Question
I have a timberline insert in my fireplace. It was installed in the early 80's and never had anything from the smoke outlet of the insert into the flue. I have had two flue fires 1 year apart. I put both out quickly so no damage to the clay liner. I have a round stainless duraflex liner I plan to install directly to the insert but I am concerned about existing tar creosote in the flue. Can I install the liner and be safe or does the creosote need to be removed first. If a liner is installed and sealed at the top of the flue can there still be a risk of fire outside of the liner. I am on a tight budget and if I have to spend the money to have the tar like creosote chemically removed then there is no need for a liner. I will just need to run a pipe from the top of the insert through the damper and into the opening of the clay flue. I really want to put the metal liner in and fire this unit up but also want it safe.

Thanks in advance for any info you can give or other ideas,

Loren

Answer
Hello Loren, After 2 chimney fires you should have the flue cleaned and video scanned to be sure the chimney clay liner is not damaged, then install the liner all the way to the top (it should be insulated also). I know money is tight right now but do not take short cuts to save money it might cost you more in the long run, including lose of life.
