I've been shopping around on the internet for a good liner for my chimney for a fireplace insert install. I have a few questions about them before I spend money. One unit that I liked was http://www.chimneylinerinc.com/smooth-liner-kit.php it is a smooth wall liner. I was also looking at this one http://www.woodlanddirect.com/Chimn...mney-Champion-Easy-Flex-Chimney-Liner-Kit-6in it has a standard spiral on the inside. Anyone have experience with these liners? Logic tells me that the smooth one would be better in pulling draft and have less surface for creosote to hold onto. Is there a real need for me to spend the extra money for the smooth wall? Or do you have another suggestion for a better / cheaper option?
Also what should I choose for a top plate the standard sag-free/flat plate or upgrade it to a clay top? The local dealer said they only install the flat ones and never had a problem " the weight of the liner and the caulk hold it firmly in place and seal out water".
I have a 25' (top of clay to bottom of fireplace) straight shot exterior wall brick chimney going to an old Avalon 796 but eventually upgrading to a bigger insert. I plan to insulate the liner and ad a block off plate.
any help or comment would be appreciated
