Safety Notices
• BURN SOLID WOOD FUEL ONLY. DO NOT BURN
OTHER FUELS.
• DO NOT USE CHEMICALS OR FLUIDS TO
START THE FIRE. DO NOT BURN GARBAGE OR
FLAMMABLE FLUIDS.
• IF THIS ROOM HEATER IS NOT PROPERLY
INSTALLED, A HOUSE FIRE MAY RESULT. TO
REDUCE THE RISK OF FIRE, FOLLOW THE
INSTALLATION INSTRUCTIONS. FAILURE TO
FOLLOW THESE INSTRUCTIONS MAY RESULT IN
PROPERTY DAMAGE, BODILY INJURY, OR LOSS
OF LIFE.
• CONTACT THE LOCAL BUILDING OR FIRE
OFFICIALS ABOUT RESTRICTIONS AND
INSTALLATION INSPECTION REQUIREMENTS IN
YOUR AREA. WHEN NOT ADDRESSED IN THIS
MANUAL, OR BY LOCAL CODE AUTHORITIES,
INSTALLATION SPECIFICATIONS AND
REQUIREMENTS DEFER TO NFPA 211 OR CSA B 365.
• DO NOT CONNECT THIS FIREPLACE TO ANY AIR
DISTRIBUTION DUCT OR SYSTEM.
• DO NOT USE GRATES OR ANDIRONS TO
ELEVATE THE FIRE. BUILD FIRE DIRECTLY ON
THE FIRECHAMBER FLOOR.
• EXTREMELY HOT WHILE IN OPERATION! KEEP
CHILDREN, CLOTHING AND FURNITURE AWAY.
CONTACT WILL CAUSE SKIN BURNS.
• NEVER OPERATE THE FIREPLACE WITH A
CRACKED OR BROKEN GLASS PANEL.
• Install smoke detectors in the living areas and
bedrooms of your home. Test them regularly
and install new batteries twice annually.
When installed in the same room as the stove,
a smoke detector should be located as far
from the stove as possible to prevent it from
sounding when adding fuel to the fire.
• Avoid creating a low pressure condition in
the room where the stove is operating. Be
aware that operation of an exhaust fan or
clothes dryer can create a low pressure area
and consequently promote flow reversal
through the stove and chimney system.The
chimney and building, however, always work
together as a system - provision of outside
air, directly or indirectly to an atmospherically
vented appliance will not guarantee proper
chimney performance. Consult your local
Jøtul authorized dealer regarding specific
installation/performance issues.

Installation
Masonry Fireplace Requirements
• The entire fireplace and chimney must be cleaned
and inspected before installation. The system
must meet local building code requirements.
• The structure and components must be free of
any defects such as cracks or broken bricks or flue
tiles. Any damage must be repaired before instal-
lation.
Any joint or gap that may exist between the
hearth extension/fireplace facing and the fire
chamber must be permanently sealed with
medium-duty refractory mortar.
• The chimney must have a clay tile liner or a stain-
less steel liner utilizing a positive connection.
• Do not remove bricks or mortar from the fire-
place or chimney. However, masonry or steel may
be removed from the smoke shelf and adjacent
damper frame area to accommodate installation
of a chimney liner, provided that their removal
will not weaken the structure of the fireplace or
chimney, and will not reduce protection for com-
bustible materials.
• Chimney Height:
Minimum - 15 ft. ( 4.57 meters)
Maximum - 33 ft. (10.5 meters)
Factory-Built Fireplace Requirements
The Jøtul C 350 Winterport may be installed into a
factory-built fireplace with the following conditions:
• The factory-built fireplace must be listed per
UL 127 or ULC S610.
• Installation must include a full height, listed
chimney liner meeting type HT requirements
(2100F) per UL 1777 (U.S.) or ULC S635 (CAN).
The liner must be securely attached to the insert
flue collar and the chimney top.
Some liner manufacturers require insulation in
order to achieve a UL 1777 or ULC-S635 listing. Check
with the manufacturer of the liner being used to
determine if insulation is required. Insulation is
recommended particularly if the chimney flue is
located in a chase outside of the building envelope.
• The top plate of the liner system MUST NOT block
the air flow between the cooling walls of the zero-
clearance fireplace air-cooled chimney system.
These cooling walls MUST remain open under all
conditions to maintain proper circulation of cooling air.
• The damper or fireplace opening must be sealed to
prevent passage of room air into the chimney cavity.
• The convection chamber and/or air circulation
louvers of the zero-clearance fireplace MUST NOT
be blocked-off. This requirement may preclude use
of the cast iron surround panels. A custom-built
surround panel system may be used provided it
does not interfere with air circulation through the
convection chamber.

Chimney Connection
This insert must be connected to a code-approved
masonry chimney or listed factory-built fireplace
chimney with a direct (positive) flue connector into the
first chimney liner section. The chimney size should not
be less than, nor more than, three times greater than
the cross-sectional area of the flue collar.
The optional Jøtul Draw-Down Adaptor Kit 156073 is
available to ease connection of the chimney liner with
the flue collar.
A positive connection must be made between the
fireplace insert and the chimney by one of the following
approved methods.
U.S. Requirement:
The insert is connected to a listed stainless steel flexible
connector that extends into the first chimney flue tile
liner. A sealed block-off plate must be installed at the
damper area of the existing fireplace. See fig. 7.
For internal chimneys, (no sides of the chimney
exposed to the outside below the roofline,) a positive
connection to the first flue tile is acceptable provided
the tile is no larger than 8” x 12”.
For external chimneys (one or more sides are exposed
to the outside below the roof line, including garages),
a positive connection to the first flue tile is acceptable
provided the tile is no larger than
8” x 8”.
A 6”, 7”, or 8” stainless steel liner, extending the full
height of the chimney, is required for all installations
where the flue tile is greater than 8” x 12” for internal
chimneys, or 9” x 8” for external chimneys.
Canada Requirement:
The insert must be installed with a continuous
chimney liner of 6” (152 mm) diameter extending
from the fireplace insert to the top of the chimney.
The chimney liner must conform to the Class 3
requirements of CAN/ULC-S635, Standard for Lining
Systems for Existing Masonry or Factory-Built
Chimneys and Vents, or CAN/ULC-S640, Standard for
Lining Systems for New Masonry Chimneys.

Installation
1. Remove the existing damper and linkage
components from the fireplace. Alternatively,
you can wire the damper plate to lock it in the
open position. Thoroughly clean the firebox and
smokeshelf area with a wire brush.
2. If the fireplace has been modified to
accommodate installation, use anchors or
masonry nails to attach the metal Fireplace
Conversion Notice Plate (PN 220508) to the back
wall of the masonry fireplace firebox where it will
be readily seen should the insert be removed.
3. Install the Flex Connection plate according to the
manufacturer’s instructions. The sealing plate may
require trimming to accommodate your specific
fireplace damper.
