Hello, I have this older wood stove I've been using for years, it was my late grandfather and I'm guessings it's from the '70s. It's not perfect, it has seam cracks and the inner bricks are starting to break. I've included some pics. My problem is every time I get a hot fire roaring I start to get a wood smell, it's not smoke but it smells like hot wood if that makes sense. Sometimes it bothers my allergies. I have multiple carbon monoxide detectors around the house that have peak-level options. I've never once had them show anything nor have they ever gone off. I can't figure out what that smell is and where it's coming from. Could it be a small amount of smoke or fumes leaking from the seams? I do notice once in a while my stove can back puff smoke, but it's not too often. Thanks.
