NOTE: Outdoor air or other requirements during heating operation that result in supply air temperatures below 80 degrees F or return air temperatures below 50 degrees F may cause flue gas condensate to form and is to be avoided.

DOWNFLOW APPLICATION -- CURB MOUNTING

1.The Roof Mounting Curb, (field assembled BAYCURB030,038,033,034A), or a field fabricated curb must be in place before the unit is hoisted to the roof top.

2. The Roof Mounting Curb (frame) must be installed on a flat,

level section of the roof (maximum of 1/4" per foot pitch) and provide a level mounting surface for the unit. In addition, be sure to provide sufficient height above the roof to prevent water from entering the unit.

NOTE: This unit was shipped for horizontal installation. Con-

vert to downflow per instructions:

Remove covers from the downflow supply and return air openings and place them over the horizontal supply return air openings (painted side out) and secure with sheet metal screws. See Figure 6.

3. Be sure the mounting curb spans structural members (trusses) of the roof, thereby providing sufficient support for the weight of the unit, the curb, the duct(s), and any factory or field installed accessories. See Figures 1, 7, 8, 9, 10, and 11.

8. Holes through exterior walls must be sealed in accordance with local codes.

9. All fabricated outdoor ducts should be as short as possible.

CLEARANCES

1. The recommended clearances for single-unit installations are illustrated in Figure 4. These minimum requirements are not only an important consideration when determining unit placement, but they are also essential to ensure adequate serviceability, maximum capacity, and peak operating efficiency.

2. Any reduction of the unit clearances indicated in these illustrations may result in condenser coil starvation or the recirculation of warm condenser air. Actual clearances which appear to be inadequate should be reviewed with a local engineer.

4. Be sure the hole in the structure for the ducts is large enough to accommodate the fabricated ducts and the insulation surrounding them. See Figure 4.

Note: If any internal accessories are to be added to the unit, install them at the shop if at all practical.

5. These units are design certified for outdoor installation. These units may be installed directly on wood flooring or on Class A, Class B, or Class C roof covering material. The discharge air from the condenser fans must be unrestricted for a minimum of 3 feet above the unit.

The air inlet hood in the combustion blower access panel must have adequate clearance around air openings into the combustion area. See Outline Drawing, Figure 3.
