3.8 HORIZONTAL TERMINATION

16.5

Simple venting conﬁ guration (only one 45° and 90°

elbow)

) < (V

)

For vent conﬁ gurations requiring more than one 45° elbow and 90° elbow, the following formulas

apply:

Formula 1: H

< V

Formula 2: H

+ V

< 40 feet

Example:

= 8 FT

= V

= 8 FT

= 2.5 FT

= 2 FT

= H

+ H

= 2.5 + 2 = 4.5 FT

= .03 (one 45° elbow + two 90° elbows - 135°) = .03 (225 - 135°) = 2.7 FT

= H

+ H

= 4.5 + 2.7 = 7.2 FT

+ V

= 7.2 + 8 = 15.2 FT

Formula 1: H

< V

7.2 < 8

Formula 2: H

+ V

< 40 FT

15.2 < 40

Since both formulas are met, this vent conﬁ guration is acceptable.
