Do i need to use the double wall stove pipe in my attic? I know i have to use it through the ceiling and roof and 36" up outside roof right? But do i have to have it all the way through the attic? Also i have a fake stone chimney in my living room if i run the pipe through it does it have to be the double lines as well. I just want to be safe and also get great performance.
Someone also told me no bends in th pipe but i see many installations with slight bends. Any thoughts? image.jpg
 
No you don't have to use double wall stove pipe in your attic.
You have to use Class A chimney from the first ceiling (or wall) penetration ALL the way to the cap.
What you run in the faux-stone chase will depend on the unit you install.
Many units installed in this manner have their own specified type & brand of venting.
What unit is in the construction?
Elbows & offsets are allowed, but not greater than a 30 degree in the Class A.

Pretty sure you need the double wall pipe in the attic if you do not have an existing masonry chimney there already. You will also need specific materials to keep the attic insulation from contacting the pipe.

There was another tread recently which was. Dry similar to your line of questioning. One of the members runs a chimney supply business and gave an excellent response about exactly what was needed for the job. Search around to see if you can come across it.

The fake chimney may or may not be useable. If it is truly fake, then it probably was not built to code for use with a wood burner. I would think in this case you would need the double walled pipe. You can get away with just a liner in an existing masonry chimney was designed for wood burning. Doesn't sound like that is the case for you though.

Maybe give a chimney supply place a call and get their input.
 
What is confusing is the term double-wall. Forget that. What you need to do is to switch from connector pipe to high temperature chimney pipe (class A) the moment the room envelope is penetrated by the stove flue system. It's not clear what you are trying to accomplish with the existing setup. Could you clarify?
 
If the unit you show in the photo is a wood burning insert or if you plan to replace whatever you currently have with a wood burning insert you are going to have to get some sort of hearth extension for in front of the unit. To my knowledge, most inserts require 16" of non-combustible hearth in front of the insert.
 
Thanks guys. Let me clarify whats in the (sideways) picture lol it is real stone however just for looks. The unit in there is electric. I want to get rid of it and put a wood stove like the Lopi Liberty or similar in front of it. I would extend the stone to the floor to do this and close the tv hole, which is finished. I would then expand the old electric insert hole and finish with stone so i could "partially" recess the wood stove. I wanted to run pipe up through the fake chimney, through attic, through roof. Room is 18', attic 8'. Thanks and hope this clarifies.
 
well you need to follow the clearance requirements very carefully for the stove realizing that that framed wall with stone directly on it is not a noncombustible wall. And you cant run stove pipe single or double wall anywhere inside that chase it needs to be class a insulated chimney from the point that it enters the chase until the chimney terminates above the roof.

Thats what i thought. So as long as i get the right pipe i should be able to run it up there?
 
You need to stop calling it pipe it is scaring us making us think you are going to run double wall stove pipe in there. What you need is insulated chimney not pipe ok I know I might be getting to picky and I am sorry but I just want to make sure there is no confusion.

Please post a diagram that details out the plan. Specify what you mean by pipe. Doing this wrong could be unsafe.
 
When i said "double wall pipe" i was referring to class a insulated chimney, such as the ICC Excel or similar products. My terminology was wrong. I am new to wood stoves and have not purchased anything yet. Im not ignorant to the safety aspects and i wont do anything unless it is very safe and to code where required trust me.

ok good I just wanted to make sure I kind of assumed that is what you meant but it is dangerous to assume things like that
 
So i know there have been several threads on the topic but time changes things so i thought i might ask again....i am seriously considering the ICC Excel insulated chimney. From experience, where would be the best place to get a deal on this? I know most places offer free shipping which eliminates location issues really. I am looking at the 6".
 
Of course i anyone believes there is a comparable product for less i would entertain that however if the price difference is only slight i would prefer to stay with it as it seems to be really good from reviews. I will be needing roughly 28ft plus a rain cap etc...going through roof and ceiling.
 
I think you will find Excel pipe costing about 50% higher than other Class A pipe.

Last time I sold it (2011) 6" ICC Excel went for about $55 USD per foot...

Thats what i have found also. How about this selkirk? Any lower cost alternatives that may provide close to similar performance?
 
Do you have a Menards around you? Usually they everthing needed for your install. I just don't remember if they are that far south.
 
They have one in indiana, and we go there frequently. We have home depot and lowes here. I thought about getting stuff online, thought it may be cheaper. I went to champions site and they have a config thing where you plug in numbers and they sell you a "chimney system" was about $1300. For 11ft of through attic class a chimney with cap and all needed hardware. I figured if i got everything from an installer and let them do it it would be significantly higher. Who knows.
 
I want to get good chimney but if the cost difference is significant i dont need the "mercedes" chimney.
 
Lowes has supervent by selkirk, you prolly checked that already. I like it, just have to open boxes and check for dings in the class A. They may discount the dinged ones for you too! I was right around $700 for 14' and all i needed
 
DuraTech class A is fine.
