Rear Vent
Venting Graph for
wall mounted
terminations.
Notes Wall Mounted Terminations: REAR VENT
All dimension lengths for vertical or horizontal runs are
measured from center of the vent pipe.
Venting runs
must
fall within the limits set by the venting
graphs, see Figure 15.
Fireplace must be converted to Rear Vent configuration
prior to running vent, see Figure 9 and 9a.
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 15 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
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", this would NOT be an acceptable installation.
