Vent Guidelines - Jøtul GI 450 DV Katahdin Installation And Operation Instructions Manual

Vent Guidelines

• All vent components must be installed in accordance
with the terms of their listing and manufacturer's
instructions.
• The minimum height of termination cap from the
top of the unit shall be no less than 10'
maximum height shall be no more than 35'
figures 2 and 4.
• 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.

• Venting liners CANNOT be less than 3" in diameter or
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 zero-clearance 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 BUILD-
ING, 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
The GI 450 DV Katahdin gas insert must be vented
through dual 3" flexible gas aluminum liners listed for
use with gas appliances.
This co-linear installation includes a pair of 3" flex
ducts that run from the insert up through the existing
chimney.
One duct is attached to the exhaust port on the
back 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 con-
nected to the chimney termination cap. See figure 2.
The other 3" liner will be attached to the intake
e in e in e in e in
port on the back of the unit and will provide fresh air
for combustion to the unit. This liner must extend a
minimum of 6' minimum o minimum o minimum o minimum o f 6' off the back of the unit and extend f 6' f 6' f 6'
through the damper area of the fireplace and into the
tile liner of the chimney. This liner can also extend the
full length of the chimney and connect to the termina-
tion cap. See figures 2 and 4.
If the intake flex does not

termination cap - A MET

(normally at the damper area). See figure 2.
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.
