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 15.
„
Once the proposed venting layout has been determined refer to
„
Figure 11 or 12 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 11.
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 11 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 138", this would be
an acceptable installation.
Example B: (Unacceptable Installation)
If the vertical dimension from the hearth is 48" and the horizontal
run to the wall flange of the vent termination is 96", this would
NOT be an acceptable installation.
Example C: (Unacceptable Installation)
If the vertical dimension from the floor of the fireplace is 72" and
the horizontal run to the wall flange of the vent termination is 120",
this would NOT be an acceptable installation.
