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. Low energy
power vent blower, to increase efficiency
and provide a positive dishcarge of gas
fumes to the outside, allows common
venting with hot water heater.
Burners
Multi-port in-shot burners will give years
of quiet and efficient service. All models
can be converted to LP gas without
changing burners.
Integrated System Control
Exclusively designed operation program
provides total control of funace limit
sensors, blowers, gas valve, flame
control and includes self-diagnostics for
ease of service.

Air Delivers
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. Built-in
bottom pan and alternate bottom, left or
right side return air connection provision.
Features and General Operation
The XE 80 High Efficiency Gas Furnaces
employ a Direct Spark 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 providing differential switch.
