combustion products to a point (typically below 115°F) that any
of the approved types of pipe can also be used for venting
combustion products outside the structure. The combustion-air
and vent pipes can terminate through a side wall or through the
roof when using 1 of our approved vent termination kits.

laminated with our patented Everlastic
greater resistance to corrosion. This breakthrough in heating
technology helps extend the life of the furnace for years of
dependable performance. The heat exchanger is positioned in
the furnace to extract additional heat from the combustion
products regardless of furnace orientation.
Perfect Light™ Igniter —Bryant’s unique SiN igniter is not only
physically robust but it is also electrically robust. It is capable of
running at line voltage and does not require complex voltage
regulators as do other brands. This unique feature further
enhances the reliability of 340AAV gas furnace and continues

The model 340AAV Multipoise Condensing Furnace is specifically designed to meet the needs of the new construction
market. This high-efficiency furnace utilizes a unique 4-way
multipoise design and compact size to fit where other furnaces will not. The model 340AAV can be installed in any of 4
positions including horizontally in attics or crawlspaces, freeing space formerly used as a utility or furnace room. Except
for the 140 size, all sizes of the model 340AAV can be
installed in a manufactured (mobile) home when the optional
kit is used. With the exception of the 180 size, all sizes can be
installed with 2-pipe or 1-pipe venting. The 140 size can be
insalled only as a 2-pipe system. Sidewall or through-the-roof
venting options and the use of PVC pipe eliminate the need
for dedicated chimneys or chaseways to facilitate furnace
venting. Time-saving installation features yield a very cost
effective way to provide new home buyers with a high-efficiency and high-quality home comfort system.
heat transfer and extracts heat that conventional heat exchangers waste up the flue. The primary heat exchanger is made of
aluminized steel for corrosion resistance.
Combustion Air and Ventilation —The 340AAV advanced
design allows Schedule 40PVC, PVC-DWV, SDR-21 PVC,
SDR-26 PVC (not approved in Canada), ABS-DWV, or ABSF628 Schedule 40 pipe to bring outdoor air into the furnace for
Warranty —Limited Lifetime Warranty on the heat exchangers
for the lifetime of original owner in single family residence; 20
years in other residential and commercial applications. 5 year
Limited Warranty on entire unit.
Control Center —The printed-circuit board and all internal wir-
ing are factory installed. Convenient terminals permit quickconnection of a thermostat and air conditioning control circuits.
Connections for a humidifier and air cleaner are also provided.
4-Way Multipoise Design —Allows a model 340AAV to be
installed in an upflow, downflow, or horizontal orientation.
The model 340AAV is available in 12 heat/airflow combinations,
and when combined with the 4-way design, allows for 48 different
applications. Factory configured for upflow application, this furnace
can easily be made ready for downflow or horizontal installations.
Direct or Non-direct Venting —The 340AAV can be installed
as a 1 pipe/Non-Direct vent or 2 pipe/Direct vent furnace
except the 140 size which can be installed as 2-pipe only. This
provides added flexibility to meet diverse installation needs.
Insulated Casing —Foil-faced insulation in the heat exchanger
section cuts heat loss. The casing also has the required openings for left- or right-side connection of gas, electric, drain, and
vent connections.
Certifications —The 340AAV units are CSA (A.G.A./C.G.A.)
design certified for use with natural and propane gases, as well
as GAMA efficiency rating certified. The furnace is factoryshipped for use with natural gas. A CSA (A.G.A./C.G.A.) listed
gas conversion kit is required to convert furnace for use with
propane gas. The model 340AAV meets California Air Quality
Management District emission requirements. Except for the
140 size unit, all 340AAV models can be installed in a manufactured (mobile) home when the optional kit is used, and in
elevations up to 10,000 ft (140 size unit limitation of 7,000 ft).
Quality Registration —The 340AAV is engineered and manu-
factured under an ISO 9001 registered quality system.
