Installation
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 AUTHORITIES, 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 authorized dealer regarding specific installation/
performance issues.
Preparation
We strongly urge you to have your authorized Jøtul
dealer install your new Jøtul C450 Kennebec
Fireplace Insert. If you install the unit yourself, ask
your dealer to review your installation plans.
• Check with local building officials to determine
what permits may be required before installation.
• Notify your insurance company before installing
this fireplace.

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

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 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.

Installing the Firebox
1. If appropriate, use 3” flexible noncombustible
duct to connect an outside air inlet to the air
inlet collar at the back of the firebox.
2. With assistance, move the firebox into position
within the fireplace and align the insert flue
collar with the Adaptor Collar.
3. Attach the flue connector pipe. Use a 1/8” bit to
drill attachment holes into connector pipe at the
three pilot hole locations in the insert Flue Collar.
Secure the flue connector pipe using three #10 x
1/2” sheet metal screws.
4. Adjust the position of the Firebox to ensure that
the Surround Panel Hangers are flush with, or
slightly proud of, the outside face of the fireplace. If the Hangers are set back from the face,
you will be unable to engage the Surround
Hanger Clips with the holes in the Hangers.

Figure 13. Kit Contents - 155304 Blower
Optional Blower 155304
The optional two-speed blower will enhance heat
circulation around the firebox and out into the
room. The blower is controlled by a heat activated
switch (snapstat) that will ONLY function when the
control switch is in either the HI or LOW setting.
After the fire has been burning for a time, the
snapstat will react to the heat and activate the
blower, if the switch is in the HI or LOW position.
Conversely, the blower will continue to operate
until the snapstat cools as the fire wanes. The
blower will then shut off automatically.
For best performance, do not turn the switch
on until after the fire is well-established.
If the blower is not needed, place the blower
control switch in the OFF position.
THIS BLOWER MUST BE
ELECTRICALLY GROUNDED IN
ACCORDANCE WITH LOCAL CODES
OR, IN THE ABSENCE OF LOCAL
CODES, WITH THE CURRENT ANSI/
NFPA 70, NATIONAL ELECTRICAL
CODE OR CSA C22.1-CANADIAN
ELECTRICAL CODE.

which side of the ash lip extension you wish to
install the power cord and switch. The snapstat
must also be installed on that side. Use a flat
head screwdriver and pliers to pry the knockouts
from that ashlip support. Work from the inside,
to avoid marring the outside surface. Insert the
Power Switch in the upper hole. Insert the Power
Cord Receptacle into the lower hole. See fig. 14.
4. Attach the Blower: Use a 7 mm wrench or long
socket to attach the Blower to the Extension

Operation
Read the following section carefully before building
a fire in your Jøtul C450 Kennebec Fireplace Insert.
Fuel
This stove is designed to burn natural wood ONLY.
Wood that has been air-dried for a period of 6 to 14
months will provide the cleanest most efficient
heat. Frequent use of green or inadequately sea-
soned wood is conducive to creosote accumulation
and generally poor performance.
DO NOT BURN...
•Coal •Treated or painted wood
•Garbage •Chemical Chimney cleaners
•Cardboard •Colored paper
•Solvents •Any synthetic fuel or logs
The burning of any of these materials can result in
the release of toxic fumes. NEVER USE GASOLINE,
GASOLINE-TYPE LANTERN FUEL, KEROSENE, CHARCOAL LIGHTER FLUID, OR SIMILAR LIQUIDS TO START
OR “FRESHEN-UP” THE FIRE. Always keep such
liquids away from the heater at all times.

FOR PROPER AIR FLOW WITHIN THE
STOVE.
Air Control
A single lever regulates the Primary Air flow that
controls the intensity of the fire and consequent
heat output and burn time. This lever is located on
the front of the stove directly above the ashlip.
When first starting or reviving the fire, the
control lever should be set at the far right position
to allow the maximum amount of air into the stove.
See fig. 21. After the fire is well-established, the
lever should be set at position to moderate incoming air to maintain the desired long term heat
output and/or burn time.
In general, the more air made available to the
fuel will result in the hottest fire intensity and the
fastest fuel consumption. Alternatively, the less air
made available to the firebox will result in low heat
output and slow fuel consumption.

