When vent exits through foundations less than 20" below
outcrop, the termination must be ush up with outcropped
wall above.
It is best to locate the replace in such a way that minimizes
the number of offsets and horizontal vent length.
The horizontal vent run refers to the total length of vent
pipe from the ue collar of the replace (or the top of the
Transition Elbow) to the face of the nished outside wall.
• The maximum number of 90° elbows per side wall
installation is three (3). Figure 14

Maximum Horizontal Run with No Rise
• If a 90° elbow is used in the horizontal vent run (level
height maintained) the horizontal vent length is reduced
by 36". Figure 16. This does not apply if the 90° elbows
are used to increase or redirect a vertical rise.
 According to the vent graph (Page 14) the maxi-
mum horizontal vent length in a system with a 10' vertical
rise is 17Z\x’ (5.2 m) and if a 90° elbow is required in the
horizontal vent it must be reduced to 14Z\x' (4.4 m).
In Figures 16 and 17 dimension A plus B must not be
greater than 14Z\x' (4.4 m).

• A minimum of 24" is required before a 90° elbow. If a 90°
elbow is tted directly after 24" vertical section mounted
to the top of the replace, the maximum horizontal vent
run before the termination or a vertical rise is 36” (914
mm). Figure 15
