Jotul GF100 DV manual Vertical Venting, For a Horizontal Termination

Vertical Venting

The Jøtul GF100 DV Nordic QT is approved 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. 6 below.

Maximum Vertical should not exceed 15 ft. (4.57 m)

„In no case shall any discharge opeing on the termina- tion cap be less than 18” (457 mm) horizontally from the roof surface. See fig. 7.

„Steep roofs, nearby trees, and predominantly windy conditions can contribute to poor draft and/or promote down-draft occurances. 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.

„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. Firestops are available from all vent manufacturers. 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 enclosed. Always maintain the required 1" clearance from all sides of the vertical vent system.

„A vertical run in any horizontally-terminated system must rise a minimum of 1 ft. See fig. 12.

„Install the Exhaust Gas Restrictor in all vertically terminated or snorkel terminated vent systems. See Vent Restriction on page 8.

•ANY VENTING WITH A VERTICAL RISE MUST TERMINATE (END) WITHIN THE SHADED AREA.

•ALWAYS MAINTAIN THE PROPER CLEARANCES TO COMBUSTIBLES.
