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

Filtering Methods - Non-Ducted Return Air

1.Without A/C or H/P uncased coil:

-use the fi lter supplied with the furnace; ensure that the fi lter is installed mat side down between the filter retainer and furnace top (see Figure 4).

2.With A/C or H/P uncased coil:

-use the optional coil fi lters; the fi lter sup- plied with the furnace is not used; REMOVE AND DISCARD THIS FILTER.

3.With optional coil housing:

-see coil cabinet instructions for specifi c fi ltering methods.

(see Figure 3) supplied with the duct connec- tors is recommended for use with this type of installation.

Selecting Duct Connector

Non Platinum Duct Connector

1.Determine depth of floor cavity from surface of fl oor to top of supply air duct (see Figure 5).

2.Select appropriate model from Table 4 which matches X-dimension of fl oor cavity. To maximize air delivery, remove reducer (C in Figure 5) to obtain largest open area that will fi t duct/fl oor construction.

NOTE: Duct connectors may be installed in any one of four positions.

Filtering Methods - Ducted Return Air

1.Without optional coil housing:

- install a fi lter with a minimum unrestricted medium area of 324 square inches in the duct above the coil that is accessible for monthly cleaning or replacement by hom- eowner.

2.With optional coil housing:

-install a fi lter with a minimum unrestricted medium area of 324 square inches in the duct above the coil that is accessible for monthly cleaning or replacement by hom- eowner.

Optional Duct Connectors for Downflow Systems

Duct connectors are recommended for heated air distribution in under-the-fl oor duct systems. With this system, furnaces may be installed on combustible fl ooring without a separate sub- base. Also, the furnace rear mounting plate
