The Venting Graph: L52DF-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 9 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 90" and the horizontal
run to the wall flange of the vent termination is 36", 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
120", this would be an acceptable installation.
Example C:
(Unacceptable Installation)
If the vertical dimension from the floor of the fireplace is 48"
and the horizontal run to the wall flange of the vent termination
is 108", this would NOT be an acceptable installation.
Section 3-3-1: Venting Layout: Wall mounted termination.
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 9.
Wall mounted Terminations
The following details are some possible configurations for Wall
mounted terminations.

An inspection of the explosion relief flappers and door MUST be made prior to
lighting the fireplace. A faulty seal on the door gasket and/or explosion ports will
result in products of combustion leaking into the living space and may result in
carbon monoxide poisoning.
WARNING
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 9 to ensure the layout is acceptable.
