Ok, so I have the old masonry chimney torn down. I now need to run a new stainless liner up. Obviously, the simplest way to install this pipe would be to come directly off the stove and run straight up and out the roof. Not a problem here. The only issue I have is sweeping the chimney. I've noticed from my old masonry one that the shingles were starting to get a bit beat up from standing on the roof so much. Therefore, I'm wondering if I'd want to sweep my new flue from below. I know that this can be done with a T fitting. Come off the stove and extend up close to the ceiling and then turn horizontally into the T. I'm thinking single wall pipe until the T which would be double wall. Are there any issues with the connection between the single wall and double wall? Appearance wise, I'm not sure if I care for the look of the T and elbow being right above the stove. Is there a better way?

How do you guys support the flue pipe when a clearance is still required around it? How far above the roof can the pipe extend unsupported? I havn't measured anything yet, but to get 2' above my ridge, I'll have around 7' of pipe waving in the air.

I have an older home and the stainless flue pipe will be a bit out of place on the exterior. Does anybody make a cover for these pipes? I was thinking that if I could find a artistic copper sleeve that the pipe would look a bit nicer.
 
Im confused with all of it?

You took down all the Masonary chimney? then you would need to run Class A through the roof from the Ceiling up and single or double wall from the stove to the Class A at the Ceiling. NOT A LINER

Using Class A chimney a Support box or a Clamp systems is used at the Ceiling To support the Class A chimney.
the single or double wall is supported by the stove.

How much pipe out of roof?
if you are closer that 10 feet to the RIDGE then you would need to be 2 feet above the ridge. and a minimum of 3 feet of pipe out of the roof.

If you are over 10 feet from the ridge then you need to be 2 feet above anything 10 feet from the pipe.
10 feet straight across to roof then 2 feet above that point
 
Cord, can you post a picture or a drawing of the setup? I can't visualize this either. Is this an exterior chimney?

Ok, I went to the metalbestos web site and got most of my questions answered regarding the installation. Looks like I'm going to need a brace above the roof, which frankly is going to look like poo.

The remaining questions:

Is there a way to skin the chimney? I'd rather not frame out the pipe and cover it with vinyl or faux masonry.

What installation techniques are available so I don't need to walk on my roof every time I sweep the chimney? This is a interior installation through a unoccupied attic. I think this sketch is what begreen was asking for... In the sketch on the right, I don't care for the looks, cost or complexity of the T fitting. I'd rather have the straight pipe on the left. However, once everything is put together, I'm not sure if it could be disassembled for cleaning. I'm also not comfortable with having the sweepings fall into the stove on top of the catalytic combuster.

Forget the tee. Instead factor ina slip joint in the connector pipe. That way you slip it up out ot the way enough to get a brush in and place a plastic bag under to collect the ash
 
Bingo! Right on Elk. Thanks for the post Cord. A picture is worth a thousand words. Go to the Duravent site to see a slip joint connector pipe. It's what we have on our stove.

You will need a brace if you pipe is 5 feet or more out of the roof.
so if your pitch is more that 4/12 then yes you will need one. for you will be about 5 feet out of the roof if you are at the eve and not near the ridge.

Yes you could build a wood Chimney chase or get one of the 30 minute chimney kits. But I think that looks ugly.
