Figure 13c. Top Vented, wall mounted Retracted Multi-elbow installation. See
Venting Graph for Top vent, wall mounted terminations, Figure 13.
Notes Wall Mounted Terminations: SIDE VENT
All dimension lengths for vertical or horizontal runs are measured
„
from centre of the vent pipe.
Venting runs must fall within the limits set by the venting graphs,
„
see Figure 14.
Fireplace must be converted to Side 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 14 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.
