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 dimensions 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
accordance with same.
Example: If the vertical dimension from the fl oor of the
fi replace is 11' (3.4m) the horizontal run to the face of the
outer wall must not exceed 14' (4.3m).
Example: If the vertical dimension from the fl oor of the unit
is 7’ (2.14m), the horizontal run to the face of the outer
wall must not exceed 8
1 / 2 ' (2.6m).
