woodstove liner insulation


I am putting an insert into my fireplace with a masonry chimney. It is a 1 story ranch in Albany, NY and the chimney is approx 18'.
I purchased the flexible stainless liner, have had the chimney swept and am now ready to install the 6" flex liner into the 9x18 clay flue.

The store that I purchased from told me to stuff fiberglass insullation around the liner at the top of chimney and damper to create a dead air zone. This didn't sound right since fiberglass is not high temp rated, but they claim to do all of their installs this way.

Do I need to insullate a short run like this?
What should I use?
The chimney is all granite block and mortar.

liner instulation

yes I read your article on liner instulation do not use what they told you you can use heat resistant insulation you can purchase at a home depot or chimney store you need to wrap insulation around the liner spay liner down with an adhesive so insulation will stick then get wire to wrap around insulation to keep in place if you have any other questions please ask
