HORIZONTAL TERMINATION

NOTE: Termination cap should pass through the wall firestop from the exterior of the building. Adjust the termination cap to its final exterior position on the building.

WARNING: Termination cap must be positioned so that arrow is pointing up.

Attach the termination cap with the four wood screws provided. Before attachment of the termination, run a bead of silicone sealant rated above 250°F on its outside edge too, so as to make a seal to the exterior wall.

NOTE: Wood screws can and should be replaced with appropriate fasteners for use on stucco, brick, concrete or other types of siding.

CAUTION: If exterior walls are finished with vinyl siding (or materials that could become discolored or warp), it is necessary to install the vinyl siding standoff SD-950.

Vinyl siding standoff SD-950 will be installed between the vent terminationandtheexteriorwall.(SeeFigure42)Thishorizontalvent termination bolts onto the flat portion of the vinyl siding standoff, so an air space will exist between the wall and the termination cap.

For installations requiring a vertical rise on the exterior of the building, 14-inch and 36-inch tall Snorkel Terminations, as shown in Figure 43a are available. Follow the same installation procedures as used for standard Horizontal Terminations. If the Snorkel Termination must be installed below grade, (i.e. basement application), proper drainage must be provided to prevent water from entering the Snorkel Termination. Refer to Figure 43b. Do not attempt to enclose the Snorkel within the wall or any other type of enclosure.
