Series C
The Plus 80t Downflow Furnace achieves 80 percent Annual
Fuel Utilization Efficiency (AFUE) rating. The benefits of Perfect
Heat operation in reducing sound and improving comfort put it in
a class well ahead of the competition. The Plus 80t has the kind
of overall performance needed in today’s homes. All models are
GAMA efficiency rating certified and certified for use in California
Air Quality Management Districts.
FEATURES
EFFICIENCY — The Plus 80t Induced-Combustion Gas Fur-
nace provides the efficiency customers want with 80.0% AFUE.
HOT SURFACE IGNITION — No pilot to waste gas with this
field-proven ignition system.
ALUMINIZED HEAT EXCHANGER — The patented 4-pass
heat exchanger is made of aluminized steel and backed by a
20-year Limited Warranty.
INTELLIGENT CONTROL — The Plus 80t has an intelligent
control that monitors the operation of the furnace. This control
also has a component-test feature that enables the servicing
technician to verify operation of the control; the high and low in-
ducer; the hot surface ignitor; and high-, medium-, and low-
speed blower operation. The control features a 3-amp fuse that
protects the transformer and control. We guarantee the reliability
of the control with a 3-year Limited Warranty.
40-IN. HEIGHT — The Plus 80t cabinet height is only 40 in.
This simplifies installation in alcoves, attics, basements (ideal
for short basement), closets, and utility rooms, especially with
a taller high-efficiency cooling coil.
PREPAINTED CABINET — The Plus 80t uses prepainted sheet
metal for the cabinet. This is the same high-quality finish found
on refrigerators and other appliances today. We ensure its dura-
bility by using a galvanized steel substrate to provide superior
rust protection.
PATENTED BLOCKED VENT SAFEGUARD — Our induced-
combustion furnace has a patented blocked vent safeguard. The
safeguard switch will stop furnace operation if the vent system
becomes blocked or is not operating properly. An exclusive with
the Plus 80t furnace.
EASY INSTALLATION — The Plus 80t has many features that
make installation easier: left or right gas and electrical connec-
tions, heating and cooling blower speed selector, matching coil
sizes, accessory low-voltage connections, and many more.
QUIET OPERATION — A soft mount inducer assembly and 2-
stage slow-opening gas valve reduce sound level. The Perfect
Heat operation capability minimizes furnace and air noise for
total home comfort.

INSTALLATION
This unit is certified for downflow installation only. See Installation Manual for
important installation instructions.
This forced air furnace is equipped for
use with natural gas at altitudes 0 -
10,000 ft
(0-3,050m).
An accessory kit, supplied by the
manufacturer, shall be used to convert to
propane gas use or may be required for
some natural gas applications.
This furnace is for indoor installation in
a building constructed on site.
This furnace may be installed on
combustible flooring in alcove or closet at
minimum clearance from combustible
material.
This furnace may be used with a Type
B-1 Vent and may be vented in common
with other gas-fired appliances.
