General
Features
NATURAL GAS MODELS
Central Heating furnace designs are
certified to ANSI Z21.47 / CSA 2.3 for
both natural and L.P. gas. Limit setting
and rating data were established and
approved under standard rating condi-
tions 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 dis-
charge of gas fumes to the outside.
BURNERS
Multiport Inshot burners will give years of
quiet and efficient service. All models
can be converted to L.P. gas without
changing burners.
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 four 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 ex-
changer section of the cabinet is com-
pletely 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 XR 95 High Efficiency Gas Furnaces
employ a Silicon Nitride 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 pressure switch.
