chimney liners

[hangnail]

I just bought a Jotul wood stove and want to put a line in. The dealer where I bought the stove from sells them, but they are very expensive. I think I want a flexable liner, but in reality I dont know what is better, rigid or flexable. Also this chimney is in the center of the house. do I want a insulated liner? I do have a ceremic liner, but do not know the demensions, but it should take a 6'' line which is what i think i need. the lenght will be about 25 feet.

are there any good online stores that sell these. I have found a few, but would like some recommendations

you don't need an insulated liner since your chimney is in the center of the house.

as for flex or rigid, can't help ya out there...maybe it's a matter of preference or dictated by the installation.

I had a wood stove insert put in the fireplace at the end of my house. They used a flex liner. Believe me, the install is easy with a flex; it will get through the throat of your fire box easier. As for price, all metals have gone cuchoo. And I would bet that stainless is at the top of the list. However, have you ever seen what happens when someone goes with galvanized on their chimney cap? It bleeds rust all over the roof. Looks like crap! Bottom line: you get what you pay for.

Look up in the chimney and see if it goes straight up, If Not you definatly need a flex liner. 25' of 6" can be found on ebay for a pretty good deal. I did 25' of 8" and it was $800.00, I was gonna do 6" but my chimney sweep guy talked me out of it. If your gonna do flex and put it in your self....Heres a tip, get some of the small C-clamp looking ceiling hangers (usually used in steel buildings to fasten things to the ceiling) Go up and drop a 30' rope down the chimney, fasten the rope with said clamps and pull the liner UP from the bottom instead of trying to feed it down from the top. pull it up high enough then have 2 buddys stick the stove in place and lower it back onto the stove. thats how I did it and it worked perfect..If you can't find the Lil clamps let me know and I'll send you some.

I have brick chimney in center of house. When I got new oil furnace HVAC man put 5" stainless liner in chimney. Two years later I put woodburner down basement next to furnace,HVAC man had enough room to run a 6" stainless flex liner for it. Everything went well with this setup. Only prob is I get alot of cresote buildup where stainless leaves brick. It must cool down too much.:greenchainsaw:

 

[Blowncrewcab]

Yeah, the only place I get any build up is where the liner tube sticks out of the chimney, about 3" right at the top. when it gets enough build up it'll cut down the flow pretty well. when theres no build up my stove sounds like a jet motor when I open the door, that 8" pipe can flow allot.

Why is everyone putting steel liners inside masonry chimneys that have ceramic linings???

because if you install an insert type fireplace, it's a requirement.

hmm I know that my Dare IV insert does not have a liner... nor does it have any way to connect a liner to it... and the sweeps over the years said nothing about it.. the chimney is lined with flue liner... the only complaint is that its kinda small and we have put A LOT of wood through it

My house was built in 1920. It had only a brick chimney with no liner at all. The oil furnace needed a smaller flue,its more efficient than the old one and stack temp wasnt high enough to heat brick chimney and condensate,nasty black water, would run all over floor after furnace ran.

What do you mean kinda small, liner or stove?

 

[Jkebxjunke]

small logs but then I believe it was put in 1979.....

I'd say insulate, even in an inside chimney.

he needs to check with his local codes. the reason i said he didn't need to was because i installed a new boiler for my hot water heat. the boilervents thru the chimney, which is a double flue: one for the boiler and one for the fireplace. both are clay tile. i asked the town if i needed to run a liner for the new installation and was told i didn't have to since the chimney was in the center of the house...as long as the clay tiles were in tact and not falling apart.

their reasoning was that a chimney in the center of the house is always warm, where versus a chimney on an outside wall would be cold, having an affect on the drafting ability of the chimney. you get less draw on an outside wall chimney than you would on one located in the center of the house.

When going to the trouble to install a liner, the cost of insulating shouldn't be cost prohibitive. It will draft better (as discussed) and add another layer of insurance incase your flue tile and mortar are not in perfect condition.

Of course this is just my opinion, which is a little more cautious since our fire !

My flex stainless Pipe is wrapped in ceramic inslation then covered with a stainless wire mesh that prevents tearing the insulation during installation. IIRC it was only $100-$200 more.

ok, bringing this back up since I am getting readu to go ahead a purchase here soon. I got up on my roof, reminded that I am in desparite need of a new roof :censored: and checked out the chimney. good news is it looks good, has a newer dual cap on top of 2 11 x 7 liners. One is oil, the other for the fireplace soon to be a stove once connected.

Has anyone used any of the online vendors for the liners?
am I better off with 2 seperate caps? How high above the chimney should the cerimic be, mine is only a few inces.


do you have pics of those clips? I am sure I can find them, I am just not sure what they look like

 

[A. Stanton]

Hangnail,

I would advise you to get rid of those dual caps, and use one to cover both. I bought one that covers my 3 flues and have been very happy with it. It is stainless and the company had it powder-coated brown for me. I just glued it down with construction adhesive. Their number is 800-819-2731 and they are out of NC. They recommend that the cap be 5" above the flues. Give em a call and they will tell you what model you need. Mine cost about $325 before the the powder coating. I would post a pic, but it is now dark outside.
