THE MANUFACTURER DECLINES ALL RESPONSIBILITY FOR DAMAGE TO PERSONS OR THINGS
CAUSED BY NON-OBSERVANCE OF THE ABOVE PRESCRIPTIONS.
16.2 Ventilation requirements
The room containing the appliance should have an air supply in accordance with the standards in force.
The room where the appliance is installed must have enough air flow as required for the regular
combustion of gas and by the necessary air exchange of the same room. The air vent, protected by
grills, must be suitably dimensioned in compliance with the current regulations and positioned so that no
part of it is obstructed.
16.3 Extraction of the products of combustion
Extraction of the products of combustion must be ensured by means of hoods connected to a natural
draught chimney whose efficiency is assured or via forced extraction. An efficient extraction system
requires precision planning by a specialist qualified in this area and must comply with the positions and
distances indicated by the regulations. When the job is complete, the installer must issue a certificate of
conformity.
16.4 Connection to gas
Installation of the UNI-CIG 7140 compliant rubber hose must be carried out so that
the hose length is no greater than 1.5 metres. Make sure that the hose does not
come into contact with moving parts or is squashed. The inside diameter of the hose must be 8 mm for
LPG.
LIQUID and 13 mm for METHANE GAS and TOWN GAS.
Verify that all the follow conditions are met:
• the hose is fixed to the hose connection with safety clamps;
• no part of the hose is in contact with the hot walls (max. 50 °C);
• the hose is not under traction or tension and has no tight curves or twists;
• the hose is not in contact with sharp objects or sharp corners;
• if the hose is not perfectly airtight and leaks gas, do not try and repair it: replace it with a new hose;
• verify that the hose is not beyond its life cycle (serigraphed on the hose itself).
