*Front clearance in alcove installation must be 24 in. (610 mm). Maintain a minimum of 24 in. (610 mm) for front service access.

**An 8” service clearance must be maintained below the unit to provide for servicing of the condensate trap unless the trap is mounted remotely.

‡ For installations on a combustible floor, do not install the furnace directly on carpeting, tile or other combustible materials other than wood flooring.

Figure 15

Suspended Installation of Horizontal Unit

This furnace may be installed in either an attic or a crawl space. Either suspend the furnace from roof rafters or floor joists, as shown in Figure 16, or install the furnace on a platform, as shown in Figure 17. A horizontal suspension kit (51W10) may be ordered from your distributor or use equivalent.

NOTE: Heavy-gauge sheet metal straps may be used to suspend the unit from roof rafters or ceiling joists. When straps are used to suspend the unit in this way, support must be provided for both the ends. The straps must not interfere with the plenum or exhaust piping installation.

Cooling coils and supply and return air plenums must be supported separately.

Typical Horizontal Application

Figure 16

NOTE: When the furnace is installed on a platform or with the horizontal suspension kit in a crawl space, it must be elevated enough to avoid water damage, accommodate drain trap and to allow the evaporator coil to drain.

Platform Installation of Horizontal Unit

1.Select location for unit keeping in mind service and other necessary clearances. See Figure 15.

2.Construct a raised wooden frame and cover frame with a plywood sheet. If unit is installed above finished space, fabricate an auxiliary drain pan to be installed under unit. Set unit in drain pan as shown in Figure 17. Leave 8 inches for service clearance below unit for condensate trap.

3.Provide a service platform in front of unit. When installing the unit in a crawl space, a proper support platform may be created using cement blocks.

4.Route auxiliary drain line so that water draining from this outlet will be easily noticed by the homeowner.

5.If necessary, run the condensate line into a condensate pump to meet drain line slope requirements. The pump must be rated for use with condensing furnaces. Protect the condensate discharge line from the pump to the outside to avoid freezing.

6.Continue with exhaust, condensate and intake piping installation according to instructions.
