4.1 4.1 FLUE PIPE FLUE PIPE
THE PRODUCTION OF STOVES WITH HIGHER PERFORMANCE IS INCREASINGLY REQUIRED SO IT IS
BECOMES ESSENTIAL TO ENSURE THAT INSTALLATIONS COMPLY WITH THE LAW. IF THE VENT PIPE
PASSES THROUGH NON-HEATED ENVIRONMENTS, IT MUST BE INSULATED FOR CORRECT COMBUSTION.
The vent 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 vent pipes are made of steel, either
stainless steel or aluminised.
● To make fitting of the rigid steel flue pipe easier, we recommend using telescopic connectors, which will also compensate
for the thermal dilation both of the fire box and the flue pipe itself.
● Seal the vent pipe joint connection with high temperature silicone sealant (1,000°C). Should the existing flue opening not
be perfectly perpendicular to the firebox fume outlet, use an elbow to connect them. The inclination, with respect to the
vertical, must never exceed 45° (see figure to the side) and there must be no bottlenecks.
● No constrictions. Use 10cm-thick insulating thimbles if pipe vent passes through floors.
● The vent pipe must be insulated along its entire length. Thanks to the vent pipe, insulation fume temperature will remain
high optimising draught, preventing condensation and reducing the build-up of non-ignited particles along the vent pipe
walls. Use proper insulating materials (glass wool, ceramic fibre, Class A1 non-combustible materials).
● The flue must be waterproof and must not make more than two changes of direction.
● The use of double-walled metal hoses in certified steel is permitted if installation with a rigid tube is not possible. The use
of flexible metal and extensible aluminium pipes is not allowed.
ATTENTION ATTENTION
The flexible system can only be used inside the chimney for the vertical section and must be fixed to a rigid T-
coupling, do not use for the fume duct pipe.

Avoid vent pipes with internal rectangular section
whose ratio between the larger and smaller side
is greater than 1.5. Poor efficiency
