2.0 Plan Ahead
A safe stove installation involves several elements,
including:
(2.1)
the chimney connector,
(2.2)
the chimney
itself,
(3.0)
the connection between the chimney connector
and chimney, and
(4.0)
protection of combustible materials
in the vicinity of the stove. Each of these elements is equally
important for a safe stove installation.
2.1 Chimney Connector (Stove Pipe)
Chimney connector is also sometimes called stove pipe or
flue pipe, and it is used to connect the stove to the chimney.
The chimney connector should be 6” diameter black steel,
with a minimum thickness of 24 gauge.
Do not use aluminium or galvanized steel pipe as a
chimney connector. These materials cannot withstand the
extreme temperatures of a wood fire and can give off toxic
fumes when heated.
Matching enamel pipe is available for your Jøtul F
602
CB.
Contact your Authorised Jøtul dealer for more information.
Do not use chimney connector pipe as a chimney.
The factory-supplied adapter must be used for fitting the
stove’s flue collar to the chimney connector.
Chimney connector sections must be attached to the
stove’s flue collar adapter and to each other with the
crimped end toward the stove
(fig. 2, page 23)
.
The space between the flue collar adapter and the chimney
connector should be sealed with stove cement or an
appropriately size piece of gasket. This allows any small
amounts of condensed creosote to run into the stove
rather then onto the outside of the pipe or the stove top.
All joints, including the adapter to the flue collar, should
be secured with three sheet metal screws to ensure that
the sections will not separate.
For proper operation the chimney connector should be
as short as possible. Horizontal lengths should have an
upward slope from the stove of 1/4” per foot. Avoid using
more than two 90 degree elbows or total runs of pipe
greater than 1 0’.
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. Whenever possible, avoid passing
the chimney connector through a combustible wall.
Wall Pass-Through
When your installation unavoidably requires that the
chimney connector pass through a combustible wall to
reach the chimney, extreme care must be taken. In the
U.S., the National Fire Protection Association’s publication
NFPA 21 1, Standard for Chimneys, Fireplaces, Vents, and
Solid Fuel Burning Appliances, permits four methods for
passing through a combustible wall. In Canada, refer to
CAN/CGA B356.
Before beginning the installation, contact local building
officials to make sure the proposed pass-through method
meets local building code requirements.
A commonly used method to pass through a wall directly
to a masonry chimney requires removal of all combustible
material from at least 12” around the entire chimney
connector. The space is then filled with at least 12” of brick
around a fireclay liner. Be sure to locate it so that the top of
the chimney connector will be at least 18” below the ceiling.
To construct the brick pass-through, you will need an
opening of 30” x 30” minimum. It will be necessary to cut
wall studs, install headers, and construct a sill frame to
maintain proper dimensions and to hold the weight of
the brick. Minimum 3-1/2” (4” nominal) thick solid bricks
are to be used.
The fireclay liner (ASTM C35 or equivalent), minimum
5/8” wall thickness, must not penetrate into the chimney
beyond the inner surface of the chimney flue liner and
must be firmly cemented in place. If it is necessary to cut a
hole in the chimney liner, use extreme care to keep it from
shattering. Refractory mortar must be used at the junction
to the chimney liner.
(See figure 3, page 23)
An approved installation that uses a section of listed solid
fuel insulated factory-built chimney as a pass- through
for the chimney connector, must have an inside diameter
which is 2” larger than the chimney connector- a minimum
length of 12” -and at least 1” of insulation thickness. The
chimney section is installed with at least 2” of air space
between the outer chimney wall and adjacent combustible
materials.
Sheet steel support plates are used on both ends of
the chimney section to keep the connector centred. The
opening around the chimney section is closed on both
sides of the wall with sheet steel plates and the chimney
section is securely fastened to the plates. Fasteners used
to support the chimney section should never penetrate
the inner flue liner.
See NFPA-211 for other approved wall passthrough
methods.
2.2 Chimneys
There are two types of chimneys suitable for the
Jøtul F
602
CB. An approved masonry chimney, or a listed
residential-type building heating appliance chimney.
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
suction, called draft, which pulls air through the stove.
Several factors affect draft: the height, cross-sectional area,
and temperature of the chimney, as well as the proximity
of surrounding trees or buildings.
