Form No. PDS 351D.80.1
DIRECT-VENT DOWNFLOW
CONDENSING GAS FURNACE
for MANUFACTURED HOUSING
351DAS
Size 080
Series A
Utilizing the extensive resources available to Bryant, a new
standard of excellence has been achieved with the model
351DAS Downflow Furnace for manufactured (mobile) or
modular homes.
The model 351DAS is a unique downflow condensing fur-
nace with features like no other product in its class. The
351DAS builds on the many Bryant successes in the furnace
industry and establishes a new standard for high-efficiency
gas furnaces.
FEATURES
Factory Configuration
—Factory configured for downflow ap-
plications in manufactured (mobile) or modular homes.
The model 351DAS is available in 3 heat/airflow combina-
tions.
Sealed Combustion (Direct-Vent) System
—Enclosed burner
assembly isolates operating noise without the expense of
sound deadening devices. The sealed combustion (direct-
vent) system brings outdoor air directly into the combustion
chamber, reducing infiltration of cold air into the structure and
reducing heat loss.
3-Pass Primary Heat Exchangers
—This design accelerates
heat transfer and extracts heat that conventional heat ex-
changers waste up the flue. The weld-free primary heat ex-
changers are made of aluminized steel for corrosion
resistance.
Flow-Through Secondary Heat Exchangers
—Each cell is lami-
nated with our patented Everlastic
TM
polypropylene for greater
resistance to corrosion. This breakthrough in heating technology
helps extend the life of the furnace for years of trouble-free per-
formance.
Warranty
—Limited 20-year Warranty on the heat exchangers
for the original owner in single family residence. Contact your
dealer for details. Two-year limited parts and labor warranty on
entire unit.
Monoport Inshot Burners
—Produce precise air-to-gas mixture
which gives a clean burn. The large monoport on the inshot or
injection-type burners seldom, if ever, needs cleaning.
Control Center
—The printed-circuit board and all internal wiring
are factory installed. Convenient terminals permit quick-connec-
tion of a thermostat, a humidifier, an air cleaner, and air condi-
tioning control circuits.
As an added feature, the control has a built-in status indicator
and self-test feature. The status indicator flashes to indicate a
problem condition and assists the servicer in diagnosis. The self-
test feature allows for a complete check of the major compo-
nents in only seconds.
Combustion Air and Ventilation
—The 351DAS advanced design
allows Schedule 40PVC, PVC-DWV, SDR-21 PVC, SDR-26
PVC (not approved in Canada), ABS-DWV, or ABS-F628
Schedule 40 pipe to bring outdoor air into the furnace for com-
bustion. The extracted heat lowers the temperature of the com-
bustion 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.
Fully-Insulated Casing
—Foil-faced insulation in the heat ex-
changer section cuts heat loss, and insulation in the blower sec-
tion reduces noise levels. The casing also has the required
openings for left- or right-side connection of gas, electric, drain,
and vent connections.
Certifications
—The 351DAS units are A.G.A. and C.G.A. design
certified for use with natural and propane gases, as well as
GAMA efficiency rating certified. The furnace is factory-shipped
for use with natural and propane gases. (All parts necessary to
convert the gas valve for propane gas use are shipped with the
furnace.) Model 351DAS is design certified for installation in
manufactured (mobile) homes.
Quality Registration
—The 351DAS is engineered and manu-
factured under an ISO 9001 registered quality system.
