CAN/CSA B149.2 - latest editions and amendments.

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.

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.

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.
