If a 90° elbow is used in the horizontal vent run (level
height maintained) the maximum horizontal vent length
is reduced by 36” (914 mm). (Fig. 10) This does not
apply if the 90° elbows are used to increase or redirect
a vertical rise. (Fig. 11)
Since it is very important that the venting
system maintain its balance between the com-
bustion air intake and the flue gas exhaust,
certain limitations as to vent configurations
apply and must be strictly adhered to.
The vent graph showing the relationship between vertical
and horizontal side wall venting will help to determine the
various dimensions allowable.
Minimum clearance between vent pipes and combusti-
ble materials is one 1” (25mm) on top, bottom
and sides unless otherwise noted.
When the vent termination exits through founda-
tions less than 0” (508 mm) below siding outcrop,
the vent pipe must flush up with the siding.
It is always best to locate the stove in such a way that
minimizes the number of offsets and horizontal vent length
of vent pipe from the flue collar of the stove to the face of
the outer wall.
Horizontal plane means no vertical rise exists on this por-
tion of the vent assembly.
•
The maximum number of 90° elbows per side wall
installations is three (3).
•
For RFSDV4 and RFSDV34 models, the maximum
horizontal rn for a minimum 1” (305 mm) vertical rise
is 3’ (914 mm). (Fig. 9)

How to Use the Vent Graph
The vent chart should be read in conjunction with the
following vent installation instructions to determine the
relationship of the vertical and horizontal dimensions of
the vent system.
1. Determine the height of the center of the horizontal vent
pipe exiting through the outer wall. Using this dimension
on the Sidewall Vent Graph (Fig. 8), locate the point
intersecting with the slanted graph line.
. From the point of this intersection, draw a vertical line
to the bottom of the graph.
3. Select the indicated dimension, and position the stove
in accordance with same.
Example A:
If the vertical dimension from the floor of the unit is 11’
(3.4m) the horizontal run to the face of the outer wall must
not exceed 14’ (4.3 m).
Example B:
If the vertical dimension from the floor of the unit is 7’
(.14m), the horizontal run to the face of the outer wall
must not exceed 8
¹⁄₂
’ (.6 m).
