NOTE:

Furnaces with a 17-1/2 in. wide casing require an

additional procedure when locating the filter for bottom return-air

application. Field-fabricate a sheet metal filler strip 1 X 3 X 24-1/2

in. and install it along side of the filter as shown in Fig. 5. Drive

2 screws through the casing side and into the filler strip to secure

it in place. The filter is to rest on top of the filler strip when

installed.
