The black pipe between a wood stove and the chimney is easy to overlook. It's called the connector pipe—or “stove pipe”—and its job is to carry exhaust from the stove to the chimney. It isn't the chimney itself.
We just published a guide to single-wall versus double-wall stove pipe. Single-wall is one layer of steel: lower upfront cost and more heat released into the room, but it sheds heat from the smoke and can corrode from the inside. Double-wall has an inner liner and an air gap that keep more heat in the venting path. A listed double-wall connector may be allowed closer to a wall, but only at the clearance printed on that exact pipe's label.
Here's the important part: switching pipe types does not automatically change how close your stove can sit to a wall. The stove's own manual still applies. And neither kind of connector pipe belongs inside a wall, ceiling, or attic; that's where the proper chimney system takes over.
If you're replacing rusty pipe or planning a stove layout, the article walks through what to compare and why the whole installation matters. We check the connector and clearances and show you documented findings—not a one-size-fits-all answer.
