6.0 Vent Guidelines

• All vent components must be installed in accordance
with the terms of their listing and manufacturer's
instructions. See the Appendix on page 39 for a
listing of approved vent manufacturers.
• The minimum height of termination cap from the
top of the unit shall be no less than 10 ft.(3.05 m),
and the maximum height shall be no more than 35 ft.
(10.67 m). See figures 6.1 - 6.2.
• Steep roofs, nearby trees, or predominantly windy
conditions can promote weak draft or occasional
downdrafts. In such cases, increasing the height of
the vent or installation of high wind termination
caps may alleviate the condition.
• HORIZONTAL RUNS are not permitted anywhere in
the venting system.
• Venting liners CANNOT be less than 3" in diameter,
nor greater than 3" in diameter.
• Any unused flue or masonry enclosure can be used
as a passageway for venting PROVIDED the flue is
relined using 3" Listed Flexible Gas Liner.
• The remaining space around the liner in a masonry or
factory-built flue CANNOT be used to vent any other
appliance.
• Listed Flexible Gas Liners may not be exposed to any
living space.
• Installation of any components not manufactured
or approved by Jøtul or failure to meet all clearance
requirements will void all warranties and could result
in property damage, bodily injury, or loss of life.
• Never modify any venting component, or use any
damaged venting product.
• THE GAS APPLIANCE AND VENT SYSTEM MUST BE
VENTED DIRECTLY TO THE OUTSIDE OF THE BUILDING,
AND NEVER ATTACHED TO A CHIMNEY SERVING A
SOLID FUEL OR GAS BURNING APPLIANCE.
• The minimum vent height above the roof or adjacent
walls is specified by building codes. A general guide
to follow is the Gas Vent Rule below.

Vent Installation Procedure
This appliance must be vented through the chimney
by a pair of 3 inch flexible aluminum liners listed for
use with gas appliances. One duct is attached to the
exhaust port on the top of the unit and will carry
the exhaust gases to the outside of the house. This
exhaust liner must run the full length of the chimney
and be directly connected to the chimney termination
cap. See figures 6.1 - 6.2.
intake port and will provide fresh air for combustion to
the unit. This liner must extend through the damper
area of the fireplace and at least into the first tile liner
of the chimney. (U.S. ONLY). This liner can also extend
the full length of the chimney and connect to the
termination cap. SEE NOTICES BELOW. See also figures
6.1-6.2.

The other 3 inch liner will be attached to the air
NOTICE
If the intake flex does not extend the full length
of the chimney and connect to the unit and the
termination cap - A NONCOMBUSTIBLE BLOCK OFF
PLATE MUST BE CONSTRUCTED AND INSTALLED ABOVE
THE UNIT BELOW THE END OF THE INTAKE DUCT
(normally at the damper area). See figure 6.1.
To avoid cross venting the insert, label the duct to
be used for the exhaust conduit at both the top and
bottom ends. This ensures that the exhaust duct will
be attached to the correct collar on the insert and on
the chimney termination kit.
CANADA NOTE: Both Intake and Exhaust ducts
must extend the full length of the chimney and be
connected to both the unit and the termination kit.
