casing by 1 in. with the door removed.

The bottom closure pan on furnaces of widths 17 1/2 in. and larger
may be used for roll-out protection when bottom of furnace is used
for return air connection. See Fig. 17 for proper orientation of
roll-out shield.

BOTTOM RETURN AIR INLET

These furnaces are shipped with bottom closure panel installed in
