JØTUL F 3 CB WOODSTOVE
When installing, operating and maintaining your
Jøtul F 3 CB woodstove, follow the guidelines
presented in these instructions, and make them
available to anyone using or servicing the stove.
A number of areas require a building permit to install
a solid fuel burning appliance. In the U.S., the
National Fire Protection Associations 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.
· BE SURE TO READ THIS ENTIRE
MANUAL BEFORE YOU INSTALL OR USE
YOUR NEW JØTUL F 3 CB WOOD STOVE.
· 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
EVEN DEATH.
· Jøtul recommends that you have your new Jøtul
F 3 CB installed by a professional installer of solid
fuel burning appliances.
· EXTREMELY HOT WHILE IN OPERATION!
KEEP CHILDREN, CLOTHING AND
FURNITURE AWAY. CONTACT MAY
CAUSE SKIN BURNS.
· Avoid creating a low pressure condition in the
room where the stove is operating. Operating an
exhaust fan or a clothes dryer could create a low
pressure area, causing poisonous gases to come
out of the stove into the room.
You can prevent low pressure conditions by
providing adequate combustion air within 24 but
not closer than 12 from the stove. Or, simply
install the optional outside air manifold system,
which allows the direct connection of air from
outside the house to the stove.
· Do not use chemicals or fluids to start the fire.
Some fuels will, during combustion, separate
carbon monoxide and generate it in the burn
chamber. Carbon monoxide is toxic, so please
follow the guidelines in this manual for proper
operation of your Jøtul F 3 CB.
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.
· If you for some reason experience smoke rollout from the stove, it may activate smoke
detectors if installed in the house.
DO NOT CONNECT THIS STOVE TO ANY
AIR DISTRIBUTION DUCT OR SYSTEM.

ABOUT RESTRICTIONS AND INSTALLATION
INSPECTION REQUIREMENTS IN YOUR AREA.
Reminder:
Your local officials have final authority in
determining if a proposed installation is acceptable.
Any requirement, that is requested by the local
authority having jurisdiction, that is not specifically
addressed in THIS manual, defaults to NFPA 211,
and local codes in the U.S. or in Canada, CAN/
CSA-B365-M and local codes.
INSTALLING THE VENTING
The F 3 CB can be vented from the top, the rear or
from either the right or left side. Follow the
instructions below for the desired venting location.
TOP EXIT VENTING
When top exit venting is desired, use a 3mm allen
wrench to remove the two set screws that secure
the top casting to the sides of the stove and lift off
the top casting. Lay the top casting on a flat surface
upside down and remove the 10mm bolt from the
traverse bar and remove the smoke outlet cover.
Reinstall the top casting, be sure to secure with the
two set screws that were removed. See figure 1.
When rear exit venting is desired it will be necessary
to knock-out the vent hole from the rear casting.
Remove the top casting of the stove by removing the
two 3mm set screws that secures the top to the sides.
The set screws are located on the outside of the stove
on the top of each side panel.
Using a 10mm wrench remove the double rear
heatshields from the back of the stove. Remove the
front door to avoid damage to the glass.
Reminder:
loss of the door washer will result in improper door
alignment when reinstalling the door.
Using a claw hammer or a small sledge hammer
strike the CENTER of the 6 knock-out disc from
the OUTSIDE of the stove. The knock-out disc
will break into four wedges and may need to be tapped
out. Touch up any remaining sharp edges with a file
or hand grinder.
NOTE: The IVORY F 3 CBs ARE REAR
VENTED FROM THE FACTORY. IT IS NOT
NECESSARY TO KNOCK-OUT THE REAR
CASTING OF THE STOVE. HOWEVER, IF TOP
EXIT IS DESIRED IT IS NECESSARY TO
INSTALL A SMOKE OUTLET COVER ON THE
REAR OUTLET OF THE STOVE.

STOVE PIPE
CHIMNEY CONNECTOR
The chimney connector is a single walled pipe used
to connect the stove to the chimney. For use with the
F 3 CB the chimney connector MUST be 6 in
diameter, with a minimum thickness of 24 gauge black
steel.
Aluminum and Galvanized steel pipe is not acceptable
for use with the F 3 CB. These materials cannot
withstand the extreme temperatures of a wood fire
and can give off toxic fumes when heated.
Each chimney connector or stove pipe section must
be installed to the stove flue collar and to each other
with the male (crimped) end toward the stove. See
figure 5.
INSTALLING THE STOVE PIPE ADAPTER
After the appropriate flue outlet in the stove has been
established the stove pipe adapter (included with every
stove) must be installed so that standard stove pipe
can be installed onto the stove.
Insert the end of the adapter with the four holes into
the stove. These holes allow the adaptor to be
attached to the stoves internal collar, using the nuts
and bolts provided with the stove. See figure 3.

double walled stove pipe. See figure 4.
Each joint of chimney connector or stove pipe must
be secured with at least three sheet metal screws to
ensure that the sections do not seperate.

FIGURE 5
For the best performance the chimney connector
should be as short and direct as possible, with no more
than two 90° elbows. The maximum horizontal run is
36 and a recommended total length of stove pipe
should not exceed 10 feet. Always slope horizontal
runs upward ¼ per foot toward the chimney.
No part of the chimney connector may pass through
an attic or roof space, closet or other concealed space,
or through a floor or ceiling. All sections of the
chimney connectors must be accessible for cleaning.
Where passage through a wall or partition of
combustible construction is desired, the installation
must conform with NFPA 211 or CAN/CSA-B365,
and is also addressed in this manual.
DO NOT CONNECT THIS UNIT TO A
CHIMNEY FLUE SERVICING ANOTHER
APPLIANCE.
Do not use the connector pipe as a chimney.

