Figure 24 - Maximum Elbow Usage
• Up to two 45° elbows may be used within the hori-
zontal run. For each 45° elbow used on the horizon-
tal plane, the maximum horizontal length must be
reduced by 18" (450 mm).
Example: Maximum horizontal length
No elbows = 10’ (3 m)
1x45° elbows = 8.5’ (2.6 m)
2x45° elbows = 7’ (2.1 m)
• A minimum of an 8' (2.5m) vertical rise is required.
• Two sets of 45°elbows offsets may be used within
the vertical sections. From 0 to a maximum of 8' (2.5
m) of vent pipe can be used between elbows.

Example: Elbow 1 = 90°
Elbow 2 = 45°
Elbow 3 = 45°
Elbow 4 = 90°
Total Angular Variation = 270°
NOTE: Horizontal sections of this vent system require
a minimum of 3" clearances to combustibles at the top
of the flue and 1" clearance at the sides and bottom
until the flue penetrates the outside wall. A minimum
1" clearance all around the flue is acceptable at this
point of penetration. If the vertical run is 7 1 /
2
ft. or
more, the clearance is 1" on sides of the horizontal
run.
Vertical sections of this vent system require a
minimum of 1" clearance to combustibles on all sides
of the pipe.
