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", this would be an acceptable
installation.
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", this would be an acceptable

horizontal run to the wall flange of the vent termination is 144", this would
NOT be an acceptable installation.
