If your installation does not fall
within the venting graph para-
meters, please contact Montigo
for Power Venting options.
Unacceptable vent run
within shaded area.
Acceptable vent run
within non-shaded area.
The Venting Graph: L38DF*
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 108" and the horizontal
run to the wall flange of the vent termination is 180", this would be
an acceptable installation.
Example B: (Acceptable Installation)
If the vertical dimension from the hearth is 60" and the horizontal
run to the wall flange of the vent termination is 72", this would 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.

Important:
An inspection of the explosion relief flappers and door must be made
prior to lighting the fireplace. This will ensure the door gasket material
will provide an adequate seal during operation.
Section 3-3-1: VENTING LAYOUT: Wall mounted termination.
Selection of components and details of venting layout should adhere
to the following guidelines:
Vent terminations must not be recessed in walls or siding.
All through-the–wall terminations within 3’ of the fireplace must
have a Montigo Heat Shield (RHS101) installed. See
Section
3-3-3
.
All through-the-wall terminations beyond 3' of the fireplace must
have a Montigo Heat Shield (RHS8) installed. See
Section 3-3-3
.
Once the proposed venting layout has been determined refer to
Figure 14
to ensure the layout is acceptable.
Notes Wall Mounted Terminations:
Top Vent
All measurements for vertical or horizontal runs are measured
from center of the vent pipe.
Venting runs
must
fall within the limits set by the venting graph,
see
Figure 14
