Pellet stove liner recommendations?

Hey All,
I need to redo the liner for my 1200i insert, any recommendations on who to order the parts from? I tried 1 online dealer and when I called with questions they were absolutely clueless....
I basically need a rain cap that will fit on top of chimney, and 18' of flex liner. Unfortunately, the Quad exhaust exits straight up and out the back of the stove, I see no way of installing any type of clean out Tee. Currently I just disconnect the flex pipe off the back of the stove and clean it that way.
thanks in advance!
John

Make sure you use 4" liner.

I currently have 3", what are the advantages of 4"?

Oh, and do you need to insulate the flex liner on a pellet stove?

First of all I know the stove manufacturers recommend, some possibly requiring the use of a 4" liner. This is because of the long run and the risk of creosote build up partially or completely blocking the liner.

Insulation is required to maintain the UL listing when connected to a solid burning appliance. It will also help reduce creosote build up.

Thanks. I was always under the impression that creosote wasn't an issue with pellets though.

Thanks for all the input James. I am going to add one of these adapters on the back to go from 3" outlet to 4" and run new 4"flex up the chimney with the proper cap on the roof

Why do you need to redo your liner? If you have flex liner now, how long has it lasted? Thanks.

The liner itself seems to be in good shape, but the original install done incorrectly. Installer only ran about 12' of 3" flex off the back of the stove and up an existing fireplace chimney. Should be 4" and should have a proper cap and top plate.
