How to Use the Vent Graph

The Vent Graph should be read in conjunction with the following vent installation instructions to determine the re- lationship between the vertical and horizontal dimensions of the vent system.

1.Determine the height of the center of the horizontal vent pipe exiting through the outer wall. Using this di- mension on the Sidewall Vent Graph, Figure 13, locate the point intersecting with the slanted graph line.

2.From the point of this intersection, draw a vertical line to the bottom of the graph.

3.Select the indicated dimension, and position the fire- place in accordance with same.

EXAMPLE A:

If the vertical dimension from the floor of the unit is 11’ (3.4

m)the horizontal run to the face of the outer wall must not exceed 14’ (4.3 m).

EXAMPLE B:

If the vertical dimension from the floor of the unit is 7’ (2.1 m), the horizontal run to the face of the outer wall must not exceed 8’ (2.4 m).
