  8. The National Fire Protection Association standard 211 (NFPA 211) also requires all liners to be insulated around the     outside. Insulating the liner prevents heat transfer , from a chimney, to the outer walls of the chimney. Additionally, insulating the liner contains the flue temperature within the liner thus producing a hotter flue temperature which naturally increases the draft of the venting system.
