Section 3-3-1: Venting Layout: Wall Mounted Termination - Montigo L42DF ST Installation & Maintenance Manual

L42DF-ST* Indoor Gas Fireplace
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.
„
For Heat Shield requirements see Section 3-3-3.
„
Once the proposed venting layout has been determined
„
refer to Figure 12 or 13 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 12.
Wall mounted Terminations
The following details are some possible configurations for Wall
mounted terminations. See below.
The Venting Graph: L42DF-ST*
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 12 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 114" and the
horizontal run to the wall flange of the vent termination is 114",
this would be an acceptable installation.
Example B: (Acceptable Installation)
If the vertical dimension from the hearth is 78" and the horizontal
run to the wall flange of the vent termination is 54", this would
be an acceptable installation.
Example C: (Unacceptable Installation)
If the vertical dimension from the floor of the fireplace is 84"
and the horizontal run to the wall flange of the vent termination
is 138", this would NOT be an acceptable installation.
