The V ent Option #1 column in T able 6.2a describes a horizontal direct vent system using 3” vent pipe. From this column, we see that a CHG150 may have a vent length of up to 55ft. The first 90 elbow and the termination elbow are not considered. From T able 6.6, the equivalent length of the 3” 45 elbow is 4ft and the equivalent length of the 3” 90 degree elbow is 5.5ft. The maximum allowable run of straight pipe on this system is therefore: 55ft – 4 ft – 5.5ft = 40ft
