05. FLUE PIPE
IPCN11,5
Chimney flue draught
11 Pa
Fume temperature
180 °C
Flue gas mass flow
9.1 g/s
IMPORTANT: THE LENGTH OF THE FUME DUCT PIPE MUST HAVE A DIAMETER EQUAL TO OR GREATER THAN THAT SPECIFIED FOR EACH
APPLIANCE. EVERY 90° ELBOW OR (T) COUPLING IS THE EQUIVALENT OF 1 METER OF PIPE.
IN ORDER TO GUARANTEE CORRECT EFFICIENCY OF THE STOVE, ENSURE THE FOLLOWING TYPES OF INSTALLATION BEFORE CONNECTION TO
THE FLUE PIPE:
INSTALL THE PRODUCT WITH AT LEAST 1 METER OF TUBE CERTIFIED ACCORDING TO THE EN 1856-2 STANDARD
The flue pipe is one of the key features for guaranteeing the proper functioning of the stove. Thanks to the quality of
the materials, the strength, the durability, the easy cleaning and maintenance, the best flue pipes are made of steel,
either stainless steel or aluminised.
•
In order to facilitate connection to the rigid steel flue, it is advisable to use telescopic fittings which, in addition to
facilitating the procedure, also compensate for the thermal expansion of both the firebox and the flue itself.
•
It is advisable to seal the flue pipe at the end of the appliance with silicone resistant to high temperatures
(1,000°C). Should the existing flue opening not be perfectly perpendicular to the firebox fume outlet, use an elbow
to connect them. The angle with respect to the vertical, must never exceed 45° (see figure to the side) and there
can be no bottlenecks.
•
No constrictions. Use 10cm-thick insulating thimbles if pipe vent passes through floors.
•
The flue pipe must be insulated along its entire length. The insulation will make it possible to maintain a high
fume temperature. To optimise the draught, avoid condensation and reduce deposits of unburnt particles on the
walls of the flue. Use proper insulating materials (glass wool, ceramic fibre, Class A1 non-combustible materials).
•
The flue must be weatherproof and must not make more than two changes of direction.
•
Flexible and length-adjustable metal pipes may not be used.
EXISTING FLUE PIPE (TRADITIONAL)
FLUE PIPE TYPES
Steel flue pipe with double chamber insulated with
material resistant to 400°C. Optimum efficiency.
Refractory flue pipe with insulated double chamber and
external coating in lightweight concrete. Optimal
efficiency.
Avoid flue pipes with internal rectangular section whose
ratio between the larger and smaller side is greater than 1.5.
Poor efficiency
Traditional clay flue pipe with cavities. Optimal efficiency.
