How to Use the Vent Graph
The Vent Graph should be read in conjunction with the
following vent installation instructions to determine the
relationship between the vertical and horizontal dimen-
sions of the vent system.
1. Determine the height of the center of the horizontal
vent pipe exiting through the outer wall. Using this
dimension on the Sidewall Vent Graph below, 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
fireplace in accorance with same.
Example: If the vertical dimension from the floor of
the fireplace is 11' (3.4 m) the horizontal run to the
face of the outer wall must not exceed 16' (4.9 m).