CHIMNEY REQUIREMENTS
Masonry Chimneys
There are two types of chimneys suitable for the
F 3 CB:
1. A code- approved masonry chimney with a flue
liner.
2. A prefabricated chimney complying with the
requirements for Type HT (2100°F) chimneys
per UL 103 or ULC S629.
The chimney size should not be less than the crosssectional area of the flue collar, and not more than
three times greater than the cross-sectional area of
the flue collar.
When selecting a chimney type and the location for
the chimney in the house, keep this in mind: it is the
chimney that makes the stove work, NOT the stove
that makes the chimney work. This is because a
chimney actually creates a suction, called draft
which pulls air through the stove.
Several factors affect draft: chimney height, crosssectional area (size), and temperature of the chimney,
as well as the proximity of surrounding trees or
buildings.
When installing the F 3 CB into a masonry chimney
you must conform to all of the following guidelines:
· The masonry chimney must have a fireclay liner
or equivalent, with a minimum thickness of
5/8 and must be installed with refractory mortar.
There must be at least ½ air space between
the flue liner and chimney wall.
· The fireclay flue liner must have a nominal size
of 8 X 8, and should not be larger than
8X 12. If a round fireclay liner is to be used it
must have a minimum inside diameter of 6 and
not larger than 8 in diameter. If a chimney with
larger dimensions is to be used, it should be
relined with an appropriate liner that is code
approved.
· The masonry wall of the chimney, if brick or
modular block, must be a minimum of 4 nominal
thickness. A mountain or rubble stone wall must
be at least 12 thick.
· A newly-built chimney must conform to local
codes and in their absence must recognize
national regulations.
As a result, a short masonry chimney on the exterior
of a house will give the poorest performance. This
is because it can be very difficult to warm the
chimney thereby creating inadequate draft. In
extremely cold northern areas it may be necessary
to reline the chimney or extend its height to help
establish draft.
Oppositely, a tall masonry chimney inside the house
is easier to keep warm and will perform the best.
The following guidelines give the necessary chimney
requirements based on the national code (ANSINFPA 211for the US. And CSA CAN-B365 for
Canada). However, many local codes differ from
the national code to take into account climate,
altitude, or other factors. It is important that you
check with your local building officials to find out
what codes apply in your area before installing your
new F 3 CB.
· When using an existing chimney, it must be
inspected by a professional licensed chimney
sweep, fire official, or code officer, to ensure
that the chimney is in proper working order.
· No other appliance can be vented into the same
flue.
· An airtight clean-out door should be located at
the base of the chimney.
Prefabricated Chimneys
If a prefabricated metal chimney is to be used it
must be a chimney type that is tested and listed for
use with solid fuel burning appliances. High
Temperature (HT) Chimney Standard UL 103 for
the U.S. and High Temperature Standard ULC
S-629 for Canada.
6
The manufacturers installation instructions must be
followed precisely. Always maintain the proper
clearance to combustibles as established by the pipe
manufacturer. This clearance is usually a minimum
of 2, although it may vary by manufacturer or for
certain chimney components.
Chimney Height
Whether a masonry chimney or prefabricated metal
chimney is used it must be the required height above
the roof line.
The requirement is:
The chimney must be at least 3 feet higher than the
highest point where it passes through the roof and at
least 2 feet higher than the highest part of the roof or
structure that is within 10 feet of the chimney,
measured horizontally. See figure 6.
WALL PASS-THROUGHS
When your installation unavoidably requires the
chimney connector to pass through a combustible wall
to reach the chimney, always consult your local
building officials, and be sure any materials to be used
have been tested and listed for wall pass-throughs.
In the U.S.
The National Fire Protection Associations publication,
NFPA 211, Standard for Chimneys, Fireplaces,
Vents and Solid Fuel Burning Appliances permits
four methods for passing through a combustible wall.
Before proceeding with any method be sure to consult
with your local building officials to discuss any local
code requirements.
Common Method
When passing through a combustible wall to a
masonry chimney this method requires the removal
of all combustible materials from at least 12 around
the chimney connectors proposed location. With a 6
round liner the minimum area required would be 31
x 31 square.
FIGURE 6
Chimneys shorter than 14 feet may not provide
adequate draft. This could result is smoke spilling
into the room from the stove when loading the stove,
or when the door is open. In addition, inadequate
draft can cause back puffing, which is a build up of
gases inside the firebox.
Other times, chimney height can create excessive
draft which can cause high stove temperatures and
short burn times. Excessive drafts can be corrected
by installing a butterfly damper. If you suspect you
have a draft problem, consult your dealer.
The space is then filled with at least 12 of brick
around a fireclay liner. Remember, the liner must be
ASTM C35 or equivalent, with a minimum wall
thickness of 5/8.
It is important to remember to locate the pass-through
at least 18 from the ceiling for proper clearance to
combustibles.
It will be necessary to cut wall studs, install headers,
and construct a sill frame to maintain the proper
dimensions and to support the weight of the brick.
The bricks must be solid brick with a minimum of
3 ½ thick (4 nominal).
Refractory mortar must be used at the junction of the
chimney and the pass-through liner. The pass-through
liner must not penetrate the chimney liner beyond the
inner surface of the chimney liner. Use extreme care
when constructing the hole in the chimney liner, the
tiles can shatter easily. See figure 7
.
