L-Series DF Gas Fireplace
Part No. XG0180
f i r e f e a t u r e
Installation
Top Vent Venting Runs
For the L-Series DF
Top Vent
, there are two types of installations: A)
Through-The-Wall Installations and B) Vertical (Through-The-Roof)
Installations.
A) Through-The-Wall Installations
Before you install any venting, you must determine whether the venting
run will be acceptable. Unacceptable venting can affect the fireplace's
combustion.
The Venting Graph
Measure the vertical height from the fireplace hearth to the centre of
the termination and the horizontal run from the from the fireplace flue
collar to the wall flange of the termination. Plot on the Venting Graph
(Fig. 9a) with an 'X'.
If the 'X' falls on or above the top boundary of the shaded area, the
installation is acceptable.
L38DF
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 accept-
able installation.
Example B: (Acceptable Installation)
If the vertical dimension from the hearth is 48" 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 hori-
zontal run to the wall flange of the vent termination is 144",
this would
NOT be an acceptable installation.

Example A: (Acceptable Installation)
If the vertical dimension from the hearth is 84" 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 90" and the horizontal run to
the wall flange of the vent termination is 126", this would be an acceptable
installation.
Example C: (Unacceptable Installation)
If the vertical dimension from the floor of the fireplace is 74" and the
horizontal run to the wall flange of the vent termination is 108",
this would
NOT be an acceptable installation.

Example A: (Acceptable Installation)
If the vertical dimension from the hearth is 84" 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 72" and the
horizontal run to the wall flange of the vent termination is 84",
this would
NOT be an acceptable installation.

NOTES:
All dimension lengths for vertical or horizontal runs are
measured from centre of the vent pipe.
Venting runs
must
fall within the limits set by the venting
graph (see Figure 9a).
