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 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 114" and the horizontal
run to the wall flange of the vent termination is 168", 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 60", this would be
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.
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.
„ Once the proposed venting layout has been determined refer
to Figure 12, 12a, or 15 to ensure the layout is acceptable.
Notes Wall Mounted Terminations: TOP VENT
„ All measurements 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 12 or 12a.
