Section 3-3-1: Venting Layout; Top Vent, Wall Mounted Graph, L52Df; Top Vent, Wall Mounted Termination (One Elbow) - Montigo L52DF Installation & Maintenance Manual

The Venting graph: L52DF*
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 14 with an 'X'.
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 48" and the
horizontal run to the wall flange of the vent termination is 108", 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 11).

Example 1:
For our shortest venting configuration use components A and E (see
Figure 11a).

on the fireplace, for height to the center of the termination.
Important:
An inspection of the explosion relief flappers and door must be
made prior to lighting the fireplace. This will ensure the door gas-
keting material will provide an adequate seal during operation.
