Choosing a stove pipe kit?

[DPurvis]

Having a bit of trouble picking out the items for my stove pipe/chimney. Hoping for some help here. My installation will be a straight up through the roof assembly. I have 8 foot main living space ceilings, approximately 3 ft of attic space to pass through, and a 4/12 roof pitch. Looking to install double wall stove pipe up to the ceiling, and triple wall class A through the attic and out. I would like to stick to a single manufacturer if possible. Looking at some of the DuraVent stuff on the HD website and I came across 2 different "Through the Ceiling" kits. I guess I am not sure what all the components do, but one of the kits comes with 4 feet of triple wall pipe and is $50 cheaper(Listed for mobile home use)

My questions are:

Can I use the "mobile home" kit on a normal stick built house with 24" center roof joists?

If I went with the "mobile home" kit, am I missing necessary pieces to put together the install?

The "mobile home" kit (which includes the triple wall pipe) seems to good to be true...what gives? Is it a pricing error? Pretty sure I saw this same kit on another site for over $500.

How about this? What am I missing? I feel like there should be more pieces involved. The black double wall stove pipe is telescoping. Extends to 68" By my math I only need 66" to get to the ceiling. Is that cutting it too close? I have 8' of triple wall class A pipe. That is enough to get through the attic area plus 5' extending out of the roof. Is taller better? I could spend an extra $25 and get an extra foot of triple wall if needed.

That is a bit more tailored to your needs. There is no need for a cathedral ceiling kit in your case. Don't forget a cap.

What about a storm collar? I still feel like I am missing a few parts. Does anyone by chance have a drawing that details the parts of a straight through the roof assembly?

 

[DPurvis]

Found several very useful diagrams via some google searching. Think I answered my own questions. It looks as if the only part I am missing is the storm collar. I did think of another question though:

• Will the ceiling support kit trim work with the double wall stove pipe I have selected? Not sure if they design different systems for single wall vs double wall.
• Also, does it look like I have selected the right flashing? It says "6 inch flashing" but is that 6 inch triple wall? Want to make sure it will fit.

Yes it will work with what you have there. All the components are for double wall accept where you transition from insulated double wall to, either uninsulated double wall or single wall inside the room. They make a couple different types of flashing depending on the pitch of your roof. Just make sure it matches what you have, and yes you need a storm collar and don't forget to caulk around it.

It's easier to see your list on the computer today, yesterday I was trying to read it on the phone. Yes, a storm collars is important. Check to see if the storm collar comes with the flashing. It should. Also be sure the roof flashing cone is of the right pitch for your roof.

Lowes provides sketchy information. Stove pipe companies have good installation manuals. Some even have parts ordering guides. Go to the mfg. website for detailed info. You can find the installation guide, installation manual and the Supervent product catalog here:

Yes, the ceiling support will accommodate either single wall or double wall. There may be an adapter needed for double wall.

Looking at your setup I am concerned there isn't enough chimney + pipe for good draft. Most stoves are going to want 15ft or more total flue. I see only 8 ft of chimney and one section (length?) of stove pipe. If 3 ft in the attic then only 5 ft will go through the roof. Will that be enough to have the top of the chimney 2 ft higher than roof that is ten feet away?

Mine was about like this when I first installed it. I had about 12 ft. It met the requirements of being 2 ft higher than roof 10 ft away but didn't Draft as good as I wanted. I added a 2 ft section and now I have no issues. Hard to believe a couple feet makes that big a difference but it does

DPurvis, that ceiling support and stove pipe adapter will drop into the room about 8" or so.
You might try a shorter piece of double wall tele, with a straight section of 2x wall to make your stove pipe work. The tele pipe is really nice and should come with a finishing band.
The attic insulation shield is about a foot tall (if memory serves) from the nailing flange to the top, so you should be good there.
The NC30 flue height is measured (per the manual) from the floor, so add that to your total for flue height but also be aware of what begreen said about the 10-3-2 rule.
Unless that flashing comes with the storm collar, you'll need to order that as well.
Just an FYI, I bought virtually the same setup.

ETA: Check prices at Menard's. I think they're a little less than Lowes.

Thanks for all the advice. I have gone ahead and ordered the parts for the chimney/flue. I did end up going with Menards since the overall cost ended up less. I was able to pick up everything except for the flashing and storm collar. Menards only sells the galvanized and galvalum stuff. I found a source that sells them in stainless steel, so I will pick those up locally.

Overall flue length will be around 15.5' in length measured from the base of the woodstove. (Englander requires 15' so I should be okay) Chimney will exit roof approximately 6' on a horizontal plane from the peak of my roof. By my current estimate, my chimney will rise 22" above the peak of my roof. Hoping that this is close enough to the recommended 24" to give a good draft. If I have any trouble during the test fires then I will add a couple of feet to the length.

Sounds good. Take lots of pictures along the way and post them here so that we can follow your progress.
