Installation Guide

The Saf-T Vent CI Plus system can be installed through any type of wall using the Saf-T Vent CI Plus Wall

Termination Assembly. The wall termination requires mechanical support from the wall sufficient to support any

incidental loads on the system. If the wall is not constructed sufficiently enough to support the termination

assembly, then appropriate additional framing and/or blocking is required.

1. The Wall Termination Assembly is packed with the screen cover and end collar (Figure 1). Before

beginning, remove this screen cover. Prepare an opening for the Wall Termination Assembly in the wall.

The opening must be 7 inches larger than the Inner Vent pipe diameter. 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 Termination Assembly or if there is a semirigid foam

insulation layer under the sheathing, the opening must be blocked out or framed to provide support.

4. The vent section must protrude at least 2 inches into the screened area beyond the end plate of the

Wall Termination Assembly (Figure 4). Attach the screen cover using stainless screws. Align the hole

in the top (solid) portion of the screen cover with the top of the assembly and securely screw the two

pieces together. The screen cover may be easily removed for inspection of the venting system.

3. Proceed with the installation of Saf-T Vent CI Plus sections and terminate it through the

Wall Termination Assembly (Figure 3). Install the End Collar on the last section to close off the 1" air

space around the inner vent. Seal between the vent and the End Collar for weather conditions. 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 Assembly using silicone caulk suitable for extended exposure

to the elements.

2. Position the Wall Termination Assembly into the enlarged hole from the outside (Figure 2). Secure

the assembly using common construction methods. Seal under the screw heads with caulking.

Reinstall the decorative sheathing around the Wall Termination Assembly. The assembly may be

painted to match the exterior decor.
