1.6 Regole e regolamentazioni
(direttive, leggi, normative)
-Gli impianti termici, seppur correttamente
utilizzati, sono inevitabilmente soggetti
a fenomeni di usura determinati dalle
sollecitazioni termiche e meccaniche cui
sono sottoposti nel tempo.
-Il regolare funzionamento di un impianto
termico pertanto, è subordinato
all’esecuzione di controlli periodici e ad
un’accurata manutenzione per garantire
quei requisiti di sicurezza, efficienza
energetica e tutela dell’ambiente che la
legislazione richiede.
-In questo senso, la normativa
vigente impone che l’installazione
e la manutenzione dell‘apparecchio
e dell’impianto siano eseguite
esclusivamente da tecnici qualificati facenti
capo ad imprese abilitate in possesso
di specifici requisiti tecnico professionali
(D.M. 37/08), ai quali è demandata ogni
responsabilità in merito al rispetto di tutte
le disposizioni legislative e normative
vigenti, siano esse di carattere nazionale
che locale.
