zontal run. For each 45° elbow used on the hori-
zontal level the maximum horizontal length must be
reduced by 18" (457 mm).
Example: Maximum horizontal length:
Zero elbows = 10' (3 m)
1 x 45° elbows = 8¹⁄₂' (2.6 m)
2 x 45° elbows = 7' (2.1 m)
•
A minimum of an 8 ft. (2.43 m) vertical rise.
•
Two (2) sets of 45° elbow offsets may be used within
the vertical sections. From zero to max 8 ft. (2.43 m)
vent pipe can be used between elbows. (Fig. 30)
•
7DVCS supports offsets. (Fig. 33) This application
will require you first determine the roof pitch and use
the appropriate starter kit. See Venting Components
List, Page 22.
•
The maximum angular variation allowed in the sys-
tem is 270˚. (Fig. 31)
