between the flue liner and chimney wall.
• The fireclay flue liner must have a nominal size of 8”
X 8” (20 cm x 20 cm), and should not be larger than
8”X 12” (20 cm x 30 cm). A round fireclay liner must
have a minimum inside diameter of 6” (15 cm) and
maximum inside diameter of 8” (20 cm). A larger
chimney should be relined with an appropriate code
approved liner.
• Brick or modular block must be a minimum of 4” (10
cm) nominal thickness. Stone construction must be
at least 12” (30 cm) thick.
• A newly-built chimney must conform to local codes,
or, in their absence, must comply with national
regulations.
• An existing chimney 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 may be vented into the same flue.
• An airtight clean-out door should be located at the
base of the chimney.
Prefabricated Chimneys
A prefabricated metal chimney must be 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.
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.
Chimney Height
The chimney must be at least 3 feet (92 cm) higher than
the highest point where it passes through the roof and
at least 2 feet (61 cm) higher than the highest part of
the roof or structure that is within 10 feet (3.05 m) of
the chimney, measured horizontally.

2.0 Chimney Requirements
There are two types of chimneys suitable for the Jøtul
F
100
:
1. A code-approved masonry chimney with a ceramic
tile or listed steel 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 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, cross-
sectional area (size), and temperature of the chimney,
as well as the proximity of surrounding trees or
buildings.
A short exterior masonry chimney will give the poorest
performance because it will be difficult to warm
the flue and sustain the temperatures necessary to
maintain draft strength. In extremely cold climates, it
may be necessary to reline the chimney or extend the
height to help establish draft.
A tall, interior masonry chimney is easier to keep warm
and will perform the best under a variety of weather
and environmental conditions.
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. Your
local building inspector is the final approving authority.
Consult them prior to installation.
Do not connect the stove to any air distribution duct
or system.
Masonry Chimneys
When installing the Jøtul F
100
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” (14
mm) and must be installed with refractory mortar.
There must be at least 1/2” (12.7 mm) air space
