Superior Secure Vent SV4.5VFS Firestop Spacer

Superior Secure Vent SV4.5VFS Firestop Spacer

When using Secure Vent®, use SV4.5VFS firestop/spacer at ceiling joists; when using Secure Flex®, use SF4.5VF firestop/spacer. If there is living space above the ceiling level, the firestop/spacer must be installed on the bottom side of the ceiling. If attic space is above the ceiling, the firestop/spacer must be installed on the top side of the joist. Route the vent sections through the framed opening and secure the firestop/spacer with 8d nails or other appropriate fasteners at each corner.

Remember to maintain 1” (26 mm) clearance to combustibles, framing members, and attic or ceiling insulation when running vertical chimney sections. The gap between the vent pipe and a vertical firestop can be sealed with non‑combustible caulking.
