To install the liner, read and follow the liner manufacturer’s in- structions 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 materi- als, 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 addi- tional 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.

WARNING
HIGH VOLTAGE !
TO AVOID THE RISK OF ELECTRICAL SHOCK, WIRING TO
THE UNIT MUST BE POLARIZED AND GROUNDED.
WARNING
HIGH VOLTAGE !
TO AVOID PERSONAL INJURY OR DEATH DUE TO
ELECTRICAL SHOCK, DISCONNECT ELECTRICAL POWER
BEFORE SERVICING OR CHANGING ANY ELECTRICAL
WIRING.
CAUTION
LABEL ALL WIRES PRIOR TO DISCONNECTION WHEN SERVICING CONTROLS. WIRING ERRORS CAN CAUSE IMPROPER AND DANGEROUS OPERATION. VERIFY PROPER OPERATION AFTER SERVICING.
WARNING
HIGH VOLTAGE !
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
NATIONAL ELECTRIC CODE.
WIRINGHARNESS
The wiring harness is an integral part of this furnace. Field alteration to comply with electrical codes should not be re- quired. Wires are color coded for identification purposes. Re- fer 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 con- ductor.
115 VOLT LINE CONNECTIONS
Before proceeding with electrical connections, ensure that the supply voltage, frequency, and phase correspond to that speci- fied 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 prop- erly sized wire, and fuse or circuit breaker. The fuse or circuit breaker must be sized in accordance with the maximum over- current protection specified on the unit rating plate. An electri- cal disconnect must be provided at the furnace location.
Connect hot, neutral, and ground wires as shown in the wiring diagram located on the unit’s blower door.
Line polarity must be observed when making field connections. Line voltage connections can be made through either the right or left side panel. The furnace is shipped configured for a right side electrical connection with the junction box located inside the burner compartment (blower compartment for downflows). To make electrical connections through the opposite side of the furnace, the junction box must be relocated to the other side of the burner (or blower) compartment prior to making electrical connections. To relocate the junction box, follow the steps shown below.
NOTE: Wire routing must not to interfere with circulator blower operation, filter removal, or routine maintenance.
