• 

Up to two 45° elbows may be used within the hori-
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)

• 

The minimum height of the vent above the highest 
point of penetration through the roof is 2’ (610mm).
