Step 5 — Field Fabricate Ductwork

Cabinet return-air static pressure (a negative condition)

shall not exceed 0.35 in. wg (87 Pa) with economizer or

0.45 in. wg (112 Pa) without economizer.

For vertical ducted applications, secure all ducts to roof curb

and building structure. Do not connect ductwork to unit.

Fabricate supply ductwork so that the cross sectional

dimensions are equal to or greater than the unit supply

duct opening dimensions for the first 18 in. (458 mm) of

duct length from the unit basepan.

Insulate and weatherproof all external ductwork, joints,

and roof openings with counter flashing and mastic in

accordance with applicable codes.

Ducts passing through unconditioned spaces must be

insulated and covered with a vapor barrier.

If a plenum return is used on a vertical unit, the return

should be ducted through the roof deck to comply with

applicable fire codes.

A minimum clearance is not required around ductwork.

PROPERTY DAMAGE HAZARD

to roofing materials.

Membrane roofs can be cut by sharp sheet metal

edges. Be careful when placing any sheet metal parts

on such roof.
