VENTING INSTALLATION
Continued
Connecting the vent pipe
Direct-vent system components are unitized concentric pipe
components featuring positive twist lock connections
(
Figure 11
and Figure 12
)
. All of the fireplaces covered in this document are
fitted with collars having locking inclined channels. The dimpled
end of the vent components fit over the fireplace/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
with the inlet of the four (4) inclined channels on the collar
(
Figure 11
).
1. Push the vent component against the collar until it fully
engages, then twist the component clockwise, running the
dimples down and along the incline channels until they seat
at the end of the channels.
NOTE:
The unitized design of the Rigid Pipe components will
engage and seal both the inner and outer vent pipe.
2. 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 twisted
(
Figure 12
).

Figure 13 - Elbow Dimensions
Vent elbows.
Vent elbows are available in 90° and 45° configurations. Refer
to
Figure 13
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 pos-
sibility of unlocking any of the previously connected vent
sections) for proper alignment
(
Figure 13
).
