Install the U-shaped vent restrictor in any vent run with more than 4 ft of vertical

wall thicknesses.
If 20 ft of (H) horizontal vent run is needed, then 4 ft minimum of (V) vertical vent will be
required.
This table shows a 1 (V) to 5 (H) ratio. For every 1 ft of (V) vertical, you are allowed 5 ft
of (H) horizontal run, up to a maximum horizontal run of 20 ft (6.096 m).
