We had our avalon astoria pellet stove installed in august of this year.Last night and tonight it got cold enough for our first burn.The stove is vented direct out of the sidewall of our house,we have noticed a slight smell of wood smoke.I have checked all of the pipe seals and door gaskets,no leaks there.The smoke smell seems to be coming out of the front blower motor.Is this normal?Thanks for any info.coobie
