DOWNFLOW DUCT CONNECTORS

ATTIC INSTALLATION

All downflow installations must use a suitable duct connector approved by the furnace manufacturer for use with this furnace. The duct connec- tors are designed to be connected to the rectangular duct under the floor and sealed. Refer to the instructions supplied with the duct con- nector for proper installation. Refer to the separate accessory parts list at the end of these instructions for the approved accessory duct con- nectors.

RESIDENTIAL AND MODULAR HOME UPFLOW RETURN PLENUM CONNECTION

Return air may enter the furnace through the side(s) or bottom depend- ing on the type of application. Return air may not be connected into the rear panel of the unit.

BOTTOM RETURN AND ATTIC INSTALLATIONS

Bottom return applications normally pull return air through a base plat- form or return air plenum. Be sure the return platform structure or return air plenum is suitable to support the weight of the furnace.

The internal bottom panel must be removed for this application.

Attic installations must meet all minimum clearances to combustibles and have floor support with required service accessibility.

FIGURE 10: Typical Attic Installation

This appliance is certified for line contact when the furnace is installed in the horizontal left or right position. The line contact is only permissible between lines that are formed by the intersection of the top and two sides of the furnace and the building joists, studs or framing. This line may be in contact with combustible material. Refer to Figures 10.

When a furnace is installed in an attic or other insulated space, keep all insulating materials at least 12” (30.5 cm) away from fur- nace and burner combustion air openings.

SUSPENDED FURNACE / CRAWL SPACE INSTALLATION

The furnace can be hung from floor joists or installed on suitable blocks or pad. Blocks or pad installations shall provide adequate height to ensure the unit will not be subject to water damage. Units may also be suspended from rafters or floor joists using rods, pipe angle supports or straps. Angle supports should be placed at the supply air end and near the blower deck. Do not support at return air end of unit. All four sus- pension points must be level to ensure quite furnace operation. When suspending the furnace use a secure platform constructed of plywood or other building material secured to the floor joists. Refer to for typical crawl space installation.
