For propane operation, 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, condensate 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. Important—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. GENERAL The condensing section has been designed and tested in accordance with ARI 210. The appliance design is certified by American Gas Association for use with natural or propane gases with appropriate controls and orifices. Installation of the unit consists of the following: 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 position 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 accessories are being installed. B. Ground Level Installation CAUTION: Unit must be mounted level for proper condensate drainage. Place the unit on a level concrete slab that is a minimum of BDP Company, Division of Carrier Corp.
