Prefabricated Chimneys
These should be an internal diameter of 150 mm (6”)
and be of the twin wall insulated construction that has
been approved for solid fuel use (e.g. Rite Vent ICS of
ICID Lite Chimney Systems). Diameters over 00 mm
(8”) are not recommended due to the large cross-sec-
tion causing excessive cooling of the flue gases.
A horizontal connector run should be inclined 1/4” per
foot (0 mm per meter) from the stove toward the
chimney. The recommended maximum length of a hori-
zontal run is 3 feet (1m) and the total length of chimney
connector should be no longer than 8 feet (.5m).

Chimney Size
The Model 460CE and 461CE heaters should be
vented into a masonry chimney with a square flue with
nominal flue size of 03 x 03 mm (8” x 8”), or a round
flue with nominal flue size of 15 mm (6”). The Model
46CE heater should be vented into a masonry chim-
ney with a nominal flue size of 03 x 03 mm (8” x 8”)
square, or 03 mm (8”) round.
Chimney liners larger than 03 x 305 mm (8” x 1”)
may promote rapid cooling of smoke and reduction in
draft, especially if they are located outside the home.
These large chimneys may need to be insulated or
have their flues relined for proper stove performance.
Accessories to help make the connection between
stainless steel chimney liners and the stove are avail-
able through your local dealer.
Guidelines for Installing
the Chimney Connector
The chimney connector is the single-wall pipe, or listed
and approved double-wall pipe that connects the stove
to the chimney. The chimney itself is a masonry or
prefabricated structure that encloses the flue. Chimney
connectors are used only to make the connection from
the stove to the chimney.
Connecting Flue Pipes
Connector pipes should meet the requirements of the
building regulations. This can be achieved by the use
connecting fluepipes included in the following catego-
ries:
a) Vitreous enamelled steel pipe complying with BS
6999: 1989 (1996);
b) Pipes made from stainless steel as descirbed in BS
EN 1008-1:1995 grades 1.4401, 1.4404, 1.443 or
1.4436 with flue wall thickness of at least 1 mm;
c) Mild steel fluepipes complying with BS 1449: Part 1:
1991, with a flue wall thickness of at least 3 mm;
d) Cast iron fluepipes complying with BS 41: 1973
(1998).
Flue Pipes with a spigot and socket joint should be
fitted with the socket facing upwards, to contain con-
densates and moisture within the flue. Joints should be
made gas tight using proprietary jointing accessories,
or, where appropriate, by packing joint with noncombus-
tible rope and fire cement.
Do not pass the chimney connector through a combus-
tible wall or ceiling, or through an attic, a closet or any
similar concealed space. If passage through a combus-
tible wall is unavoidable, follow the recommendations in
the following section on Wall Pass-Throughs. Keep the
passage as short and direct as possible, with no more
than two 90 degree turns.
Two Types of Connector
You may use either a single-wall steel connector of the
size and gauge described below, or a listed and ap-
proved double-wall connector.
Single-Wall Connector
The single-wall chimney connector should be made of
4 gauge or heavier steel, and must have a minimum
internal diameter of 15 mm (6”) for models 460CE
and 461CE, or 03 mm (8”) for model 46CE.
Install single-wall chimney connector not less than
450mm (18”) from the ceiling.
In cathedral ceiling installations, extend the prefabricat-
ed chimney downward to within .5 m (8”) of the stove.
The entire chimney connector should be exposed and
accessible for inspection and cleaning.
Do not use galvanized chimney connector; it cannot
withstand the high temperatures that can be reached
by smoke and exhaust gases and it may release toxic
fumes under high heat.
