Side Vent Venting Requirements
If your installation requires more than 12" of horizontal venting, some
vertical lift is required. Use the vent graph below to determine an
acceptable vent run. Unacceptable venting can affect the fireplace's
performance.
the maximum horizontal vent run is 16 feet
The Venting Graph
Measure the vertical height from the fireplace hearth to the centre of
the termination and the horizontal run from the from the fireplace flue
collar to the wall flange of the termination. Plot on the Venting Graph
(Fig. 6) with an 'X'.
If the 'X' falls on or above the top boundary of the shaded area, the
installation is acceptable.
Example A: (Acceptable Installation)
If the vertical dimension from the hearth is 82", and the hori
-
zontal run to the wall flange of the vent termination is 156", this
would be an acceptable installation.
Example B: (Acceptable Installation)
If the vertical dimension from the hearth is 72" and the horizontal
run to the wall flange of the vent termination is 36", this would be
an acceptable installation.
Example C: (Unacceptable Installation)
If the vertical dimension from the floor of the fireplace is 48" and
the horizontal run to the wall flange of the vent termination is
108",
this would NoT be an acceptable installation.

NOTES:
All dimension lengths for vertical or horizontal runs are
measured from centre of the vent pipe.
Venting runs
must
fall within the limits set by the venting
graph (see Figure 9a).

*
For venting with four 90° a restrictor may need to be used. (PEXT
5/8 Vent).
Caution:
The Installation shown in Figure 12., only 5/8 (PEXT)
Vent to be used.
