3. Set the base over the opening in the floor, centering it over
the opening. Fasten the base to the floor with screws or
nails. See
Figure 37, Figure 38
and
Figure 39.
4. Drop the plenum through the opening in the base. The
flange of the plenum should rest on top of the subbase.
5. Position furnace or coil cabinet and furnace on subbase so
it aligns between the locating tabs.
This subbase for combustible floors has been designed so that
the height of the subbase raises the downflow coil off the floor to
allow easy installation of the condensate drain. See
Figure 40.
