Installation Planning
Minimum Vertical Vent
Below is the minimum vent height when the elbow is placed directly on the appliance collar*. If calculating the vent
height using additional vent lengths, subtract approximately 1-1/2" for each pipe joint. For example, an additional 12"
pipe section will add approximately 10-1/2" overall to this dimension.
