GF 100 DV II Nordic QT GF 200 DV II Lillehammer
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
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.
