ARCA PIXEL 25 N - Combustion Product Discharge Methods

2.2 COMBUSTION PRODUCT DISCHARGE: PIXEL 25 N
2.2.1 CONNECTION WITH A CHEMINEY
The cheminey has a grat importance for thewell running of the boiler; It must be done according these requests:
• Must be built with a resistant water material and must be resistant
• must be in material impermeable and resistant to the temperature of the smokes and to their condensation;
• must have a sufficient mechanical resistance and a weak [conduttività termica];
• must be perfectly proof;
• must have a most possible vertical and straight course and the terminal part must be equipped with a static aspirator
that assures an efficient and constant evacuation of the smokes;
• for avoid that the wind could create around the chimney pot of the zones of such pressure from prevail on the
ascensional strength of the gases of unloaded it is necessary that the orifice of evacuation overhangs of at least 0,4 mt.
any adjacent to structure the same fireplace (inclusive the height of the roof of the building) if distant less of 8mt.;
• the cheminey must have a diameter not inferior to that of cloack of the boiler to square or rectangular section the
inside section must be plus then 10% as regards that of exit of the same cloak;
• beginning from the cloak, the link must have a vertical pull of length not inferior to two turned the diameter before the
cheminey
2.2.2 OUTDOOR DIRECT DISCHARGE
The natural draught boilers could unload the smokes directly to the outside through the building wall ; a terminal of
draught to the extremity of the duct must be applied.
The duct must satisfy the followings requisite:
• the horizontal inside part to the building must be reduced to the minimum ([1mt.) and have an inclination in equal
slope at 3 o'clock% toward the outside;
• must not have more than two changes of direction;
• must receive the unloading of an only apparatus;
• must be protected;
• the pull external ending before the terminal of draught must stick out from the wall of at least two diameters;
• the vertical leaving pull from the cloak must be along at least a meter;
• the terminal of draught must overhang of at least 1,5mt. the attack of the duct on the cloak of the boiler.
la parte orizzontale interna all’edificio deve essere ridotta al minimo (max. 1mt.) ed avere un’inclinazione
2.2.3 VENTING OF THE ROOMS
The natural draught boilers are of open combustion to room and are scheduled for have laced the cheminey:
the combustive air has withdrawn directly from the environment in which the boiler is installed.
The rooms in which the boiler is placed will be able to have a ventilation of direct type (with taking of air in
the same place where the boiler is installed), or have an indirect ventilation (with taking of air in the adjoining
places) provided that they come respect the conditions under suitable:
DIRECT AIRING
• the place must have an opening of equal airing to 6 cm² for each installed [kW] and in all the cases
never inferior to 100cm², practiced directly on the wall toward the outside;
• the opening must be nearest possible to the floor;
