IMPORTANT: Use flexible connectors between ductwork and

unit to prevent transmission of vibration. Use suitable gaskets to

ensure weather tight and airtight seal. When electric heat is

installed, use fireproof canvas (or similar heat resistant material)

connector between ductwork and unit discharge connection. If flexible duct is used, insert a sheet metal sleeve inside duct. Heat

resistant duct connector (or sheet metal sleeve) must extend 24-in.

(610 mm) from electric heater element.

3.Size ductwork for max possible air flow (See Table 1).

4.Seal, insulate, and weatherproof all external ductwork. Seal,

insulate and cover with a vapor barrier all ductwork passing

through conditioned spaces. Follow latest Sheet Metal and

Air Conditioning Contractors National Association

(SMACNA) and Air Conditioning Contractors Association

(ACCA) minimum installation standards for residential

heating and air conditioning systems.

5.Secure all ducts to building structure. Flash, weatherproof,

and vibration-isolate duct openings in wall or roof

according to good construction practices.
