In some cases, a shorter extension above the roof may be possible
with a liner than would be required with a masonry chimney.

IX HANGE VENTING ARRANGEMENTS
If the masonry chimney has more than one channel, it may be pos-
sible to vent the gas appliances into one channel and vent the solid
or liquid fuel appliance(s) into another channel(s). Do not vent an
Amana Air Command 80 inside of a metal liner with other appli-
® ®
ances vented outside the liner.
Alternatively, the homeowner may agree to discontinue use of the
fireplace (solid fuel appliance). If so, the tile liner must be cleaned
to remove creosote buildup. The fireplace opening must then be
permanently sealed.
If oil-fired appliance(s) are being replaced by gas-fired appliance(s),
the tile liner must first be cleaned to remove the fuel oil residue.
If none of the above options is practical, the Amana
80 may need to be vented vertically with a B Vent.
Under some conditions an Amana
be installed rather than an Amana
Air Command ® 90 or 95 can be vented horizontally or vertically
through PVC pipe.

IX EBUILD THE CROWN
If the chimney crown is damaged, a qualified mason must repair it
in accordance with nationally recognized building codes or stan-
dards. One such standard which may be referenced is the Stan-
dard for Chimneys, Fireplaces, Vents, and Solid Fuel Burning Ap-
pliances, ANSI/NFPA 211.

IX ELINING
Relining options include B vent and flexible liners.
If the chimney has diagonal offsets, B vent probably cannot be used.
If B vent is to be used, it must be supported adequately. Supports
(such as fire stops or thimbles) must be used to prevent the B vent
from coming into direct contact with the tile liner or chimney walls.
Direct contact would result in higher heat loss, with an increased
possibility of poor venting system performance.
It is not acceptable to vent one appliance inside the B vent and
other appliances outside. The excess space between the B vent
and the chimney walls must be covered at the top of the chimney
by a weatherproof, corrosion resistant flashing.
The B vent should then be topped with a listed vent cap. The listed
vent cap will, when installed per the manufacturer's instructions,
prevent problems due to rain, birds, or wind effects.
A B-vent installed as described in this section is considered to be
an enclosed vent system, and the sizing tables in National Fuel
Gas Code NFPA 54/ANSI Z223.1 - latest edition and in the Na-
tional Standard of Canada, CAN/CSA B149.1 and CAN/CSA B149.2
- latest editions and amendments may be used.
If a flexible liner is to be used, it must be made of the proper mate-
rials:
•
For most residential applications, an aluminum liner should
be acceptable.
•
If the combustion air supplied to the furnace will be
contaminated with compounds containing chlorine or fluorine,
a liner of AL294C stainless steel should be used. 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 Na-
tional 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 instruc-
tions 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 chim-
®
ney. (Poured insulation, either vermiculite or other materials, is no
longer recommended.) Insulation will need to be added to the flex-
ible 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 alter-
ation to comply with electrical codes should not be required. Wires
are color and number 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.
