How much clearance does a stove pipe heat shield save?
Bare single-wall connector pipe needs 18" of clearance to combustible walls and ceilings. With SBI's approved shielding installed, US clearances drop to 6" to side walls and 9" to the ceiling. Other shielding generally gets you to 9" at the wall. That's often the difference between a stove fitting where you want it and having to move it out into the room.
Two rules always apply. First, shielding the pipe never reduces the stove's own clearances, so use whichever number is larger. Second, single-wall pipe can't pass through a wall or ceiling, can't be used outdoors and isn't allowed in mobile homes. Always follow the connector pipe clearances in your stove's installation manual.
Heat shield or double-wall pipe?
Double-wall connector pipe gets to the same 6" clearance without a shield and runs hotter inside, which helps draft and cuts creosote. Shielding is cheaper when you already own single-wall pipe or only one section of the run sits close to the wall. Compare single-wall stove pipe and double-wall connector pipe, or get everything in one box with a wood stove pipe kit.
Protecting the wall behind the stove
A pipe shield only covers the pipe. To cut the stove's clearance to the wall behind it, use a certified wall heat shield. See wood stove heat shields and wall protection and our wall heat shield guide.
