4.Apply a bead of non-hardening mastic around the outside edge of vent cap. Position the vent cap in the center of hole on the exterior wall with the word “UP” on the vent cap facing up. Insure proper clearance of 1" to combustibles is maintained. Attach the vent cap with four wood screws supplied. Figure 19

NOTE: Replace the wood screws with appropriate fasteners for stucco, brick, concrete, or other types of siding.

For vinyl siding, stucco, or wood exterior use vinyl siding standoffs between vent cap and exterior wall. The vinyl siding standoff prevents excessive heat from melting the vinyl siding material. Bolt the vent cap to the standoff. Apply non-harden- ing mastic around outside edge of the standoff instead of the vent cap assembly. Use wood screws provided to attach the standoff. Figure 20

5.Slide fire stop over the vent pipe before connecting hori- zontal run to vent cap. Figure 21

6.Insert vent pipe into the horizontal termination. The pipe overlap should be a minimum of 1Z\v". Fasten all vent con- nections with screws provided.
