Insul-Liner™ is another “simple solution” from Z-FLEX
®
. The National Fuel 
Gas Code (NFPA 54, ANSI Z223.1) recommends that liners be insulated in 
certain situations. 
A good rule of thumb is to use an insulated liner in exterior chimneys or when 
a brick chimney has no clay liner at all. The insulation will keep the flue gases 
warm to prevent condensation. Also refer to the equipment manufacturer’s 
instructions for their recommendations. 
Insul-Liner™ replaces B-Vent when relining a masonry chimney.
Insul-Liner™ is insulated at the factory and protected with an outer aluminum 
jacket. This eliminates the time needed to insulate on the jobsite and prevents 
damage to the insulation during installation. Simply remove from the box and 
install.
