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 dimen-
sion 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 fire-

place in accordance with same.

  Example: If the vertical dimension from the floor of the 

Sidewall  Vent  Graph  showing  the  relationship  between 
vertical and horizontal dimensions for a Direct Vent flue 
system.
