• Each terminaon is equivalent to the length of pipe of the terminaon.
• The installer must determine the number of 90-degree elbows in the vent system (two 45-degree elbows
count as one 90-degree elbow). Refer to the table and guidelines above for maximum vent length based
on the number of elbows.
