INSTALLATION

I.LEVELING LEGS (IF DESIRED)

When furnace is used in upflow position with side inlet(s), leveling legs may be desired. (See Fig. 12.) Install field-supplied, corrosion-resistant 5/16-in. machine bolts and nuts.

NOTE: The maximum length of bolt should not exceed 1-1/2 in.

1.Position furnace on its back. Locate and drill a 5/16-in. diameter hole in each bottom corner of furnace. (See Fig. 12.) Holes in bottom closure panel may be used as guide locations.

2.For each hole, install nut on bolt and then install bolt and nut in hole. (Install flat washer if desired.)

3.Install another nut on other side of furnace base. (Install flat washer if desired.)

4.Adjust outside nut to provide desired height, and tighten inside nut to secure arrangement.

NOTE: Bottom closure must be used when leveling legs are used. See Bottom Closure Panel section.

→II. INSTALLATION IN UPFLOW OR DOWNFLOW APPLICATIONS

NOTE: For downflow applications, this furnace is approved for use on combustible flooring when special base (available from manufacturer) Part No. KGASB0201ALL is used. Special base in not required when this furnace is installed on manufacturer's Coil Assembly Part No. CD5 or CK5, or Coil Box Part No. KCAKC is used.

1.Determine application being installed from Table 1.

2.Construct hole in floor per dimensions specified in Table 1 and Fig. 13.

3.Construct plenum to dimensions specified in Table 1 and Fig. 13.

4.If downflow subbase (KGASB) is used, install as shown in Fig. 14.

If coil assembly CD5 or CK5 or Coil Box KCAKC is used, install as shown in Fig. 15.

NOTE: Remove furnace perforated, discharge duct flanges when they interfere with mating flanges on coil on downflow subbase. To remove furnace perforated, discharge duct flange, use wide duct pliers or duct flange tool to bend flange back and forth until it breaks off. Be careful of sharp edges. (See Fig. 16.)

WARNING: Do not bend duct flanges inward as shown in Fig. 16. This will affect airflow across heat exchangers and may cause limit cycling or premature heat exchanger failure. Remove duct flange completely or bend it inward a minimum of 210° as shown in Fig. 16.

NOTE: For 140 size unit when installed in downflow orientation, cut the white jumper wire off between terminals PL1-6 and PL1-9. Refer to Fig. 24 for location of jumper. Cut jumper close to connector and remove wire to avoid a short circuit.

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. Homeowners can enjoy a comfortable indoor climate without the disruptive racket often associated with traditional systems.

Furthermore, the Bryant 340MAV is equipped with a durable all-aluminum coil, which improves heat transfer efficiency while also being resistant to corrosion. This characteristic contributes to the longevity of the unit, ensuring that it can withstand various environmental factors without compromising performance.

Another key feature is the advanced control options that the Bryant 340MAV offers. Integration with smart thermostats allows homeowners to monitor and adjust their HVAC system remotely, ensuring optimal comfort at all times. Additionally, the system is compatible with Bryant's Perfect Air™ filtration system, enhancing indoor air quality by reducing pollutants and allergens.

In summary, the Bryant 340MAV is a high-efficiency heating and cooling solution that brings together cutting-edge technology, quiet operation, and user-friendly features. With its focus on comfort and energy savings, it stands out as a prime choice for homeowners looking to invest in a reliable HVAC system.
