Installation
If your installation does not fall

meters, please contact Montigo
for Power Venting options.
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 17.
 Fireplace must be converted to Rear Vent conguration prior to
running vent, see Figure 7 and 8.
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: (Acceptable Installation)
If the vertical dimension from the hearth is 66" and the horizontal
run to the wall ange of the vent termination is 66", this would be
an acceptable installation.
Example C: (Unacceptable Installation)
If the vertical dimension from the oor of the replace is 72" and
the horizontal run to the wall ange of the vent termination is 120",
this would NOT be an acceptable installation.
