General
Features
Natural Gas Models
Central heating furnace designs are
certified by the American Gas Association for both natural and L.P. gas.
Limit setting and rating data were established and approved under standard rating conditions using American
National Standards Institute standards.
Safe Operation
The Integrated System Control has
solid state devices, which continuously monitor for presence of flame,
when the system is in the heating
mode of operation. Dual solenoid combination gas valve and regulator provide 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 program provides total control of furnace
limit sensors, blowers, gas valve,
flame control and includes self-diagnostics for ease of service. Also contains connection points for E.A.C./
Humidifier.
Air Delivery
The multispeed, direct drive blower
motor, with sufficient airflow range for
most heating and cooling requirements, will switch from heating to
cooling speeds on demand from room
thermostat. The blower door safety
switch will prevent or terminate furnace 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 exchanger section of the cabinet is completely lined with foil faced fiberglass
insulation. This results in quiet and efficient 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.
