2.5 Advice on flues and connections
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.
