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.
. 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' (.1
m), the horizontal run to the face of the outer wall must not
exceed 8' (.4 m).
