INSTALLATION OF SCREW ATTACHMENT DUCT CONNECTOR

1.Make floor cut out as shown in Figure 8.

2.Determine the depth of the floor cavity from the surface of the floor to the top of the supply air duct and select the appropriate duct connector from the chart.

3.Place locating bracket (supplied with the duct connector) to the back edge of the floor opening. See Figure 10.

4.Apply a water based duct sealant to the 1/2 in (1.3 cm) supply duct attachment flange of the duct connector.

5.Determine which of the four positions the duct connector best cen- ters over the supply duct and insert it through the floor cut-out.

6.When properly aligned with the supply duct, secure the duct con- nector to the floor with nails, flat head screws or staples.

7.Use screws as required to secure the duct connector to the supply duct.

8.Cut out the opening to the supply duct. If sealant was not used, the installer should tape the mating flanges to provide a good air seal.

NOTE: Duct sealant and tape must be classified as meeting HUD Stan- dard 3280.715, U.L. Standard 181A.

If tape is used to provide a better air seal, it should be a type approved by the applicable national or local codes.
