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 opening that may exist between the masonry
of the fireplace and the facing masonry must be
permanently sealed.
• 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.
