Model 585B Gas/Electric Units are fully self-contained,
single-packaged combination heating/cooling horizontal-
discharge units.
These packaged units are equipped with an energy-saving
RELITE-type electric spark ignition pilot that saves gas by
operating only when the room thermostat “calls for heat­
ing.” Natural gas controls are standard. For propane opera­
tion, conversion kit P/N 301625-703 must be field-installed.
Model 585B units have two A.G.A.-certified heating input
ratings. See Table I.
These units are designed for outdoor installation either on a
rooftop or at ground level on a slab. The cooling section is
factory-charged and sealed, minimizing installation time.
Installation is easy—connect gas supply, air ducts, conden­
sate drain, high- and low-voltage wiring, and install the air
filter.
NOTE:
An optional condenser coil grille is available for field
installation. See Figure 1.
A full line of rooftop system accessories are available for
field installation. These accessories include plenums with
factory-supplied high-capacity filter and outside air intake
hood, unitized curbs, economizers (both downflow and
horizontal), barometric relief dampers, concentric diffuser
box assemblies, flexible duct packages, and high-capacity
filter racks with filters. When installing these accessories,
see Installation Instructions packaged with them.
fmportant—Read Before Installing 1. Check all local or other applicable codes for information
concerning proximity to property lines, height above
roof, obstructions, etc.
2. Make certain power supply available (volts, hertz, and
phase) corresponds to that specified on unit rating plate.
3. Check electrical supply provided by utility to be sure
that service capacity is sufficient to handle load imposed
by this unit.
4. Locate the unit where the vent cap is a minimum of 4
feet from openable windows or doors.
5. The installation must conform with local building codes
or, in the absence of local codes, with the National Fuel
Gas Code ANSI Z223.1.

I. MOVING AND SETTING UNIT IN PLACE
CAUTION:
Be sure to protect the top and sides of the unit
when rigging the unit to be lifted. See Figure 4.
Extreme caution should be used to prevent damage when
moving the unit. The unit should remain in an upright posi­
tion during all rigging and moving operations. To facilitate
lifting and moving, place the unit in an adequate rope or
cable sling.
A. Rooftop Installation
Place the unit on a level base. See Figures 8 and 9 for typical
installations. On flat roofs, be sure that the unit is at least 4
inches above the roof to prevent flooding. Consult local codes
for installation requirements. Be sure the roof will support
the additional weight. See Figure 2 for weight information.
NOTE:
See the Installation Instructions packaged with the
accessory plenum and unitized curb when these system ac­
cessories are being installed.
B. Ground Level Installation
CAUTION:
Unit must be mounted level for proper conden­
sate drainage.
Place the unit on a level concrete slab that is a minimum of
