• 2 horizontal run of 1’ = (2 X 1’) X 1’ = 2’ of EVL
• 1 elbow 90° or "Tee" = 5’ of EVL
• 3 vertical length of 4’ = (3 X 4’) X 0.5’ = 6’ of EVL
• Total EVL = (2’ + 5’ + 6’) = 13’.
NOTE: Do not include the exterior wall termination in the EVL calculation (45° elbow
and termination).
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.
Instead, if the installation consisted of a horizontal vent coming
out at the back of the stove on a total distance of 4 feet,
followed by a tee and a 6-foot vertical rise, it would be
acceptable. The installation end should be within the allowable
configuration zone on the chart since it would have at least one
foot of vertical rise for each foot of horizontal run. Furthermore,
the total vertical rise would be at least 3-foot high.
