V + H + H1

= 40 feet (12.2 m) Max

 

 

H = 8 feet (2.438 meters) Max.

 

 

H + H1 = 20 feet (6.096 meters) Max.

Example: If 20 feet of (H + H1) 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+ H1) horizontal run, up to a maximum horizontal run of 20 feet.

See Table 12 on Page 19 as an aid in venting component selection for a particular range of exterior wall thick- nesses.
