Features
Natural Gas Models
Central Heating furnace designs are
certified by the American and Canadian
Gas Associations 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 pro-
gram provides total control of furnace
limit sensors, blowers, gas valve, flame
control and includes self-diagnostics for
ease of service. Also contains connec-
tion points for E.A.C./humidifier.
Air Delivery
The 4-speed, direct drive blower motor,
has sufficient airflow 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 XR 80 High Efficiency Gas Furnace
employs an adaptive 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.
