In the U.S., the National Fire Protection
Association’s Code, NFPA 211, Standards for
Chimneys, Fireplaces, Vents and Solid Fuel Burning
Appliances, or similar regulations, may apply to the
installation of a solid fuel burning appliance in
your area.
In Canada, the guideline is established by the CSA
Standard, CAN/CSA-B365-M93, Installation Code
for Solid-Fuel-Burning Appliances and Equipment.
Always consult your local building inspector or
authority having jurisdiction to determine what
regulations apply in your area.

Safety Notices
• BURN SOLID WOOD FUEL ONLY
•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 AUTHORI-
TIES, INSTALLATION SPECIFICATIONS AND
REQUIREMENTS DEFER TO NFPA 211.
•DO NOT CONNECT THIS FIREPLACE TO ANY
AIR DISTRIBUTION DUCT OR SYSTEM .
•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 autho-
rized dealer regarding specific installation/
performance issues.
Installation

• Check with local building officials to determine
what permits may be required before installa-
tion.
• Notify your insurance company before installing
this fireplace.

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 installation.
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
stainless steel liner utilizing a positive connection.
•DO NOT REMOVE BRICKS OR MORTAR FROM THE
FIREPLACE OR CHIMNEY STRUCTURE. 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 combustible materials.
•CHIMNEY HEIGHT:
Minimum - 15 ft. ( 4.57 meters)
Maximum - 33 ft. (10.5 meters)
Factory-Built Fireplace Requirements
The Jøtul C450 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.
• The damper or fireplace front must be sealed to
prevent passage of room air into the the chimney
cavity.
• Circulating air chambers (i.e. in a steel fireplace
liner or metal heat circulator) may not be blocked.
• Air flow within and around the fireplace shall not
be altered by installation of the insert. The C450
Surround Panels comply with this requirement.
• Alteration of the fireplace is limited to
a) removal of the damper for liner installation
b) removal of external, non-functional trim which
must be stored within the fireplace for replace-
ment.
• Fireplace Conversion Notice PN 220508 must be
permanently attached to the back of the fireplace.
• Final approval is contingent on the authority
having local jurisdiction.

Hearth Protection Requirements
The floor area in front of fireplace insert must be
protected from live sparks and radiant heat.
• Materials: Hearth protection must be noncom-
bustible insulating board, having an R value of
2.92 (0.343 K-value) such as Kaowool® 2600 #15
or the equivalent mortared masonry material. See
Appendix A on page 18 for information how to
calculate the R-value of alternative materials.
Alternate protection must composed of materials
as specified by NFPA 211.
• Protected Area: 18” Deep x 40” Wide
A) Front - The protection must extend at least 18
inches (457 mm) forward from the glass panel in
the fireplace insert doors.
B) Sides - Protection must extend 20 inches
(508 mm) to both sides of the centerline of the
insert.
• Note that the firebox may extend out forward of
the fireplace face depending on where the
cabinet sleeve has been set to accommodate flue
connection. Always measure hearth protection
from the final, installed position of the firebox
and glass doors. See figures 9 and 10.

Chimney Connection
A positive connection must be made between the
fireplace insert and the chimney by one of the two
following approved methods.
In the U.S: See fig. 11. The insert is connected to a
listed stainless steel flexible connector that
extends beyond the chimney flue tile liner.
Alternatively, 22 ga. blue steel or greater may be
used. A sealed block-off plate must be installed
at the damper area of the existing fireplace.
In Canada: See fig. 11a. This fireplace 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.
Do not use aluminum or galvanized steel pipe for
chimney connection components - these materials
are not suitable for use with solid fuel.
Installation
1. Remove the existing damper and linkage compo-
nents 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 accommo-
date installation, use anchors or masonry nails to
attach the metal Fireplace Conversion Notice
Plate (PN 220508) to the back wall of the ma-
sonry 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.
