INSERTO 50 – 80 – 100

4.1. FIRST-AID MEASURES

Should any fire arise in the stack or in the flue:
a) Close the feeding door.
b) Close the registers of combustion air
c) Extinguish the fire using carbon dioxide fire-fighting means (CO
d) Seek immediate intervention of FIRE BRIGADE.
DO NOT EXTINGUISH FIRE USING WATER JETS.
When the flue does not burn any more please arrange an examination by a specialist in order to find
possible cracks and permeable points.

4.2. BEAM PROTECTIONS

Considering the irradiation of the hearth, it is necessary to be particularly careful in protecting the beams
while designing your stack. Consider the proximity of beams to the external surfaces of the hearth, on one
side, and the irradiation of the glass door, usually very close to the beams, on the other side. In any case, it
has to be considered that the internal or lower surfaces of this beam in flammable material must not come
in contact with temperatures higher than 65 ° C.

WARNING:
We cannot be made liable for a wrong operation of the plant, when it does not comply with the
provisions of these instructions or when it uses additional products not suitable for this appliance.

5. 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.
