must comply with Venting Graph for Top vent, wall mounted terminations
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.
• Once the proposed venting layout has been determined refer to
graph 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.
Top 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 with an 'X'.
If the 'X' falls on or above the top boundary of the shaded area, the
installation is acceptable.
