Section 3-3-1: Venting Layout: Wall mounted termination.

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 Section 3-3-3 on page 16.
„
Once the proposed venting layout has been determined refer
„
to Figure 12, 12a, or 14 to ensure the layout is acceptable.
Notes Wall Mounted Terminations: TOP VENT
All measurements for vertical or horizontal runs are measured
„
from center of the vent pipe.
Venting runs must fall within the limits set by the venting graph,
„
see Figure 12 or 13
Wall mounted Terminations
The following details are some possible configurations for Wall mounted
terminations.
The Venting Graph: P42DF*
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 13 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 120" and the horizontal
run to the wall flange of the vent termination is 144", 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.
