FEATURES/BENEFITS

One-piece heating and cooling units with low sound levels, easy installation, low maintenance, and dependable performance. Puron® Environmentally Sound Refrigerant is Bryant’s unique refrigerant designed to help protect the environment. Puron is an HFC refrigerant which does not contain chlorine that can harm the ozone layer. The most important advantage of Puron refrigerant is that it has not been banned in future air con- ditioning systems as the traditional refrigerant R-22 has been. Puron refrigerant is in service in thousands of systems proving highly reliable, environmentally sound performance.

Perfect Heat, Perfect Humidity™ featuring Variable Speed

Blower motors provides better comfort and energy efficiency. You can expect up to 30 times better dehumidification; economi- cal constant fan for less than $50 a year, which provides improved indoor air quality and more even temperatures from room to room; and reduced indoor noise due to lower air velocity. In addition, you’ll realize improved installation flexibility with 3 different airflow choices for best overall comfort.

EASY INSTALLATION—Factory-assembled package is a com- pact, fully self-contained, combination gas heating/electric cool- ing unit that is pre-wired, pre-piped, and pre-charged for minimum installation expense.

These units are available in a variety of standard and optional heating/cooling size combinations with voltage options to meet residential and light commercial requirements. Units are light- weight and install easily on a rooftop or at ground level. The high tech composite unit base eliminates rust problems associated with ground level applications.

CONVERTIBLE DUCT CONFIGURATION—Unit is designed for easy use in either downflow or horizontal applications. Each unit is easily converted from horizontal to downflow.

EFFICIENT OPERATION

High-efficiency design offers SEER (Seasonal Energy Effi- ciency Ratios) of 13.0 and AFUE (Annual Fuel Utilization Effi- ciency) ratings as high as 81%.

Energy-saving, direct spark ignition saves gas by operating only when the room thermostat calls for heating. Standard units are furnished with natural gas controls. A low-costfield-installed kit for propane conversion is available for all units.

574B units with an “N” in the thirteenth position of model #

are dedicated Low NOx units designed for California installa- tions. These models meet the California maximum oxides of ni- trogen (NOx) emissions requirement of 40 nanograms/joule or less as shipped from the factory and MUST be installed in Cali- fornia Air Quality Management Districts where a Low NOx rule exists.

DURABLE, DEPENDABLE COMPONENTS

Compressors are designed for high efficiency. Each compres- sor is hermetically sealed against contamination to help promote longer life and dependable operation. Each compressor also has vibration isolation to provide quieter operation. All compressors have internal high pressure and overcurrent protection.

Monoport inshot burners produce precise air-to-gas mixture, which provides for clean and efficient combustion. The large monoport on the inshot (or injection type) burners seldom, if ever, requires cleaning. All gas furnace components are acces- sible in one compartment.

Turbo-tubular™ heat exchangers are constructed of alumi- nized steel for corrosion resistance and optimum heat transfer for improved efficiency. The tubular design permits hot gases to make multiple passes across the path of the supply air.

In addition, dimples located on the heat exchanger walls force the hot gases to stay in close contact with the walls, improving heat transfer.

Direct-drive variable speed (ECM) blower motor is standard

on all 574B models.

Direct-drive, PSC condenser-fan motors are designed to help reduce energy consumption and provide for cooling operation down to 55°F outdoor temperature. Motormaster® II low ambient kit is available as a field-installed accessory.
