OTHER THAN THOSE SPECIFIED IN THE INSTALLATION INSTRUCTIONS B Creosote and Soot Formation and Need for Removal When wood is burned slowly it produces tar and other organic vapors which combined with expelled moisture forms creosote The creosote vapors condense in the relatively cool chimney flue of a slow burning fire As a result creosote residue accumulates on the flue lining When ignited this makes an extremely hot fire The chimney should be inspected every two 2 months during the heating season to determine if a creosote or soot buildup has occutred If creosote or soot has accumulated it should be removed to reduce the risk of chimney fire C The recommended method of cleaning your Z Flex Liner is with a poly chimney brush approximately 1 8 larger than the diameter of your liner The liner should be brushed until all creosote and soot have been removed D It is recommended to have the chimney lining system checked by a qualified chimney inspector such as a certified chimney sweep at least once annually following the initial installation of the lining system E Any heating appliance connected to the chimney liner must not have a flue outlet size larger than the chimney liner area at its smallest point PARTS COMMON TO Z FLEX LINER SYSTEMS Base Tee Lock N Go Tee Insert Connector Chimney Flashing Z Max Flashing Deluxe Rain Cap Z Max Rain Cap Top Suppott The replacement parts components for the
