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 32 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.
• Vent liners may be no less than 3 inches diameter nor
greater than 3 inches diameter with the following
exception:
PROPANE NOTICE: For LP installations with vent runs
greater than 10', it is recommended that a 4" exhaust
liner be used to ensure best operating performance.
This is especially appropriate for installations in
warmer climates and intended for extended run
times. Vent pipe adapters (3" to 4") are available
from Jotul-approved venting manufacturers. When a
4" Exhaust liner is used, it is recommended that a 3"
Intake liner be run all the way to the vent terminus.
• Any unused flue or masonry enclosure can be used as
a passageway for venting provided the flue is relined
using 3" or 4" 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.
The other 3 inch liner will be attached to the air 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.