Starting and Maintaining a Fire
Burn only solid wood directly on the bottom grate
of the stove, do not elevate the fire in any way.
1. Set the Air Control Lever in the full open position.
2. Crumple several sheets of newspaper directly
on the grate.
2. Place several pieces of small dry kindling (approx.
1” in diameter) on top of the newspaper, with
two to three small logs (approx. 2” to 3” in
diameter) on top.
3. Light the fire and close the door. Gradually build
the fire by adding larger and larger logs as the
fire develops a bed of coals.
4. When you have added the final logs, adjust the
Air Control Lever to provide the desired fire
intensity.
Experiment with a variety of air control settings
to determine the best one for your individual
circumstances. Remember that fuel characteristics,
chimney system condition, building design, and
weather conditions all affect the performance of
your fireplace insert. In time, you will discover how
these elements combine and how you can work
with them to achieve satisfactory performance.
NEVER OVERFIRE THE STOVE. IF ANY PART OF
THE STOVE OR CHIMNEY GLOWS, YOU ARE
OVERFIRING. A HOUSE FIRE OR SERIOUS
DAMAGE TO THE STOVE OR CHIMNEY COULD
RESULT. IF THIS CONDITION OCCURS,
IMMEDIATELY CLOSE THE AIR CONTROL.
Adding Fuel to the Fire
When reloading the stove while a bed of hot
embers still exists, follow this reloading procedure:
• Always wear stove gloves when tending to the
fire.
• Push the Air Control Lever to the full open
position (far right).
• Wait a few seconds before opening the door.
This allows the renewed air circulation to clear
unburned gases from the firebox.
• Use a stove tool or poker to distribute the hot
embers equally around the firebox.
• Load the fuel, usually with smaller logs first.
• Close the doors and secure the latch.
• Wait 5 – 10 minutes for the fire to re-establish
before adjusting the Air Control Lever for the
desired heat output. If a thick bed of live coals is
present, you may be able to add fuel and immediately set the air control without waiting for the
fire to be re-established.
Creosote Formation
The Jøtul C450 Kennebec is designed to burn wood
cleanly and efficiently when operated as described
in this manual. However, when wood is burned
slowly and at low temperatures, tar and other
organic vapors are produced which condense on the
relatively cooler chimney flue surfaces to form
creosote. Failure to keep the chimney system free of
creosote build up could result in a chimney fire.
The creosote that accumulates in the chimney
is highly flammable and is the fuel of chimney fires.
To prevent chimney fires, it is important to have the
chimney flue and connector pipe inspected at least
twice annually and cleaned whenever accumulation
of 1/4” or more is evident. A qualified chimney
sweep or other authorized service person can
provide this service.
It is also important to remember that chimney
size, temperature and height all affect draft which
in turn affects the formation of creosote. An
exterior chimney, whether masonry or prefabricated
steel, will be exposed to cold outside temperatures,
and consequently, will be more prone to creosote
accumulation than an interior flue.
A chimney flue located within the home interior
will benefit from the insulating characteristics of
the building itself. Consequently, the flue system
will be less conducive to condensation of unburned
gases and minimal creosote accumulation will
result.
As a general rule, try to avoid burning the insert
at the lowest air control settings. Although a low
setting will prolong burn time, it may also result in
incomplete combustion. In reducing the fire intensity, draft is weakened and the chimney flue cools.
This, together with the increase in unburned gases,
leads to rapid creosote accumulation.
Break-in Period Ventilation
It is normal for a new stove to emit odor and
possibly smoke during the first few fires. This is
characteristic of the burn-off of residues from the
manufacturing process and the curing of painted
surfaces. Open a window near the fireplace insert
to provide plenty of fresh air to the room during this
“seasoning” period.
17
Maintenance
Ash Removal
Always wear stove gloves when handling ashes.
Ash removal will be required periodically depending
on how frequently the stove is used. Use a steel ash
shovel and metal container with a tight-fitting lid.
NEVER USE A PAPER OR PLASTIC BAG AS AN ASH
RECEPTACLE.
The container of ashes should be placed on a
noncombustible floor or on the ground, well away
from all combustible materials, pending final
disposal. If the ashes are disposed of by burial in soil
or otherwise dispersed, they should be kept in the
closed container until all coals and cinders have
thoroughly cooled.
Glass Care
Cleaning
Occasionally it will be necessary to clean the carbon
deposits and fly ash off of the glass. If deposits are
allowed to remain on the glass for an extended
period of time, the glass may become etched and
cloudy.
Creosote deposits should burn off during the next
hot fire.
1. The Glass must be COMPLETELY COOL.
2. Only use a cleaner that is specifically designed
for this purpose. DO NOT USE ABRASIVE CLEAN-
ING AGENTS. The use of abrasives will damage
the glass, leaving a frosted surface. Crumpled
newspaper is an especially good cleaning material.
3. Rinse and dry glass completely before lighting a
fire.
Glass Removal
Always operate the doors slowly and cautiously to
avoid cracking or breaking the glass. Never use the
door to push wood into the firebox. If the glass
becomes cracked or broken follow the replacement
procedure below.
IMPORT ANT:
REPLACE GLASS ONLY WITH JØTUL
CERAMIC GLASS PART #220356
SPECIFICALL Y DESIGNED FOR THE
JØTUL C450 KENNEBEC FIREPLACE
INSERT. DO NOT USE SUBSTITUTES.
REPLACEMENT GLASS PANELS CAN
BE ORDERED THROUGH Y OUR JØTUL

NEVER OPERA TE THE STOVE WITH A
CRACKED OR BROKEN GLASS PANEL.
1. Remove the door from the stove and place on a
flat surface.
2. Carefully remove all of the glass clips from the
inside of the door. See fig. 22.
3. Gently remove all pieces of the glass panel and
gasketing.
4. Remove all remaining debris from the glass area
using a wire brush.
5. Apply a small bead of gasket/stove cement and
the new gasket. Do not overlap the ends of the
gasket rope.
6. Center the new glass panel over the gasket and
reinstall the glass clips.
7. It may be necessary to retighten the glass clips
after the stove has burned and the gasketing has
been seated.

