Common sources of chlorine and fluorine compounds

include indoor swimming pools and chlorine bleaches,

paint strippers, adhesives, paints, varnishes, sealers,

waxes (which are not yet dried) and solvents used during

construction and remodeling. Various commercial and

industrial processes may also be sources of chlorine/

fluorine compounds.

• Heavier gauge 300 and 400 series stainless steel liners

were developed for use with oil or solid fuel appliances.

They are not suitable for use with gas-fired appliances.

Flexible liners specifically intended and tested for gas

applications are listed in the UL “Gas and Oil Equipment

Directory”. (UL Standard 1777).

For sizing of flexible liners, see Note 22 and the tables in the

National Fuel Gas Code NFPA 54/ANSI Z223.1 - latest edition and

in the National Standard of Canada, CAN/CSA B149.1 and CAN/

CSA B149.2 - latest editions and amendments.

To install the liner, read and follow the liner manufacturer’s

instructions and your local codes. Excess liner length should be

pulled out of the chimney and cut off. Use caution when doing this,

as the cut edges of flexible liners may be sharp. Do not spiral

excess liner inside of the chimney. Support the liner as

recommended by the liner manufacturer.

Some manufacturers of flexible liners offer an insulation sleeve

designed to be added to the liner before it is installed in the

chimney. (Poured insulation, either vermiculite or other materials,

is no longer recommended.) Insulation will need to be added to

the flexible liner if:

• It is required by the liner manufacturer’s instructions.

• The previous liner was properly sized and installed, and

suffered from condensation damage.

• It is required by your local building codes.

Even if none of those three conditions exist which require additional

liner insulation, the installer may wish to consider it if:

• The local climate is very cold.

• The chimney is very tall.

• The vent connectors used are very long or have a large

number of elbows.

• Local experience indicates that flexible liners installed

without insulation are likely to have condensation problems.

Insulation must be selected and installed in accordance with the

liner manufacturer’s instructions.

Finally, cap the chimney and terminate the liner in accordance

with the liner manufacturer’s instructions.

VIII. ELECTRICAL CONNECTIONS

WARNING

O AVOID THE RISK OF ELECTRICAL SHOCK, WIRING TO THE UNIT MUST BE

POLARIZED AND GROUNDED.

WARNING

O AVOID INJURY, ELECTRICAL SHOCK OR DEATH, DISCONNECT ELECTRICAL

POWER BEFORE SERVICING OR CHANGING ANY ELECTRICAL WIRING.

CAUTION

ABEL ALL WIRES PRIOR TO DISCONNECTION WHEN SERVICING CONTROLS.

IRING ERRORS CAN CAUSE IMPROPER AND DANGEROUS OPERATION.

ERIFY PROPER OPERATION AFTER SERVICING.

WARNING

TO AVOID THE RISK OF INJURY, ELECTRICAL SHOCK OR DEATH, THE FURNACE

MUST BE ELECTRICALLY GROUNDED IN ACCORDANCE WITH LOCAL CODES OR,

IN THEIR ABSENCE, WITH THE LATEST EDITION OF THE

ATIONAL

LECTRIC

CODE.

WIRING HARNESS

The wiring harness is an integral part of this furnace. Field

alteration to comply with electrical codes should not be required.

Wires are color coded for identification purposes. Refer to the

wiring diagram for wire routings. If any of the original wire as

supplied with the furnace must be replaced, it must be replaced

with wiring material having a temperature rating of at least 105° C.

Any replacement wiring must be a copper conductor.

115 VOLT LINE CONNECTIONS

Before proceeding with electrical connections, ensure that the

supply voltage, frequency, and phase correspond to that specified

on the unit rating plate. Power supply to the furnace must be NEC

Class 1, and must comply with all applicable codes. The furnace

must be electrically grounded in accordance with local codes or,

in their absence, with the latest edition of The National Electric

Code, ANSI NFPA 70 and/or The Canadian Electric Code CSA

C22.1.

Use a separate fused branch electrical circuit containing properly

sized wire, and fuse or circuit breaker. The fuse or circuit breaker

must be sized in accordance with the maximum overcurrent

protection specified on the unit rating plate. An electrical disconnect

must be provided at the furnace location.

Line voltage wiring must enter into the junction box provided with

the furnace.

NOTE: Line polarity must be observed when making field

connections.

JUNCTION B OX RELOCATION

WARNING

DGES OF SHEET METAL HOLES MAY BE SHARP.

SE GLOVES AS A PRE-

CAUTION WHEN REMOVING HOLE PLUGS.

Line voltage connections can be made through either the right or

left side panel. The furnace is shipped configured for a left side

electrical connection. To make electrical connections through the

opposite side of the furnace, the junction box must be relocated to

the left side prior to making electrical connections. To relocate

the junction box, perform the following steps.

WARNING

O PREVENT PERSONAL INJURY OR DEATH DUE TO ELECTRIC SHOCK,

DISCONNECT ELECTRICAL POWER BEFORE INSTALLING OR SERVICING THIS

UNIT.
