When a furnace is installed so that the supply ducts carry air circulated by the furnace to areas outside the space containing the furnace, the return air shall also be handled by a duct(s) sealed to the furnace casing and terminating outside the space containing the furnace.

Secure ductwork with proper fasteners for type of ductwork used. Seal supply- and return-duct connections to furnace with code approved tape or duct sealer.

Flexible connections should be used between ductwork and furnace to prevent transmission of vibration. Ductwork passing through unconditioned space should be insulated to enhance system performance. When air conditioning is used, a vapor barrier is recommended.

Maintain a 1-in. clearance from combustible materials to supply air ductwork for a distance of 36 in. horizontally from the furnace. See NFPA 90B or local code for further requirements.

For a furnace not equipped with a cooling coil, the outlet duct shall be provided with a removable access panel. This opening shall be accessible when the furnace is installed and shall be of such a size that the heat exchanger can be viewed for possible openings using light assistance or a probe can be inserted for sampling the air

Air Conditioning Contractors National Association (SMACNA) or American Society of Heating, Refrigerating and Air Conditioning Engineers (ASHRAE) or consult The Air Systems Design Guide- lines reference tables available from your local distributor. The duct system should be sized to handle the required system design CFM at the design static pressure.

stream. The cover attachment shall prevent leaks.

II. DUCTWORK ACOUSTICAL TREATMENT

Metal duct systems that do not have a 90 degree elbow and 10 ft of main duct to the first branch take-off may require internal acoustical lining. As an alternative, fibrous ductwork may be used

340MAV specifications

The Bryant 340MAV is a standout model in the Bryant lineup, designed to provide exceptional comfort, efficiency, and performance for residential heating and cooling needs. This unit offers a perfect blend of innovative technology and user-friendly features, making it an ideal choice for homeowners seeking reliability and quality.

One of the defining characteristics of the Bryant 340MAV is its impressive efficiency rating. With a SEER (Seasonal Energy Efficiency Ratio) of up to 18, this model ensures that homeowners can enjoy effective cooling during the summer months while minimizing energy consumption. Similarly, the heating efficiency is notable, with a high AFUE (Annual Fuel Utilization Efficiency) rating. This makes the 340MAV an environmentally friendly option that also promotes cost savings on energy bills.

The 340MAV incorporates advanced technologies that enhance its performance. One such technology is the variable-speed compressor, which allows the system to adjust its output based on the demands of the home. This means that the unit operates more quietly and reduces energy usage by matching the cooling or heating output required. Additionally, the two-stage heating capability provides more consistent temperatures and improved comfort throughout the space.

Operating noise is a crucial factor in residential HVAC systems, and the Bryant 340MAV is designed with this in mind. Engineered for quiet operation, the unit features a sound-dampening design, including an insulated cabinet and a specially designed compressor that minimizes noise levels.
