USA /Canada
There must be at least 1/2” (12.7 mm) air space 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. See figure 4.
Chimney Requirements
There are two types of chimneys suitable for the Jøtul
F 100 USA :
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 USA 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.
