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 EverlasticTM 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-InsulatedCasing—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.
