Table 28 - Table of technical problems
(1) This control is activated 120 seconds after the activation of the pump and only during the request for CH (without domestic hot water).
(2) Fault 81 can be caused by an obstruction in the flue gas outlet. In this case it is advisable to contact the assistance center before
unlocking the boiler.
ATTENTION
Gas boilers are electrical and electronic devices (EEE) and when they are decommissioned they become electrical and electronic waste
(WEEE): as such they must be disposed of in compliance with current legislation.
Gas boilers are classified as domestic appliances and must be disposed of together with washing machines, dishwashers and dryers
(WEEE R2 waste).
The dismantling of gas boilers and their disposal through channels not specifically provided for by law is prohibited by law.
The user has the right to be able to confer the decommissioned gas boiler, intact in its construction, in the ecological island of the
municipality in which he is a resident.
The installer and the user have the right to be able to deliver the decommissioned gas boiler, intact in its construction, on a one-to-one
basis, to the point of sale where they purchase the new gas boiler.
