pipe liner questions

[ledwards]

I am planning on putting a wood stove insert in my masonry fireplace.

I have a chimney with what appears to be a 6.25x6.25 terracotta pipe. Any thoughts on: 1) whether to line the pipe with rigid or flex liner 2) any tips on getting a 6" liner installed without major headaches (snags, etc)?

is it a straight shot... If it is I would reline it with rigid pipe, but if its got any turns I would run flex just for the ease.. rigid on the outside diameter is like 6.048 whereas flex will be closer to 6.375

Just stick a 5.5" flex liner down it.

External chimney or Internal? Height?

Based on the condition of your chimney tiles you might need to think about insulating as well, so that would leave you the 5.5 inch insulated.

It's an external chimney about 15-18ft tall.

I have read mixed reviews about going smaller than a 6 inch liner. Also, even at 5.5, I don't see how I could get insulation in there too.

Thought?

With a chimney under 20' I wouldn't downsize the liner. Mine work fine with 5.5" but both are over twenty-feet tall.

is vermiculite dry poured legal?

That and the 5.5" liner is what I was thinking. Anything larger is going to be a real headache to get down the chimney.

Get a bid for busting out the tiles and you will have plenty of room for an insulated 6" liner.

Has anyone ever priced this? I've often wondered what they charge for doing this...

You could just buy the tools and have your own demolition derby.

Wow, bookmarked that website, all kinds of fun tools. To bad they do not have an image of the tile breaker, sure sounds like fun to stand on the peak with a high power drill with weight on the end, NOT!

Here they are.

If the chimney was 20' or higher, what would be better, an insulated 5.5-inch liner or an uninsulated 6-inch liner?

I assume a cone adapter would be needed to get the pipe down that tight chimney.

In my part of the country breaking out the tiles,ss liner,ther mix insulation installation about $1300.00 for 15' .
