Horizontal Vent Table
To use the Horizontal Vent Table (see Table 1), determine the total vertical height of the system and the number of bends
required. Locate the value on the first column and then move across to see the corresponding maximum allowable
horizontal run.
All Measurements are from the bottom of the appliance.
The Horizontal Vent Table has been established for 90 ˚ horizontal/vertical runs. Therefore, flex pipes that do not have 90 ˚
bends will not fall into this vent table relationship.
