2.4 Room ventilation

The air necessary for combustion, i.e. up to 20 m³ every hour, must be ensured in rooms where stoves with

natural flue draught are installed. The air change must occur through several fixed openings to the outside,

whose cross section must comply with the current local regulations. Such openings must be protected with

grilles and must never be obstructed.

If the air is insufficient, even the operation of an extractor hood in the room or exhaust fans can negatively affect

stove operation.

2.5 Advice on flues and connections

Flues must be made from suitable materials and perfectly insulated, with characteristics that prevent

temperature decreases.

The inner walls must be perfectly smooth without any narrowing or protrusions along the entire length, so as not

to create friction or vortices in the smoke which could cause a considerable reduction in draught.

Any cleaning and inspection doors must be perfectly closed during operation.

The flue outlets must be 0.5 m higher than any obstacles within a radius of 10 m and must end with chimney

caps or cowls having a useful outlet cross section of at least double that of the flue.

The following two figures give the data regarding the distances and positioning of chimney caps in conformity

with the provisions of UNI 10683/98.
