wall. This will cause a
fire hazard.

ers for stucco, brick, concrete, or other types of siding.
A vinyl siding standoff (part #950) must be used with the Simp-
son/Selkirk Horizontal Termination (part #985) on vinyl, stucco
or wood-clad exterior walls. Apply non-hardening mastic around
outside edge of the standoff instead of the vent cap assembly.
