Picked up a Hampton Regency insert and cant wait to get it going. From all I read here I want to have liner insulated. 20 foot exterior chimney and when I measured the clay tiles it appears they are about 8.5 x 13. outside diameter. It look like the inside diameter was maybe 7 inches best. My ladder was a little short and I was reaching to get these measurements. I don't think a six inch liner and insulation wrap will make it down. Whats my best economical option to accomplish this. Ovalized or preinsulated or another avenue perhaps ?? New to burning and want it done right. What do you all think.
 
Duraliner if it is straight or ovalized flex if it is not. The other option is to have the old liners broken out

So if I understand Duraliner is preinsulated and the ovalized flex needs to be wrapped. Didn't see that on the website and also didn't see the O.D. of the Duraliner. Is/does Duraliner have any flex properties to it as it will need to pass through the damper area (which needs to be removed) and then connected to the insert. Honestly I have to measure to see how har back the insert will be when installed but I think its pretty dang straight. I love this crap and hate it at the same time not having done it before. Thx
 
Another question comes to mind. Can I downsize to 5.5 liner with a 20 foot chimney run?? Does it alter performance as I will be using this insert every day to heat

Yes it absolutely alters the performance you should call regency and ask if you can use a 5.5 at that height. I have never used duraliner and don't plan on it so i cant give you input on how it works but many here seem to like it. And yes they have flex sections. But your chimney has to be really straight a little offset in the liners of bend can cause problems with rigid liners
 
The preferred solution is to have the tiles broken out. It's not hard or expensive. You'll be glad you did it right once it's done.

Well it can be very hard and it can get quite expensive depending on the situation. can we see some pics and get some more info? Breaking out in a fireplace is usually not the preferred method there are lots of complications that can come up. But some times it is still the right option
