Installation
Figure 15.
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 102" and the horizontal
run to the wall flange of the vent termination is 108", this would be
an acceptable installation.
Example B: (Unacceptable Installation)
If the vertical dimension from the hearth is 42" and the horizontal
run to the wall flange of the vent termination is 108",
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 168",
this would nOT be an acceptable installation.

.The vent run must comply with the Venting Graph for
Rear vent,
wall mounted
terminations,
Figure 15.
An inspection of the explosion relief flappers and door
MUST
be made prior to
lighting the fireplace. A faulty seal on the door gasket and/or explosion ports will
result in products of combustion leaking into the living space and may result in
carbon monoxide poisoning.
