WHOLE HOUSE AIR CLEANER
The Whole House Air Cleaner uses
advanced technology to remove up to
99.98% of allergens from the filtered
air and removes particles down to .3
microns in size. Cleaning intervals of
1-3 months are typical, depending on
the home environment.
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 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
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 bottom
return air connection.
FEATURES AND GENERAL
OPERATION
The XV80i 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.

1. Be sure power agrees with equipment nameplates.
2. Low voltage (24 volt wiring) to be No. 18 A.W.G. min.
3. Grounding of equipment must comply with local codes.
4. Set thermostat heat anticipator per unit wiring diagram.
5. These leads provide 115V. power for connection of humidifier
MAX. load 1.0 amp.
6. When a single stage heating thermostat without fan switch
is used, no wiring on "G" terminal is used.
7. W1 and W2 must be jumpered together for proper operation.
Second stage heat will begin 10 minutes after first stage.
8. Set dip switches with power off per installation instructions
to set airflow and indoor fan off delays.
9. Continuous fan airflow can be increased by adding this jumper.
10. This wire is only for thermostats requiring connection to
transformer common terminal.
11. Optional humidistat is to be connected between R and BK. Factory installed jumper R
to BK on the circuit board must be cut if optional humidistat is used. The jumper must
also be cut when applying an airflow command signal to the BK input such as with the
variable speed single-zone and multi-zone system controllers. On single speed cooling
only/non-heat pump systems, jumper Y to O for proper operation of the delay profiles
and the humidistat. For two compressor or two speed systems, jumper YLo to O.
