Installation
The Venting Graph: L38DF-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 96" and the horizontal
run to the wall flange of the vent termination is 72", 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 144", 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 termi-
