Installation
Top Vent Venting Runs
Example A: Acceptable Installation
If the vertical dimension from the hearth is 108" and the horizontal run to the wall
flange of the vent termination is 180" then the vent configuration is acceptable.
Example B: Acceptable Installation
If the vertical dimension from the hearth is 48" and the horizontal run to the wall
flange of the vent termination is 72"then the vent configuration is acceptable.
Example C: Unacceptable Installation
If the vertical dimension from the floor of the fireplace is 60" and the horizontal
run to the wall flange of the vent termination is 144"then the vent configuration
is
NOT acceptable

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,

B. Vertical (Through-The-Roof) 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" (11/2 feet) from a parapet wall.
