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 14
)
.
2.
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 Secure Vent
®
components will engage and seal both the inner and outer vent pipe.
3.
If desired, a #6 x 1/2” sheet metal screw can be used at the joint, but is not required as the pipe will securely
lock when twisted.
Where required, a telescopic vent section (SV4.5LA) may be used to provide the installer with an option to install
in tight and confined spaces, or where the vent run made up of fixed length pieces develops a joint in a undesirable
location, or will not build up to the required length. The telescopic vent section has an effective length of from 1-1/2”
to 7-1/2” (38 to 191 mm). The telescopic vent section is fitted 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° configurations. Refer to
Figure 16
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. Two (2) 45° elbows may be used in place of
one 90° elbow. When planning vent runs, make allowances for elbows.
NOTE:
A 90° elbow may NOT be attached directly to the appliance collar. A minimum of 6” of vent pipe must be used
between the fireplace collar and a 90° elbow. An elbow is accepatble as 1 ft of vertical rise.
1.
Rotate the elbow in a clockwise direction (to avoid the possibility of unlocking any of the previously connected
vent sections) for proper alignment
(

)
. See
Connecting the vent pipe

will assist calculating how many vent sections are needed for the planned vent configuration.
When a vent section is engaged with another section, its effective length will be 1-1/2” shorter.
