Liner questions and recommendations

[john84]

I currently have a flex liner installed in my exterior chimney approximately 25-30 feet. Due to being a newbie when it was installed a few years ago I do not know the brand or specs on it. I am in the process of buying a new stove to replace my Encore,(f55 or quad explorer) and want to do this 100% this time around. So for my questions should I buy insulation wrap for my current liner? Install roxul to the top plate and just above my block off plate? Or bite the bullet and buy a new liner? Any opinions would be appreciated.

What size is the liner? What size is your flue?

6 inch liner. Honestly I will have to measure the size of the flue. I believe it's big enough for an insulated liner. The house is only 5 years old so it should all be in good condition.

I would look to see if you've have room to fit Insulation. If you do, pull it out and insulate it then throw bit back down I don't be see a reason why to not to reuse it

I was hoping to be able to do that. Any recommendations on a quality insulation? Is it recommended to bring the insulation all the way to the block off plate?

Thanks

Does anyone have experience with this particular wrap? Is there any reason not to use this?

Thanks

Looks like they have what you need. Double check the masonry chimney throat size to be sure you have at least 8+" clear for the insulated 6" liner.

I plan to remove my block off plate this weekend to make sure everything looks like it will work. Is it recommended to also insulate just above the block off?

 

[john84]

I obviously have to pull my liner to insulate, like I said before I do not know the brand, thickness, etc of the liner....

Is there anything I should look for besides the obvious like splits in it?
