P52DF* Indoor Gas Fireplace
Notes Wall Mounted Terminations: 5"/10" Top & Rear Vent
■ All dimension lengths for vertical or horizontal runs
are measured from center of the vent pipe.
■ Venting runs must fall within the limits set by the
venting graphs, see Figure 12.
■ Fireplace must be converted to Rear Vent configuration
prior to running vent, see Figure 7 and 7a.
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 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 120" and the
horizontal run to the wall flange of the vent termination is
138", this would be an acceptable installation.
Example B: (Unacceptable 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 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.
