During the combustion will be spread thermal energy which warms up the surfaces, the door, the fireplace glass, the
handles and knobs, the smoke pipe and the front side of the stove. Please avoid the contact of these parts without
gloves or the relevant tools.
Warn children of the danger and keep them away during the operation of the stove .
The use of a wrong or wet fuel causes the formation of creosote deposits in the flue and will fuel a chimney fire.

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 controls of combustion air
c) Extinguish the fire using carbon dioxide fire-fighting means (CO
d) Seek immediate intervention of FIRE BRIGADE.

FLUE

Essential requirements for a correct operation of the appliance:
• 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 appliance: asbestos
cement, galvanized steel, rough and porous internal surfaces. Picture 7 gives some examples of execution.
The minimum section must be 4 dm
than 200 mm, or 6.25 dm
The draught created by the flue must be sufficient, but not excessive.
