Chimney and stove pipe systems
The DVL pages state the point of double wall: clearance down from 18 inches to 6 inches, and 8 to ceilings.
Each part fits one system: DVL, DuraBlack, DuraPlus, DuraTech or PelletVent. Read the model name before you order, as a good price on the wrong system is no bargain.
