Chimney Requirements; Masonry Chimney; Prefabricated Chimney - Jøtul F 3 USA Installation And Operating Instructions Manual

USA/Canada
This prevents any amount of condensed or liquid
creosote from running down the outside of the pipe or
the stove top. All joints, including the flue collar
connection must be secured with three sheet metal
screws to ensure that the sections do not separate.
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

There are two types of chimneys suitable for the Jøtul
F3:
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 F3.
Masonry chimneys
When installing the Jøtul F3 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 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.
