Masonry Chimney Conversion - Jøtul GF 370 DV II IPI Installation And Operation Instruction Manual

Vertical Venting and Termination
The Jøtul GF 370 DV II IPI can be vertically vented
through a roof or ceiling. Follow these guidelines

Steep roofs, nearby trees, or predominantly windy
conditions, can promote poor draft or down draft
conditions. In such cases, an increase to the height
of the vent may improve performance.

If an offset or elbow is necessary in the vertical rise,
the vent pipe must be supported every three feet to avoid
excessive stress on the offsets. Use listed Wall Straps from
any of the approved vent suppliers.

A maximum of two 90° or four 45° elbows may be
used in a vertical termination. Whenever possible,
use 45° elbows instead of 90° elbows as they offer
less restriction to the flow of flue gases and intake
air.

A listed firestop is required at any floor penetration.
The opening should be framed in according to the
manufacturer's instructions.

Always maintain a minimum 1" clearance from all
sides of the vertical vent system to any combustible
material.

Minimum vertical termination height: 6 ft. of vent
pipe.
