Detailed Installation Instructions for
Saf-T CI Vent/Saf-T Vent Wall Penetration Assembly and Horizontal Termination
The Saf-T Vent and Saf-T CI Vent systems can be installed through any type of wall using the Saf-T CI Vent Wall
Penetration Assembly. The wall penetration requires mechanical support from the wall sufficient to support any
incidental loads on the system. If the wall is not sufficient to support the penetration assembly, then appropriate
additional framing and/or blocking is required.
Installation Procedure
The Wall Penetration Assembly is packed with the screen cover loosely slid over the inside end of the assembly.
Before beginning, remove this screen cover. Prepare an opening for the Wall Penetration Assembly in the wall.
The opening must be 5 inches larger than the nominal diameter of the Saf-T Vent system when passing through
combustible construction materials. The opening may be either round or square so long as allowance for proper
clearance to combustible material is made. When passing through solid, noncombustible construction, clearances
may be reduced if necessary. If there are not
sufficient support members to secure the Wall
Penetration Assembly or if there is a semirigid foam
insulation layer under the sheathing, the opening
must be blocked out or framed to provide support.
Position the Wall Penetration Assembly into the
enlarged hole from the outside. Secure the assembly
into the prepared opening using hollow wall anchors
or wood screws as indicated by sheathing or structural
members, sealing under the screw heads with
caulking. (Use 4 hollow wall anchors, at least 1/4
inch in diameter and of an appropriate length for the
thickness of the sheathing, if the sheathing is particle
board or other composite material. Use (4) #10 x
1-1/4" wood screws for plywood or solid wood
sheathing or solid wood members. Use suitable masonry anchors when passing through solid masonry walls.
Additional fasteners may be used if desired.) Reinstall the decorative sheathing around the Wall Penetration
Assembly. The assembly may be painted to match the exterior decor.
Proceed with the installation of Saf-T Vent or
Saf-T CI Vent sections and terminate it through
the inside of the Wall Penetration Assembly.
The assembly is constructed to allow for 2
degrees (1/4" per foot) of pitch in the vent
sections. Seal the gap between the vent and
the end plate of the termination using Dow
Corning 732, GE 106 or other silicone caulk
suitable for extended exposure to the elements.
The vent section must protrude at least 2
inches into the screened area beyond the end
plate of the Wall Penetration Assembly. Attach
the screen cover using the stainless screw(s). Align the hole in the top (solid) portion of the screen cover with the
hole in the thimble assembly and securely screw the two together. The screen cover may be easily removed for
inspection of the venting system. If local conditions require, the exterior portion may be extended using single wall
AL 29-4C stainless pipe to extend the screen cover so long as the vent section extends 2" into the screened area.
Alternately the screen cover may be removed and a Saf-T Vent screened mitre termination or other terminal Listed
for use with specific appliances may be utilized.
