Hi,
I'm a long time reader here and certainly have gotten lots of great tips from the hearth community. I've been a wood stove heater most of my life but now in a new home with a fireplace that's a perfect candidate for a Jotul C550 insert. I'm picking it up next weekend and doing the install myself.
The C550 calls for a 6" flue which I have the space in my 23' 8x13 chimney flue pipe, straight up, but I want to use the 1/2" insulation kit with the 316ti liner. They say you must add 1.5" to the liner size for 1/2" insulation. That brings the 6" liner to a 7.5" diameter. Only problem is the I.D. of my 8x13 flue pipe is 7-1/4" and because it's an older chimney there's a little shifting in there.
My question is am I going to be loosing out on efficiency by ovalizing the 6" liner slightly to fit? Or void any warranties? Would it be the same as using a 5.5" liner that I don't have to ovalize? Can a 5.5" liner be used on an insert that's suppose to be a 6"?
I have read about the poured in vermiculite but I don't like it for a few reasons.
Thanks,
JTP