General Maintenance
Regular maintenance will assure proper performance and prolong the life of your Jøtul C450
Kennebec. The following procedures do not take
long and are generally inexpensive. When done
consistently, they will help increase the life of your
fireplace insert and assure satisfactory performance.
• Thoroughly clean the insert. Enamel surfaces
should be cleaned with soap and water.
• Empty firebox of all soot and ashes. Never use a
household vacuum cleaner to remove ashes.
Only a shop vac with a metal container is
acceptable and only when you are certain the
ashes are cold.
• Inspect the firebox using a utility light inside
and out for cracks or leaks. Replace all cracked
bricks and repair leaks with furnace cement.
Removing the Insert for Cleaning
1. Lift the Ashlip from the Ashlip Extension.
2. Remove the Ashlip Extension from the firebox
by grasping the sides and pulling it forward to
disengage the three clips from their adjacent
slots.
3. Remove the Surround Panel assembly by grasping the lower lip of the Breastplates and lifting
it up and off of the firebox cabinet. There are
four tabs that must be disengaged from the
hangers on either side.
4. Remove the three screws that attach the flue
connector to the flue collar, and disengage the it
from the insert.
5. Pull the firebox and cabinet forward as a unit.
The flue connector, liner, and chimney can now
be inspected and cleaned.
6. See the Installation section of this manual for
reassembly procedures.
Gaskets
Check door and glass gaskets for seal integrity.
The gaskets should be soft enough to be somewhat
resilient to the touch. Over time, gaskets will
compress and harden. Replace worn-out or hardened gaskets with the appropriate size material
available from your local Authorized Jøtul Dealer.
To check the seal of the front doors, close and latch
the doors on a dollar bill and slowly try to pull the
dollar bill free. The seal is too loose if the bill can be
easily removed. Adjust the door latch and test
again.
Gasket Replacement
See the Parts List on page 21 to order the correct
gasket material.
1. Remove the old gasket material with a pliers and
thoroughly clean the channel with a wire brush.
2. Lay out the new gasket around the channel to
determine length. Trim the gasket to leave 1”
excess.
2. Apply a small bead of furnace cement in the
channel.
3. Lightly press the new gasket into the channel,
being careful to avoid compressing or stretching
it. Trim the gasket further as necessary to allow
the tail end to slightly overlap the other end.
4. Wait ten minutes to allow the cement to set and
then close and latch the doors. Reopen the doors
and, using a damp cloth, wipe away any excess
cement that may be squeezed out from under
the gasket.

Appendix A:
Alternate Floor Protection
All floor protection materials must be non-combustible i.e.. metal, brick, stone, or mineral fiberboards.
No combustible material may be used to protect the
floor in front of the fireplace insert.
Follow this procedure to determine if a proposed alternate floor material meets the requirements listed in this manual.
R-value = Thermal Resistance
K-value = Thermal Conductivity
C-value = Thermal Conductance
1. Convert the specification to R-value;
a. If R-value is given, no conversion is needed.
b. If K-value is given with a required thickness
(t) in inches: R = 1/K X T.
c. If C-value is given: R = 1/C.
2. Determine the R-value of the proposed alternate
floor protector.
a. Use the formula in Step 1 to convert values
not expressed as “R ”.
b. For multiple layers, add R-values of each layer
to determine overall R-value.
3. If the overall R-value of the system is greater
than the R-value of the specified floor protector,
the alternate is acceptable.
Example:
The specified floor protector should be 3/4” thick
material with a K-factor of 0.84. The proposed
alternate is 4” brick with a C-factor of 1.25 over 1/8
inch mineral board with a K-factor of 0.29.
Step A. Use formula above to convert specifications
to R-value. R = 1/K x T = 1/.84 x .75 = .893
Step B. Calculate r of proposed system.
4 ” brick of C - 1.25, therefore
R brick = 1/C = 1/1.25 = 0.80
1/8 ” mineral board of K = 0.29, therefore
R mineral board = 1/.29 x 0.125 = 0.431
Total R = R brick + R mineral board =
0.8 + 0.431 = 1.231
Step C. Compare proposed system R = 1.231 to
specified R of 0.893. Since R is greater than
required, the system is acceptable.
Definitions:
Thermal Conductance =
Btu = W
C =
(Hr)(ft2)(f) (m2)(k)
Thermal Conductivity =
K =
Btu = W = (Btu)
(Hr)(ft2)(f) (m2)(k) (hr)(ft)(f)
Thermal Resistance =
R = Btu = (m2)(k) = (Btu)(inch)
(Hr)(ft2)(f) W (hr)(ft2)(f)
The Jøtul C450 Fireplace Insert requires floor
protection having a minimum insulating R-value of
2.92.
