Flues and chimneys must be constructed of suitable materials and properly insulated to prevent heat loss.
The inner walls must be perfectly smooth, with no restrictions or protrusions along the entire length so as to
avoid the creation of friction and vortices in the smoke with a consequent loss of draught.
The doors of all cleaning and inspection access points must properly closed when the cooker is in operation.
The chimney outlet must be 0.5 m higher than any obstacle located within a 10 m radius and must terminate in
a cowl or pot with a cross-sectional area at least twice that of the flue.
The two diagrams below give the positioning and clearance data for chimney cowls as prescribed by UNI
10683/98.

Before
connecting
to the requirements described above, check that there are no apertures or cracks where air could penetrate and
cause heat loss and a consequent reduction in draught.
Check also that there are no obstructions caused by foreign bodies or a buildup of soot. In cases where the flue
pipe is not perpendicular to the axis of the chimney, it is advisable to make the connections with special steel
fittings that allow angles of up to 45° . If the walls and ceiling are constructed from combustible materials, all
parts adjacent to the flue pipe must be suitably insulated. All connections must be properly sealed, particularly
the joint between the flue pipe from the stove and the chimney. If more than one stove or cooker is installed in
the building, each appliance must have its own flue. We strongly advise against making holes in the flue for the
connection of pipes from other appliances as this could impair the draught.
