Chimney Requirements; Masonry Chimney - Jøtul F3 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 1/4" 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.

2.0 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.

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 F3 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.
