Duct Covers; Condensate Drain - York International ZQ Series Installation Manual

Refer to Figure 11 and Figure 12 for bottom and side
air duct openings.

Duct Covers

Units are shipped with the side duct openings
covered and a covering over the bottom of the unit.
For side duct application, remove the side duct
covers and install over the bottom duct openings.
The panels removed from the side duct connections
are designed to be reused by securing each panel
to its respective bottom duct opening. But keep
in mind that the supply and return panels are
installed with the painted surface DOWN, facing the
bottom duct opening. The gasket must be removed
from the insulation side of the duct cover so it is
not directly exposed to the heating elements. The
panels are secured by sliding them into slots in the
back of the duct openings and screwing them to the
base of the unit with screws (use screws removed
from original panel location). Seals around duct
openings must be tight.
CAUTION
When fastening ductwork to side duct flanges on unit,
insert screws through duct flanges only. DO NOT
insert screws through casing. Outdoor ductwork must
be insulated and water-proofed.
