Answer: yes, the maintenance of the gas VMC must be carried out by a professional.
Yes, gas VMC requires specific maintenance which must be carried out by a specialist. On the one hand, the regulations require that the gas VMC be fitted with a safety system, in the event of the gas boiler extractor stopping, in the form of a thermal switch or a pressostatic switch . On the other hand, in order to reduce the risk of fire, the gas VMC must undergo regular maintenance provided by a professional in the sector, and not by the owner himself. Each year, the blades and vents of the VMC must be cleaned and the electrical connections checked. Every five years, the overall installation must be checked and all the devices connected, in particular the safety device, checked. You too, send us your brico question
