2.4 Fume exhaust
The fumes can be exhausted through a connection to a conventional flue or an external duct with double wall or
insulated pipe.
The fume exhaust connections must guarantee a minimum draught of 10 Pa so that the evacuation of fumes is
assured in case of a temporary power failure.
- The installer must check the efficiency and state of the flue and its conformity with the
local, national and European regulations.
- Certified pipes and connections with adequate seals guaranteeing their tightness must be used.
- In case of fire, shut down the stove, promptly call the fire department, and avoid continual attempts
to extinguish it.
- Clean the flue and respective connection at least once a year.
2.4.1Types of installation
Listed below are definitions and requirements for correct installation of an exhaust flue in accordance with Italian
Standard UNI10683:
FLUE : a vertical duct for collecting and expelling, at an appropriate height
from ground, the fumes coming from a single unit and, where permitted,
more than than one.
FLUE technical requirements :- it must be fumetight, isolated and insulated
depending on its use;
- it must have a mainly vertical path with axis deviation < 45°;
- it must be at a suitable distance from flammable materials with insulation
or air gap;
- it must preferably have a constant, free and independent round internal
section;
- it is advisable for the flue to have an inspectionable chamber for the
collection of solid materials
- and any condensate, placed under the beginning of the fume duct.
FLUE CONNECTION or DUCT: duct or connection element between the
unit and flue for evacuation of fumes.
DUCT technical requirements: - it must not cross rooms in which the
installation of combustion units is not allowed;
- flexible metal tubes or fibre cement pipes are prohibited;
- the use of counter-sloping elements is prohibited;
- horizontal sections must have an upward slope of at least 3°;
- the length of the horizontal section must be minimal and not more than 3 m;
- there must not be more than 3 changes of direction, without the T union;
- with change of direction > 90° a max. of 2 bends can be used with length in horizontal projection not exceeding 2 m.
- the fume duct must have a constant section and allow the recovery of soot.
CHIMNEY CAP : a device placed on the top of the flue to facilitate the dispersion of fumes into the atmosphere.
CHIMNEY CAP technical requirements : - it must have a section equivalent to that of the flue;
- it must have a useful section not less than double the internal section of the flue;
- it must prevent the entry of rain and foreign bodies and ensure the discharge of fumes in any
atmospheric condition;
- it must ensure an adequate dilution of fumes and be positioned outside the backflow area;
- it must be without mechanical means of suction.
The direct discharge of fumes must take place on the roof and not towards closed spaces
(even open air).
2.5 Brazier and baffle position check
Before lighting the stove make sure the brazier is in the correct position, i.e. fitted in the special slots. Also make
sure the top smoke baffle is properly fitted. A wrongly positioned baffle can result in malfunctioning and excessive
blackening of the glass.
At every stove lighting, check the correct position of the brazier on the brazier holder.
