HEATSHIELD CERFRACTORY FLUE SEALANT MUST BE INSTALLED WITH CECURE SLEEVE IN A MASONRY CHIMNEY TO MEET THE REQUIREMENTS OF UL 1777 WHERE THERE IS A MINIMUM CLEARANCE TO COMBUSTIBLES OF 0 (ZERO) INCHES AIR SPACE BETWEEN COMBUSTIBLE MATERIALS AND THE CHIMNEY EXTERIOR.
WHEN HEATSHIELD CERFRACTORY FLUE SEALANT IS USED WITHOUT CECURE SLEEVE, THIS PRODUCT DOES NOT PROVIDE THE THERMAL PROTECTION OF A CHIMNEY LINER AND IS NOT INTENDED TO BE INSTALLED AS A CHIMNEY LINER. HEATSHIELD’S INTENDED USE WITHOUT CECURE SLEEVE IS SOLELY TO REPAIR AND RESTORE THE INTEGRITY OF AN EXISTING AND STRUCTURALLY SOUND, MASONRY CHIMNEY’S ABILITY TO CONTAIN AND CONVEY THE PRODUCTS OF COMBUSTION TO THE OUTSIDE.
HeatShield’s hybrid “Cerfractory” technology combines the strength of a high fired ceramic with the heat resistance of high temperature refractory cements. HeatShield Cerfractory Flue Sealant, when used with CeCure Sleeve, is tested and listed to UL 1777- Standard for Chimney Liners by Warnock Hersey. HeatShield has been tested to ASTM C199 Standard Pier Test for Refractory Mortars and is rated “Super-Duty”. It exceeds both IRC and NFPA code requirements which specify medium-duty.
It can be used to reline masonry chimneys with the addition of the CeCure Sleeve, provided the HeatShield Cerfractory Flue Sealant mix plus the CeCure Sleeve achieve a total minimum, ½ inch lining material thickness. In suitable masonry chimneys, HeatShield Cerfractory Flue Sealant may also be used to repair missing or defective mortar joints, or it can be “slip cast” over the entire surface at an average thickness of 3/16 inch (1/8” min.).
HeatShield Cerfractory Flue Sealant with CeCure Sleeve is considered an “all fuel” chimney liner. For use only with residential chimneys that service Category I gas-fired (natural gas or propane), Type L vented oil-fired and solid–fuel-fired appliances.
