General

Features

Natural Gas Models

Central heating furnace designs are

certified by the American Gas Asso-

ciation for both natural and L.P. gas.

Limit setting and rating data were es-

tablished and approved under stan-

dard rating conditions using American

National Standards Institute stan-

dards.

Safe Operation

The Integrated System Control has

solid state devices, which continu-

ously monitor for presence of flame,

when the system is in the heating

mode of operation. Dual solenoid com-

bination gas valve and regulator pro-

vide extra safety.

Quick Heating

Durable, cycle tested, heavy gauge

aluminized steel heat exchanger

quickly transfers heat to provide warm

conditioned air to the structure.

Burners

Multi-port In-shot burners will give

years of quiet and efficient service. All

models can be converted to L.P. gas.

Integrated System Control

Exclusively designed operational pro-

gram provides total control of furnace

limit sensors, blowers, gas valve,

flame control and includes self-diag-

nostics for ease of service. Also con-

tains connection points for E.A.C./

Humidifier.

Air Delivery

The multispeed, direct drive blower

motor, with sufficient airflow range for

most heating and cooling require-

ments, will switch from heating to

cooling speeds on demand from room

thermostat. The blower door safety

switch will prevent or terminate fur-

nace operation when the blower door

is removed.

Styling

Heavy gauge steel and “wrap-around”

cabinet construction is used in the

cabinet with baked-on enamel finish

for strength and beauty. The heat ex-

changer section of the cabinet is com-

pletely lined with foil faced fiberglass

insulation. This results in quiet and ef-

ficient operation due to the excellent

acoustical and insulating qualities of

fiberglass.

Features And General Operation

The FREEDOM 80 High Efficiency

Gas Furnaces employ a Hot Surface

Ignition system, which eliminates the

waste of a constant burning pilot. The

integrated system control lights the

main burners upon a demand for heat

from the room thermostat. Complete

front service access.

a. Low energy power venter.

b. Vent proving differential switch.
