For downflow installation on combustible flooring, an
additive base must be used as illustrated in Figure
9. Downflow combustible flooring base kit 44K15 is
available for all units.
9. Cut an opening appropriately sized for combustible
base. Base dimensions are illustrated in Figure 10.
After opening has been cut, set the additive base into
opening. Connect outlet air plenum to the additive
base. Set the unit on the additive base so flanges of
the unit drop into the base opening and seal against
the insulation strips. The unit is now locked in place.
Install return air plenum and secure with sheet metal
screws.
