Example: If 20 feet of (H + H

) horizontal vent run
is needed, then 4 feet minimum of (V) vertical vent
will be required.
This table shows a 1(V) to 5(H) ratio. For every 1
foot of (V) vertical, you are allowed 5 feet of (H+
H
1
) horizontal run, up to a maximum horizontal run
of 20 feet.
An elbow is acceptable as 1 foot of vertical rise except
where an elbow is the only vertical component in the
system. See Figure 38.
