„
from center of the vent pipe.
Venting runs must fall within the limits set by the venting graphs,
„
see Figure 13.

„
running vent, see Figure 8 and 8a.
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 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 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 be
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",
