I've just bought a house/cabin, but have not moved in yet. The chimney is entirely outdoors and seems tall enough. It also has a chimney cap, et al. But to me it looks like a big culvert pipe, something like what you would see under a driveway. It has been anchored into cement at the bottom and tied to the house with metal strapping leaving a roughly 12" gap between the house and pipe. My realtor says the insurance companies like this type of chimney... I'm just wondering if anyone has seen a chimney like this before?
