Thank you!

Very kind of you. Thanks! I encounter the same exact problem here, people just don’t care. I will never install a liner that can be cut off with a razor knife. 🤣 I’ve actually removed a bunch of light wall liners that had already failed after less than ten years. People love them though, that 15lb box you get delivered ups is pretty convenient.

Where in Ohio?

Thanks for your support! I will try to put out some videos on mortar in the future.

Same here, peace of mind. I use the mflex stuff because that’s what they send me most of the time.

@@chadvaillancourt I will have to check that silicone out! Thank You.

That’s exactly how I do it. Although I don’t like corrugated liners at all.

This is the crossover liner I guess so it’s a little heavier than the normal liner. I only have a 10’ run down a straight chimney to a free standing wood stove. I just smashed the existing flue tiles so I’m hoping it goes smoothly.

Oh good, crossover is a really good product. 10’ is about as short as they get. Should be very easy.

It’s only like 2 square inches when ovalized slightly. This is well within what the manufacturer would allow me to do. At the end of the day, sometimes you do the best the situation will allow for. I couldn’t fit a 7” round here otherwise I would have installed one. Ovalizing 1” is perfectly acceptable.

Exactly; most energy efficient boilers require a stainless liner.

Sometimes, but it depends on the manufacturer and how consistent they are, along with how they were installed. They make a 5.5" liner for exactly what you're trying to do.

@@chadvaillancourt okay thanks.

It depends on the quality of liner that was installed. I have personally pulled out corrugated liners that only lasted 8 years and many more that lasted a little longer. Unfortunately this is the type most install because it’s the cheapest and lightest. I do believe that a heavywall liner or light heavywall will last for many years, at least 30 I would think. We’ve yet to see a long enough sample size to determine. Smooth wall liner, if it’s not damaged on the install will probably last for slightly longer that the corrugated. A chimney fire will certainly destroy a cheap liner, maybe it wouldn’t be noticed immediately but after firing over a certain temperature the stainless starts to turn purple and blue in areas, these areas will start to rust through afterwards. I’ve yet to see a heavywall liner fail.

@@chadvaillancourt thanks for your reply. I ordered my liner last fall from Rockford chimney supply. It is a corrugated rectangle liner due to the size of my existing flue. Hopefully those are decent liners… I think I had around $1200-1300 in it and did it myself. Luckily it was fairly easy to install. Just a straight shot down the clay tile flue and into the tee.

It’s kind of steep for corrugated liner but if you did it yourself you definitely saved a lot. It will probably work fine for many years, just be careful while cleaning so you don’t tear it.

@@chadvaillancourt I thought it was kind of steep too. Although it was more of a custom size which I believe is why the steep price. I bought a rig for my cordless drill that has weed eater string with detachable poles that is made for it so I’m hoping no tears happen.

Typically I will use a couple brick when mudding around the snout. Then I parge over them after.

Ok thank you!

use a rotary sweep method with flexible bristles

A chimney needs a clean-out to be code compliant. This is the best way I know how to provide one.

Apparently you didn’t watch with the volume on
