I had to shut down my stove last night due to a too strong smoke smell. I posted about getting my Piping right up to the top instead of the 5 feet the y give you. I will be doing that anyway. BUT I thought as I was down I would clean and pull the stove to inspect behind. i found the Combustion Motor was "Hanging" by a thread. Two of the three bolts were almost out and the third half loose. This was a replacement put in by the Dealer on tuesday as the other had Died. I had noticed a tapping coming from the stove sometime around the increase in smoke fumes. Is this likely to have been culprit. I suppose I will find out when I fire it up, but I'm off to work now and cant till this evening.
