Installation
NOTES: All dimension lengths for vertical or horizontal runs are measured
from center of the vent pipe.
Venting runs must fall within the limits set by the venting graph
(see Figure 9a).
Figure 8. Retracted Installation using a combination of solid and ex venting. Use
the vent graph to determine your allowable run, then select appropriate
components.
Figure 9. Horizontal ex installation with minimum vertical rise.
Top Vent Venting Runs
Example A: (Unacceptable Installation N.G. and L.P.)
If the vertical dimension from the hearth is 108" and the horizontal run to the wall ange
of the vent termination is 180", this would NOT be an acceptable installation.
Example B: (Acceptable Installation N.G. and L.P.)
If the vertical dimension from the hearth is 54" and the horizontal run to the wall ange
of the vent termination is 78", this would be an acceptable installation.
Example C: (Unacceptable Installation N.G. and L.P.)
If the vertical dimension from the oor of the replace is 90" and the horizontal run to
the wall ange of the vent termination is 108", this would NOT be an acceptable
installation.

B. Vertical (Through-The-Roof) 5/8 Installations
Vertical rise >12' can be reduced (on applicable models).
Vertical Terminations must be installed:
• minimum 2' (two feet) above the highest point where
vent passes through the roof.
• minimum 6' (six feet) from a mechanical air inlet
• minimum 18" (1 1/2 feet) from a parapet wall.
 Maximum vent height is:
• 32 feet above replace.
