When vent termination exits through foundations less
than 20" (508mm) below siding outcrop, the vent pipe
must flush up with the siding. A 7DVSS must also be
used.
It is always best to locate the fireplace 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 flue collar of the fireplace to the face of
the outer wall.
Horizontal plane means no vertical rise exists on
this portion of the vent assembly.
•
The maximum number of 90
°
elbows per side wall
installation is three (3).
•
For RFSDV22 & RFSDV32 the maximum
horizontal run off a minimum 12" (305mm)
vertical rise is 3' (914mm). (Fig. 10)
•
For the RFSDV42 a minimum of 24" (610mm)
vertical rise is required for a maximum
horizontal run of 3'(914mm). (Fig. 10)
•
If a 90
°
elbow is used in the horizontal vent run
(level height maintained) the maximum horizontal
vent length is reduced by 36" (914mm). (Fig. 10)
This does not apply if the 90
°
elbows are used to
increase or redirect a vertical rise. (Fig. 11)
Example: According to the chart the maximum hori-
zontal vent length is 20' (6m) and if a 90
°
elbow is
required in the horizontal vent it must be reduced to 17'
(5.2m).
(Fig. 11 Dimension A plus B must not be greater than
17' (5.2m))
•
The maximum number of 45
°
elbows permitted per
side wall installation is two (2). These elbows can be
installed in either the vertical or horizontal run. (Fig.
13)
•
For each 45
°
elbow installed in the horizontal
run, the length of the horizontal run MUST be
reduced by 18" (45cm). This does not apply if the
45
°
elbows are installed on the vertical part of
the vent system.
