THE BRYANT Plus 80x GAS FURNACE
The Plus 80x Deluxe 4--Way Multipoise Gas Furnace offers
outstanding features in an 80% AFUE furnace.
Deluxe features include: an ECM motor which enhances SEER
performance up to 1.5 points*, a third fan relay for discrete
continuous fan speed, the ability to change continuous fan speeds
from the thermostat (Fan on Plust), dehumidify mode, standard
Media Filter Cabinet, fault code storage, and more. The Plus 80x
is very quiet thanks to a new combustion design that eliminates
noise, rather than just muffle or box it in. Applications are easy
with 4--way multipoise design, through--the--furnace downflow
venting, 13 different venting options, and a door designed for easy
service access. An inner blower door is provided for tighter sealing
in sensitive applications. The 313AAV/JAV is approved for use in
Low NOx Air Quality Management Districts.
*as compared to the Air Conditioning Heating and Refrigeration
Institute’s standard coil-- only ratings when paired with selected
Bryant evaporator coils.

AND ZONING
Available in programmable and
non-programmable models,
Bryant thermostats maintain a
constant, comfortable temperature level in the home.
For the ultimate in home comfort,
Bryant’s 2, 4, and 8-zone systems
allow temperature control of individual “zones” of the home. This is
accomplished through a series of
electronic dampers and
remote room sensors.
4-zone system is shown.

HUMIDIFIER
By adding moisture to winter-dry
air, a Bryant humidifier can often
improve comfort and keep
furniture, rugs, and draperies in
better condition. Moisturizing
household air also helps to retain
normal body heat and provides
comfort at lower temperatures.

1. For common vent, vent connector sizing and vent material: United States, latest edition of the National Fuel Gas Code (NFGC),
NFPA54/ANSI Z223.1. In Canada, latest edition of the National Standards of Canada, Natural Gas and Propane Installation Code
(NSCNGPIC), CSA B149.1--00.
2. Immediately increase to 5--in. vent connector outside furnace casing when 5-- in. vent connector required, refer to Note 1.
3. Side outlet vent for upflow and downflow installations must use Type B vent immediately after exiting the furnace, except when
KGAVG0101DFG is used in downflow position.
4. Type B vent where required, refer to Note 1.
5. 4 in. single wall vent must be used inside furnace casing and the KGAVG0101DFG Downflow Vent Guard Kit.
6. Accessory Downflow Vent Guard Kit, KGAVG0101DFG required in downflow installations with bottom vent configuration.
7. Chimney Adapter Kit required for exterior masonry chimney applications. Refer to Chimney Adapter Kit, KGACA02014FC and
KGACA02015FC for sizing and complete application details.
8. Secure vent connector to furnace elbow with (2) corrosion-- resistant sheet metal screws, space approximately 180_ apart.
9. Secure all other single wall vent connector joints with (3) corrosion--resistant screws spaced approximately 120_ apart. Secure Type B
vent connectors per vent connector manufacturer’s recommendations.
*A filter is requ ired for each return ---air inlet. Airflow perfor mance included 1 ---in. (25 mm) washabl e filter media such as contained in factory ---authorized accessory filter rack. To determine airflow performance without this filter, assume an additional 0.1 in. wc available external static pressure.
* Permissible limits of the voltage range at which the u nit operates satisfactorily.
{ T ime ---delay type is recommended.
