HORIZONTAL VENT FIGURES / TABLES (CONTINUED) Table H H+H1 Maximum H Maximum V Minimum feet (meter) feet (meter) feet (meter) 5 (1.524) 2 (0.610) 1 (0.305) 10 (3.048) 4 (1.219) 2 (0.610) 15 (4.572) 6 (1.829) 3 (0.914) 20 (6.096) 8 (2.438) 4 (1.219) 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. 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. An elbow is acceptable as 1 foot of vertical rise except where an elbow is the only vertical component in the system. See Figure 35.
