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 discharge 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 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 variable 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. Built-in
bottom pan and alternate bottom, left or
right side return air connection provision.
FEATURES AND
GENERAL OPERATION
The XV 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 pressure switch.
