Example: According to the chart the maximum
horizontal vent length is 0’ (6 m). However, if a 90°
elbow is used in the horizontal vent, maximum horizon-
tal vent length is reduced to 17’ (5. m). In Figure
9, the total of Dim. A and Dim. B must not exceed 17’
(5. m).
• The maximum number of 45° elbows permitted per
installation is six (6). These elbows can be installed in
either the vertical or horizontal run.
• For each 45° elbow installed in the horizontal run, the
length of the horizontal run MUST be reduced by 18”
(457 mm). This does not apply if the 45° elbows are
installed on the vertical part of the vent system.
• The maximum number of elbow degrees in a system is
70°. (Fig. 1)
Example:
Elbow 1 = 90°
Elbow  = 45°
Elbow 3 = 45°
Elbow 4 = 90°
Total angular variation = 70°
1 +  + 3 + 4 = 70°

STEP 1
Locate vent opening on the wall. It may be necessary to
rst position the stove and measure to obtain hole loca-
tion. Depending on whether the wall is combustible or
noncombustible, cut opening to size. (Fig. 13)
For combustible walls rst frame in opening.
Combustible Walls: (Fig. 13) Cut a 9³⁄₈”H x 9³⁄₈”W (40
x 40 mm) hole through the exterior wall and frame as
shown.
Noncombustible Walls: (Fig. 13) Hole opening must be
7¹⁄₂” (190 mm) in diameter.
