I have installed so many liners in existing chimneys that should have been done when newer furnaces were installed . Lower temps in the over sized clay liners are moisture machines that destroy the liners in short order. My own chimney was outside the structure of the house all the way up so I filled the cavity around the flex with perlite as it has a slight insulating factor.
Yep. I have heard of people actually filling them with cement top to bottom in a wood burning application as well. I choose to not fill around it. My age is a factor in that choice, because I am leaving this place to my nephew. That way he has more options for the future. Thanks for the comment. I will consider the perlite approach.
Thank you for the great support on this video. You people are just awesome. Thanks also to cousin John and my buddy Trevor for the great help they provided. You need help on a project like this if your doing it yourself. Tell your friends about the channel. Thanks again.
Hello Im getting ready to do mine , how were you able to make that bend out the chimney at the bottom?? I'm using 4 inch to but I think I need a tee { tee snout} . That liner can bend that much???
I have a 10” breakout hole that was needed when I was burning wood in the old furnace. What size is your entry hole? We were able to bend it and slide it thru. It wasn’t real easy, but doable. Good luck my friend and thanks for the support and comment.
In addition, I really wanted no 90 degree turn, and for the pipe to start at the furnace and run continuously to the top of the chimney if that makes sense?
That all depends on the condition of your chimney flue. I would recommend that if you are not qualified or able to inspect it, that you hire someone who is. I HAD to put in the liner because my tile liner in my chimney WAS comprised. Please check it out as chimney fires are always possible. Hope this helps. Thanks for the comment.
It is kind of like an accordion, it stretches out. Just make sure you have the right length for your application and stretch it out as needed. Try to get it to run from your furnace to the top of the roof in one piece. Good luck.
@@jsbomze it is a 140,000 BTU gas furnace, not a boiler. I have an outside wood stove that provides heat as well through a heat exchanger. It is a wood master 5500 and takes 193 gallons of water. No boiler in the house though. Hope this clears it up for you.
@@jsbomze sorry for the confusion. You are right, I did inadvertently call it a boiler. You are very observant. However, it’s just a normal everyday gas furnace. I hope this clears it up for you and anyone else who heard me say that as well. Thanks for the comment. As usual, you all keep me honest. My mistake. Thanks again.

@@AJCurtis Thanks for the reply ,I have about a 5 inch hole dont think i can do it like you did .Going to need a tee. GOOD VIDEO
@@garymonsarratt6048 Thanks my friend. Yeah, 5 inch would be a real bear. I think you hit it with the tee. Good luck.
what will happen if we use wood stove insert with out using / installing the flexible liner in the chimney? thanks

Do you stretch the flex pipe apart or leave it pushed together
It is kind of like an accordion, it stretches out. Just make sure you have the right length for your application and stretch it out as needed. Try to get it to run from your furnace to the top of the roof in one piece. Good luck.
Where is the draft damper for that boiler?
I
Furnace manufacturer said it’s internal, under appliance connector. Thanks for the comment.
Im no rocket scientist but that looks like a boiler not a furnace

At around 24:59 you call it a boiler and i dont see any ductwork attachments only pipes and expansion tanks
