A. Economizer

NOTE: If accessory power exhaust or barometric relief pack- ages are being added to the unit, install power exhaust or barometric relief before installing economizer hoods.

Economizer Hood Assembly

The economizer hood is shipped in a package secured to the outside of the unit and must be ®eld assembled. There are 2 hoods on every unit. The 580H units are side supply and side return. The return duct limits access to economizer ®lters from below. Filter tracks (mounting angle without tabs) must be installed correctly to allow access to economizer ®lters from each side.

NOTE: Before assembly of the economizer hood, check along the outer edges of the economizer assembly for any seal strip protruding past the ¯anges. Trim the excess seal strip so that it is ¯ush with the economizer assembly ¯anges.

Perform the following procedure to assemble the economizer hood:

1.a. Apply black seal strip (provided in package) to out- side top edge of hood sides. Wrap seal strip over to cover top ¯ange (4 hood sides). Make certain seal strip covers screw holes. Allow strip to overhang 1¤8 in. past end opposite mounting ¯ange. See Fig. 16.

b.Assemble hood sides, top, and cross member with gas- keted screws provided. See Fig. 17.

c.Attach 10 green speed clips (provided) to hood top.

d.Apply black seal strip to mounting ¯anges (cover holes) of hood sides. See Fig. 18.

NOTE: Each hood assembly has a slotted side that should be adjacent to the other hood when mounted to the unit.

e.Apply black seal strip to hood top mounting ¯ange. Seal strip of hood top mounting ¯ange must press against seal strip of hood side mounting ¯anges. See Fig. 19.

f.Add gray foam strip (provided) to cross members at bottom tray. See Fig. 20.

g.Place gray foam strip on inside of slotted hood side between ®lter and cross member opposite mounting end. See Fig. 21.

h.Attach gray foam strip to blockoff baffle on outer face area of ¯ange. See Fig. 22.

2.Remove the screws on each end and along top of damper assembly of unit. Remove top 2 screws on each side of ®lter panel under damper assembly. Set hood assembly in place and attach to unit using these screws.

3.Attach accessory enthalpy bracket on hood side fur- thest from control box end. Locate bracket on inside upper right hand corner using hood mounting holes. Mount outdoor-air thermistor to enthalpy bracket (if pur- chased). Attach and wire enthalpy assembly. Place quick connects on enthalpy wires.

This high-efficiency performance is particularly beneficial for those looking to lower their environmental footprint and operate a more sustainable home heating system.

The 580G uses a two-stage heating process, which allows it to operate at two levels of output. During mild weather, the furnace can run on a lower setting, providing gentle warmth while conserving energy. When temperatures drop, the system automatically ramps up to a higher output to maintain comfort. This feature not only enhances energy efficiency but also helps to eliminate temperature fluctuations, ensuring consistent warmth throughout the home.

Noise reduction technology is another remarkable aspect of the Bryant 580G. Equipped with a variable speed blower motor, this furnace operates quietly, providing a more peaceful indoor environment. The motor allows for customizable airflow, which further aids in maintaining an even temperature across different rooms and spaces.

The furnace is built with high-quality materials and features a compact design, making it a suitable option for various installation locations. Additionally, it is compatible with Bryant’s EcoNet Smart Home Management System, which enables homeowners to monitor and control their heating system remotely via a smartphone app. This integration enhances convenience and allows for timely adjustments to heating schedules, promoting energy savings.
