APPENDIX A: HORIZONTAL AND VERTICAL VENT CHART

Possible Horizontal vent length (feet)
For example, let's imagine an installation consisting of a horizontal vent
coming out at the back of the stove on a total distance of 8 feet. This
horizontal run is followed by a tee and a 6-foot vertical rise. This type of
installation is not acceptable. As you can see, the vent termination is clearly
outside the allowed configuration zone on the chart because the venting
system proposed does not have at least one foot of vertical rise for each
foot of horizontal run.
