Pre-insulated liner a viable option for limited diameter?

[19glendale]

I'm installing a Century S244 stove in my masonry fireplace which has a 6" connection and the manual calls for a 6" pipe.

My chimney flue is 6.5x10. I don't want to bust out the tile/terra cotta liner.
I had originally intended on a heavy wall 6" pipe with insulation, but that will be too big from what I've been advised on this forum (possibly 7 3/4").

I've also read the 6" pre-insulated is OD 6 5/8".

Will these pre-insulated liners compress just a little bit (1/8") to fit down the chimney with the aid of a pulling cone?

ovalize the heavy wall or remove the tile like i said before. Or call the manufacturer about a 5.5"

How is the ovalizing accomplished? I don't want to remove the tile.

Thanks

You would either order it oval or you would have a sweep with an ovalizer ovalize it for you. I have seen guys smash liners with boards and hammers ect but I would not recommend that.

or you could order an oval preinsulated liner. But if you are ovalizing you need to find out what volume you need. For a 6" stove you need to go up to a 7" liner when ovalizing to maintain the same volume. Only the stove manufacturer can tell you what volume is needed.
