The Venting Graph
Measure the vertical height from the replace hearth to the centre of the
termination and the horizontal run from the replace ue collar to the wall
ange of the termination. Plot on the Venting Graph Figure 17 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 ange of the vent termination is 138", this would be
an acceptable installation.
Example B: (Uncceptable Installation)
If the vertical dimension from the hearth is 48" and the horizontal
run to the wall ange of the vent termination is 72", this would be
would NOT be an acceptable installation.
Example C: (Unacceptable Installation)
