This is the minimum vent height when using 6-5/8 inch venting. If calculating the vent height using additional
vent lengths, subtract approximately 1-1/2 inch for each pipe joint. For example, an additional 12-inch pipe
section will add approximately 10-1/2 inches overall to this dimension. Alternatively, substituting a 24-inch pipe
length for the min. 12-inch section will add 12 inches to this dimension as there is no additional pipe joint.
