4.1. FIRST-AID MEASURES

Should any fire arise in the stack or in the flue:
a) Close the feeding door and the ash drawer door.
b) Close the registers of combustion air
c) Extinguish the fire using carbon dioxide fire-fighting means (CO
Seek immediate intervention of FIRE BRIGADE.
d)
DO NOT EXTINGUISH FIRE USING WATER JETS
When the fire has been extinguished, let the flue check by an expert to find possible cracks and permeable
points.

5. FLUE

Essential requirements for a correct operation of the device:
• the internal section must be preferably circular;
• be thermally insulated and water-proof and produced with materials suitable to resist to heat,
combustion products and possible condensates;
• not be throttled and show a vertical arrangement with deviations not greater than 45° ;
• if already used, it must be clean;
• observe the technical data of the instructions manual;
Should the flues have a square or rectangular section, internal edges must be rounded with a radius not
lower than 20 mm. For the rectangular section, the maximum ratio between the sides must be ≤ 1.5.
A too small section causes a decrease of the draught. It is suggested a minimum height of 4 m.
The following features are forbidden and therefore they endanger the good operation of the device:
asbestos cement, galvanized steel, rough and porous internal surfaces. Figure 5 gives some examples of
execution.
