

SNever purge a gas line into a combustion chamber. Never test for gas leaks with an open flame. Use a commercially available soap solution made specifically for the detection of leaks to check all connections.

SUse proper length of pipe to avoid stress on gas control manifold.

SIf a flexible connector is required or allowed by authority having jurisdiction, black iron pipe shall be installed at furnace gas valve and extend a minimum of 2 in. (51 mm) outside furnace casing.

SIf codes allow a flexible connector, always use a new connector. Do not use a connector which has previously serviced another gas appliance.

8.Check for gas leaks at the field-installed and factory-installed gas lines after all piping connections have been completed. Use a commercially available soap solution made specifically for the detection of leaks (or method specified by local codes and/or regulations).

Install Electrical Connections

!WARNING

ELECTRICAL SHOCK HAZARD

Failure to follow this warning could result in personal injury or death.

The unit cabinet must have an uninterrupted, unbroken electrical ground. This ground may consist of an electrical wire connected to the unit ground screw in the control compartment, or conduit approved for electrical ground when installed in accordance with NEC, NFPA 70 National Fire Protection Association (latest edition) (in Canada, Canadian Electrical Code CSA C22.1) and local electrical codes.

HIGH-VOLTAGE CONNECTIONS

The unit must have a separate electrical service with a field-supplied, waterproof disconnect switch mounted at, or within sight from, the unit. Refer to the unit rating plate, NEC and local codes for maximum fuse/circuit breaker size and minimum circuit amps (ampacity) for wire sizing.

The field-supplied disconnect may be mounted on the unit over the high-voltage inlet hole (See Fig. 5 and 6).

NOTE: Field supplied disconnect switch box should be positioned so that it does not cover up any of the unit gas combustion supply air louvers.

Operation of unit on improper line voltage constitutes abuse and may cause unit damage that could affect warranty.

!CAUTION

UNIT COMPONENT DAMAGE HAZARD

Failure to follow this caution may result in damage to the unit being installed.

1.Make all electrical connections in accordance with NEC NFPA 70 (latest edition) and local electrical codes governing such wiring. In Canada, all electrical connections must be in accordance with CSA standard C22.1 Canadian Electrical Code Part 1 and applicable local codes. Refer to unit wiring diagram.

2.Use only copper conductor for connections between field-supplied electrical disconnect switch and unit. DO NOT USE ALUMINUM WIRE.

3.Be sure that high-voltage power to unit is within operating voltage range indicated on unit rating plate.

4.Insulate low-voltage wires for highest voltage contained within conduit when low-voltage control wires are in same conduit as high-voltage wires.

5.Do not damage internal components when drilling through any panel to mount electrical hardware, conduit, etc.

ROUTING POWER LEADS INTO UNIT

Use only copper wire between disconnect and unit. The high voltage leads should be in a conduit until they enter the duct panel; conduit termination at the duct panel must be watertight. Run the high-voltage leads through the power entry knockout on the power entry side panel. See Fig. 5 and 6 for location and size. For single-phase units, connect leads to the black and yellow wires.

CONNECTING GROUND LEAD TO GROUND SCREW

Connect the ground lead to the chassis using the ground screw on the control plate near the inducer switch (See Fig. 12).
