Air Inlet; Types Of Installation - Cola AQUAPLUS 23 Installations-, Bedienungs- Und Wartungsanleitung

2.3 Air inlet

The stove air inlet pipe or intake is located at the back and is round and 50 mm in diameter.
The combustion air can be sucked:
►
from the room, provided there is a wall air inlet near the stove, communicating with the outside and of minimum
area 100 cm² suitably protected externally by a grille;
►
or with connection directly to the outside with a suitable pipe of inside diameter 50 mm and max. length 1.5 m.
2.4 Fume exhaust
Fumes can be exhausted through a connection to a conventional flue.
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.

2.4.1 Types 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 ).
