Liner for a fireplace insert Winter Warm

[tango_1000]

I just got a used Vermont Castings, Winter Warm in great shape.
I'm thinking to "insert" it in my actual fireplace, I have now gas logs I never use.
Would like to ask if someone here can advice me about the liner I need for it.
I have the chimney very tall at about 36 feet.
Do I need to insulate it? it is a brick chimney no very old, maybe 20 years and probably was never used, We moved here 2 years ago.
And the other question...Is the liner have to go all the way up to the top? or I can put lets say a 25 foot inside the chimney...
Any help will be appreciated.
Thanks

yes it needs to be insulated and yes it needs to run to the top. You will regret it if you dont do either one

Welcome to the forum!

Don't forget to install a block-off plate to keep the heat in the house: https://www.hearth.com/talk/wiki/make-a-damper-sealing-block-off-plate/
The Winterwarm will want dry wood with an internal moisture content of less than 20%. Do you already have several cords of dry wood?
The Winterwarm is not that easy to operate. I recommend to search in the forum for experiences from other users.
