During combustion thermal energy is released which implies a marked heating of the surfaces, doors, handles,
controls, glass, smoke tubes and also the front part of the appliance. Avoid contact with such elements without
protective clothing or without accessories (heat resistant gloves, control devices).
Ensure children are aware of these dangers and keep them away from the furnace during its operation.
When wrong fuel or fuel that is too damp is used, a fire could be caused by the deposits in the flue.
4.1. FIRST AID
If a fire is caused in the connection or in the flue:
a) Close the loading door and ash drawer.
b) Close comburent air registers
c) Put out the fire using extinguishers with carbon dioxide
(C02 with powders)
d) Request immediate aid of Fire Brigade
NEVER PUT OUT FIRE WITH JETS OF WATER.
When the flue stops burning have it checked out by a specialist to
identify any cracks or permeable points.
5. FLUE
Essential requirements or correct operation of the appliance:
•
the internal section must be circular;
•
it must be insulated thermally and impermeable and built with
materials resistant to heat, products of combustion and any
condenses;
•
be free of obstructions and have vertical passageway with
deviations not greater than 45°;
•
if already used must be clean;
•
comply with technical data of the instruction manuals;
If the flues were square or rectangular the internal corners must be
rounded with a radius not less than 20 mm. For the rectangular section
the maximum ratio between the sides must be
≤
1.5.
A section that is too small causes a fall in the draught. A minimum
height of 4m is recommended.
