COMMERCIAL
SINGLE PACKAGE ROOFTOP UNITS
GAS HEATING/ELECTRIC COOLING UNITS

Standard efficiency units (580F072, 090, 120, 150 and
579F180-300) are available. Standard efficiency units
(580F036-060, 073, 091,103,121,151, and 180-300) that meet
ASHRAE 90.1-04 minimum energy efficiency requirements are
also available. High efficiency units (581B036-150 and
581A155-300) well exceed ASHRAE 90.1-04 energy efficiency
requirements and must comply with Energy Star high efficiency
requirements. Gas heating with electric cooling rooftops offer:

• Pre-painted galvanized steel cabinet for long life and quality

appearance

• Commercial strength base rails with built-in rigging capability
• Convertible design for vertical or horizontal supply/return

(036-151 and 210-300 only)

• Non-corrosive, sloped condensate drain pan, meets

ASHRAE 62 (IAQ)

• Two-inch return-air filters
• A wide assortment of factory-installed options available,

including high-static drives that provide additional perfor-
mance range

• Factory-installed optional gear driven EconoMi$er IV (vertical

return for sizes 036-151 only) for use with standard rooftop
unit controls (includes CO

2

sensor control capability)

• Factory-installed optional gear driven EconoMi$er2 (vertical

return only) for use with third party DDC controls (includes
4 to 20 mA actuator for demand control ventilation)

• Perfect Humidity™ dehumidification package (581B036-150

only)

• Hot gas reheat dehumidification package (581A181-300 only)

FEATURES/BENEFITS

Every compact one-piece unit arrives fully assembled,
charged, tested, and ready to run.

GAS HEAT MODELS

— All ignition components are contained

in the compact IGC (integrated gas controller) which is easily
accessible for servicing. The IGC control board, designed and
manufactured exclusively for Bryant rooftop units, provides
built-in diagnostic capability. An LED (light-emitting diode) sim-
plifies troubleshooting by providing visual fault notification and
system status confirmation.

The IGC also contains an exclusive anti-cycle protection for
gas heat operation. After 4 continuous cycles on the unit high-
temperature limit switch, the gas heat operation is disabled,
and an error code is issued. This feature greatly improves reli-
ability of the rooftop unit.

The IGC also contains burner control logic for accurate and
dependable gas ignition. The LED is visible without removing
the unit control box access panel. This LED fault-notification
system reduces service person troubleshooting time and mini-
mizes service costs. The IGC also maximizes heating effi-
ciency by controlling evaporator-fan on and off delays.

Tubular, dimpled gas heat exchangers optimize heat transfer
for improved efficiency. The tubular design permits hot gases
to make multiple passes across the path of the supply air. The
dimpled design creates a turbulent gas flow to maximize heat-
ing efficiency.
