If your installation does not fall
within the venting graph parame-
ters, please contact a local Montigo
Dealer for Power Venting options.
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 11 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 120", this would be an acceptable installation.
Example B: (Unacceptable Installation)
If the vertical dimension from the hearth is 36" and the
horizontal run to the wall flange of the vent termination
is 84", 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 144", this would not be an acceptable
installation .
