5.6 FLUE GAS EXHAUST
The stove operates with negative pressure in the
combustion chamber, and consequently the flue
gas discharge and corresponding joints must be
airtight.
The stove must be connected to its own
separate flue gas exhaust system capable of
ensuring adequate atmospheric dispersion of the
combustion by products.
The components making up the flue gas exhaust
system must be suitable for the specific operating
conditions and bear the CE mark.
The size of the flue gas exhaust must conform with
the UNI EN 13384-1 standard.
The flues should be suitably insulated (e.g. using
rock wool) or made using double wall steel pipes,
except for the initial vertical section inside the
room.
There should be at most three changes in direction
along the flue, not exceeding 90°, including the
chimney connection, with the horizontal length of
the flue not exceeding 2 metres.
Use always connector with inspection cap on all
horizontal or vertical changes in flue direction.
Anchor the flues to the wall using special collars.
The flue gas exhaust attachment MUST NOT BE
connected to:
• a chimney used by other heat generators
(boilers, stoves, fireplaces, etc.....);
• air exhaust systems (range hoods, vents, etc.....)
even if these are ducted.
Shut-off or draught valves must not be used.
Combustion byproducts must be discharged
through the roof.
The stove can be connected to the flue gas exhaust
above or behind the stove (fig. 5.3). In the latter
case it is necessary to disassemble the upper collar
and replace the plug on the back of the stove with
it. The rear plug must be screwed onto the upper
part.
• Comply with the directions given on the data
sheet regarding the draught of the chimney.
