ducts to building structure. Use flexible duct connectors
between unit and ducts as required. Insulate and weather
proof all external ductwork, joints and roof openings
with flashing and mastic in accordance with applicable
codes.
Ducts passing through an unconditioned space must
be insulated and covered with a vapor barrier.
A minimum clearance is not required on 50DPE014
and 50DP016 units. The 50DP020 units with electric
heat require one-in. clearance the first 24 in. of ductwork.
Outlet grilles must not lie directly helow unit discharge.
Step 4 — Make Unit Duct Connections

Ductwork openings are shown in Fig. 1 and 4. Duct
connections are shown in Fig. 5. Field-fabricated con
centric ductwork may be connected as shown in Fig. 6 and
