Co-linear Hearthmount Installation
The Jøtul GF 200 DV Lillehammer may be vented
through a masonry fireplace using Simpson Dura-
Vent Chimney Liner Conversion Kit 923GK. When
installed in the manner described below, this system
can improve the performance of the appliance in
cold climate situations, as well as simplify the vent
installation.
These guidelines must be followed:
1. Prior to the installation, the chimney flue must be
thoroughly cleaned and inspected by a qualified
chimney service person.
2. In a masonry chimney, a fireclay liner or listed
steel liner, must be present the entire length of
the chimney.
3. No appliance can be installed into a chimney flue
serving any other appliance of any kind.
4. The minimum length of the AIR INTAKE FLEX is 6
feet- measured off of the back of the appliance
and IT MUST EXTEND PAST THE DAMPER AREA OF
THE FIREPLACE.
5. If the intake flex does not extend the full length
of the chimney and connect to both the unit and
the termination cap, A METAL BLOCK OFF PLATE
MUST BE CONSTRUCTED AND INSTALLED ABOVE
THE UNIT PRIOR TO THE END OF THE INTAKE FLEX
AND MUST COMPLETELY SEAL THE CHIMNEY FLUE
FROM THE ROOM.
Consult with the local code authority having
jurisdiction before proceeding with this type of
installation.
Refer to the vent manufacturer’s instructions for
specific installation requirements.
