Vertical Vent Termination
The Jøtul GF 100 DV II and Jøtul GF 200 DV II are ap-
proved for vertical venting through a ceiling or to a roof
termination following these guidelines:
„ The termination should fall within the shaded area of
the grid depicted in fig.7 below.
Maximum Vertical must not exceed 15 ft. (4.57 m)
measured from the top of the stove.
„
In no case shall any discharge opening on the termi-
nation cap be less than 18” (457 mm) horizontally
from the roof surface. See fig. 8.
„ In addition the 90° elbow attached to the stove, a
vertical vent run may utilize one 90° or two 45°
elbows. Whenever possible use 45° elbows instead of
a 90° elbow as they are less restrictive to exhaust gas
and intake air flow.
„
Steep roofs, nearby trees, and predominantly windy
conditions can contribute to poor draft and/or
promote down-draft occurrences. Increasing the
height of the vent may alleviate these conditions.
„ Use approved vent manufacturer’s Wall Straps to
support an offset pipe run at three feet intervals to
avoid excessive stress on the offsets.
„
A firestop is required at every floor. Firestops are
available from all vent manufacturers. The opening
should be framed to 10" X 10" inside dimension.
„ Always maintain a minimum 1" clearance from all
sides of the vertical vent system.
„
Remove the Recirculator Plate from the back of the
Burner Skirt as shown in fig. 5. Determine which Air
Intake Restrictor plates should be used by following
the guidelines on page 9.
• ANY VENTING WITH A VERTICAL RISE MUST
TERMINATE (END) WITHIN THE SHADED AREA.
• MAXIMUM ELBOWS: TWO 90° OR ONE 90°
AND TWO 45°.
• ALWAYS MAINTAIN THE PROPER CLEARANCES
TO COMBUSTIBLES.
