Well, wouldn't be a burning season without an issue. Have the stove under a full load tonight. She is running like a charm cruising at 600 or so, but when I just went downstairs to check on the stove before going to bed I could hear a familiar whistling sound. The joint on the back of the stove between the side panel and rear of the stove is sucking air. This is the problem I had the stove shop come out to look at last year that led to my many documented problems at the end of last year. For now, my plan is to let the stove go out tomorrow and to patch the joint with some stove cement. Yes, a short term solution, but I just cannot face having to bring someone in again to tear the whole stove down. Hopefully this is not an indication of how this winter is going to be.
