Section 3-3-1: Venting Layout
Selection of components and details of venting layout should adhere
to the following guidelines:
 Vent terminations must not be recessed in walls or siding.
 For Heat Shield requirements see page 16.
 Once the proposed venting layout has been determined refer to
either Figure 12, 12a, 14, or 14a to ensure the layout is acceptable.
Wall Mounted Terminations: TOP VENT
 All dimension lengths for vertical or horizontal runs are measured
from center of the vent pipe.
 Venting runs must fall within the limits set by the venting graphs,
see Figure 12 or 12a.
The Venting Graph
Measure the vertical height from the fireplace hearth to the centre of
the termination and the horizontal run from the fireplace flue collar to
the wall flange of the termination. Plot on the Venting Graph Figure 12
or 12a 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 126" and the horizontal
run to the wall flange of the vent termination is 138", this would be
an acceptable installation.
Example B: (Unacceptable Installation)
If the vertical dimension from the hearth is 36" and the horizontal
run to the wall flange of the vent termination is 84", this would
NOT be an acceptable installation�
Example C: (Unacceptable Installation)
If the vertical dimension from the floor of the fireplace is 60" and
the horizontal run to the wall flange of the vent termination is 144",
this would NOT be an acceptable installation�
