The first 36 inches of supply air plenum and ductwork must be constructed of sheet metal as
required by NFPA 90B. The supply air plenum or duct must have a solid sheet metal bottom
directly under the unit with no openings, registers or flexible air ducts located in it. If flexible
supply air ducts are used they may be located only in the vertical walls of rectangular plenum,
a minimum of 6 inches from the solid bottom. Metal plenum of duct may be connected to the
combustible floor base, if not, it must be connected to the unit supply duct exposed to the
supply air opening from the downflow unit.
Exposing combustible (non-metal) material to the supply opening of a downflow unit can
cause a fire resulting in property damage, personal injury or death.
