Condensate Side Drain Connection; Condensate Bottom Drain Connection; Units With Hinged Panels; Remove Drain Pan - Lennox KGB024 Installation Instructions Manual

A trap must be installed between drain connection and an
open vent for proper condensate removal. See figure 5 or
6. It is sometimes acceptable to drain condensate onto
the roof or grade; however, a tee should be fitted to the
trap to direct condensate downward. The condensate line
must be vented. Check local codes concerning
condensate disposal. Refer to pages 1 and 2 for
condensate drain location.
