TYPICAL INSTALLATION OFUPFLOW SYSTEMSThe following steps describe installation in-structions for an overhead supply duct systemwith a return air system that can be either overthe floor (non-ducted) or through the floor(ducted).

NOTES:• Before installing this furnace, consider all

clearances for the installation and future ser-vicing of the furnace. Refer to Table 1.

• The 2 Wire Relay Control is NOT recom-mended for upflow applications, instead, theAC/HP Relay Control (4-7 wire) should beused when converting some models to ac-cept an air conditioner. See Relay Controlinstallation instructions for further details.

Return Air and Filtering SystemsFurnaces may be installed with non-ducted orducted return air. For non-ducted systems withair conditioners or heat pumps, the followingoptional equipment is recommended: upflowstand, coil cabinet, upflow duct connector, andwall mount grille. For ducted systems with airconditioners or heat pumps, the following op-tional equipment is recommended: coil cabinetand upflow duct connector.

NOTE: Refer to the instructions supplied withany additional accessories for further installa-tion details.

Filtering Methods - Non-Ducted Return Air1. Without optional upflow stand: (see Figure 16)

-install a filter with a minimum unrestrictedmedium area of 324 square inches belowthe coil cabinet/furnace assembly that isaccessible for monthly cleaning or replace-ment by the homeowner

2. With optional upflow stand: (see Figure 15)-stand must use two filters; one is suppliedwith the stand and the other MUST beremoved from the furnace and placed in thestand - see upflow stand instructions foradditional details.

Filtering Methods - Ducted Return Air1. Install a filter with a minimum unrestricted

medium area of 324 square inches belowthe coil cabinet/furnace assembly that isaccessible for monthly cleaning or replace-ment by the homeowner
