Vent Restrictor with Horizontal Terminations
When horizontally terminating a vent system with a vertical vent run up to 4 ft through an exterior wall, no vent
restrictor is required.
If installing more than 4 ft of vertical venting, install the restrictor (Figure 14), from inside or outside the unit, in the
inner fi replace collar. The vent restrictor is held in place by friction.

lock connections (Figures 16 and 17). All of the fi replaces covered in this document are fi tted with collars having
locking inclined channels. The dimpled end of the vent components fi t over the fi replace/vent collar to create the
positive twist lock connection.
1. Align the dimpled end over the collar, adjusting the radial alignment until the four (4) locking dimples are aligned
2. Push the vent component against the collar until it fully engages, then twist the component clockwise, running
3. If desired, a #6 x 1/2" screw can be used at the joint, but is not required as the pipe will securely lock when
Where required, a telescopic vent section (SV4.5LA) may be used to provide the installer with an option to install
in tight and confi ned spaces, or where the vent run made up of fi xed length pieces develops a joint in a undesirable
location, or will not build up to the required length. The SV4.5LA Telescopic Vent Section has an effective length of
from 1-1/2" to 7" (38 to 191 mm). The SV4.5LA is fi tted with a locking inclined channel end (identical to a normal
vent section component) and a plain end with three (3) pilot holes. Slip the plain end over the locking channel end of
a standard SV4.5 vent component the required distance and secure with three (3) screws.

Vent elbows
Vent elbows are available in 90° and 45° confi gurations. Refer to Figure 18 for the SV4.5E45 and SV4.5E90 elbow
dimensions. The elbows feature a twist section to allow them to be routed about the center axis of their initial collar
section to align with the required direction of the next vent run element.
1. Rotate the elbow in a clockwise direction (to avoid the possibility of unlocking any of the previously connected
