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.
2.0 Chimney requirements
There are two types of chimneys suitable for the Jøtul F
3
:
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 cross-
sectional 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
ce of the chimney, as well as the proximity of surrounding
trees or buildings.
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 (ANSI-NFPA
211 for 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 Jøtul F
3
.
CHIMNEY INSPECTION:
A Level II (camera) inspection
of an existing chimney system must be conducted by
a qualified technician as specified by NFPA 211 when
verification of the suitability of the chimney for new or
changed conditions of service is needed or when a Level
I inspection is not sufficient to determine serviceability
of the chimney.
Masonry chimneys
When installing the Jøtul F
3
into a masonry chimney you
must conform to all of the following guidelines:
• The chimney flue size should not be less than the cross
sectional area of the stove flue collar.
• The cross-sectional area of the flue of a chimney with
no walls exposed to the outside below the roofline
shall not be more than three times the crosssectional
area of the stove flue collar.
• The cross-sectional area of the flue of a chimney with
one or more walls exposed to the outside below the
roofline shall not be more than two times the cross-
sectional area of the stove flue collar.
• Larger chimney flues should be relined with a listed or
code approved liner.
• 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 1/2” 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 8”x 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.
• 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 UL103 for the U.S. And high temperature
standard ULC S-629 for Canada.
The manufacturer’s 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.
