Just installed my breckwell 24 insert got it up and running. The fan was making a lot of noise had already oiled it. Since the stove is and older model went a head and got a new one. It appears to be just about as noisey. My question is this normal on this model of stove or did I get faulty new motor. Have a hard time believing it should run this noisey. Any input on this subject would be a great help.
