(Figure 18 and Figure 19). 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
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
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 1/2–7 1/2" (38–191 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 20 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 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 12" (42" fireplaces) or 6" (54" fireplaces)
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 possiblity of unlocking any of the previously connected
Vent section length table
Table 17 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.
