Wall Mounted Terminations: REAR VENT
NOTE: REAR VENT APPLICATIONS MUST HAVE A 59" VERTICAL


see Figure 14 or 14a.
Fireplace must be converted to Rear Vent configuration prior to

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 14
or 14a 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 84" and the horizontal
run to the wall flange of the vent termination is 48", this would be
an acceptable installation.
Example B: (Acceptable Installation)
If the vertical dimension from the hearth is 108" and the horizontal
run to the wall flange of the vent termination is 108", this would be
an acceptable installation.
Example C: (Unacceptable Installation)
If the vertical dimension from the floor of the fireplace is 66" and
the horizontal run to the wall flange of the vent termination is 90",
this would NOT be an acceptable installation�
