Vertical Termination - Jøtul GF 305 DV IPI Installation And Operation Instructions Manual

Vertical Vent Termination
This appliance may be vertically vented through a ceiling
or to a roof termination using the following guidelines:
The termination should fall within the shaded areas of

the grids depicted in the Vent Matrix, fig. 6.3, page 10.
Minimum Vertical Termination is 10 ft. (3.05m).

Total run, including offsets, must not exceed 30 ft. (9.14m).

Vent Terminus Clearance: In no case shall any

discharge opening on the cap be less than 18 in. (457 mm)
horizontally from the roof surface. See fig. 6.4.
Steep roofs, nearby trees, and predominantly windy

conditions can contribute to poor draft and/or
promote draft reversal. 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.
A firestop is required at every floor. The floor opening

should be framed to 10" X 10" inside dimension.
Any venting that is exposed in living space above the

first floor must be enclosed. Always maintain the
required 1" clearance from all sides of the vertical vent
system. Insulation in attic space must be retained by
an insulation barrier.
FUNCTIONALITY NOTE:
LONG, VERTICAL VENT CONFIGURATIONS MAY
REQUIRE THE APPLIANCE BE OPERATED IN
CONTINUOUS PILOT MODE (CPI) TO ASSURE
ADEQUATE DRAFT AND PROPER PERFORMANCE.
