Vertical Vent Termination
The Jøtul GF 300 DV II can be vertically vented through a
ceiling or to a roof termination with the following guide-
lines:
The termination should fall within the shaded areas

of the grids depicted in the Vent Window diagrams on
pages 10 - 11.
run should not exceed 35 ft. (10.66 m).

Minimum Vertical run must be at least 8 ft. (2.43 m).

Maximum Colinear Horizontal run is 2 ft. (61 cm).

Vent Terminus Clearance: In no case shall any dis-

charge opening on the cap be less than 18 in. (610 mm)
horizontally from the roof surface.
Steep roofs, nearby trees, and predominantly windy

conditions can contribute to poor draft and/or pro-
mote down-draft occurances. Increasing the height of
the vent may alleviate these conditions.
Use Wall Straps to support an offset pipe run at

intervals of three feet to avoid excessive stress on the
offsets.
Elbows: Four 45°, or two 90° elbows may be used.

Do not include the 45° elbow attached to the stove.
Whenever possible use 45° elbows instead of 90°
elbows as they are less restrictive to exhaust gas and
intake air flow.
A firestop is required at every floor. The opening

should be framed to 10" X 10" inside dimension.
Any venting that is exposed above the first floor,

regardless of attic space or living space, must be en-
closed. Always maintain the required 1" clearance from
all sides of the vertical vent system.
