Figure 10.b PL42DF* NG Top Vent Venting Graph for wall mounted terminations.
Figure 10.c Top Vented, wall mounted Multi-elbow installation. See Venting Graph for Top vent,
wall mounted terminations, Figure 10 or 10b.
Figure 10.d Top Vented, wall mounted Multi-elbow installation. The vent run must comply with
Venting Graph for Top vent, wall mounted terminations, Figure 10 or 10.b
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.

Top Venting Graph P42, PL42:
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
10 or 10.b with an 'X'.
If the 'X' falls on or above the top boundary of the shaded area, the
installation is acceptable.
