Our new Vaillant boiler whines/whistles very loudly when switched on ?

Our new Vaillant boiler whines /whistles very loudly when it is first switched on for about 5 minutes. Is this normal ? It has been installed for two weeks. The model is VUecoTECplus418.

not normal, sounds like a problem with the flue / air intake system. get your installer back.
