Should i just run a 6" liner with no insulation or should i get a 4.5x8.5 oval liner and run insulation or do the mix insulation.

I will know tonight but it looks like i will need 25ft. Which with cap and all and no insulation on rockford chimney it is going to cost 1200.00
 
I had to put up a separate chimney for a wood stove I had. went with Dura-vent triple wall class A. They have a modified name but it is still dura-??? but a 3' piece is around $80+/-. I don't think the brackets would be that expensive. Their 3x comes insulated already. If you can do that you might save some.
 
This chimney is in the center of the house it feeds 2 fire places one indoor gill and then the boiler room. I think i am going to run a 6" pipe and call it close enough. I will run 7" out of the boiler over to the chimney which will be a 4ft run i will wrap that pipe and at the wall i will turn it to 6" before the T. I don't think it will be a big issue with a 130k BTU to run on a 6" exhaust.
