NC-30 basement install questions

[crawfish]

I Want to install an NC-30 in my basement but have a few questions. To comply with clearance issues in my situation I will have to extend my double wall pipe through the wall by adding either a 15 or 30 deg. bend and another 18 or 24 in. section before I get to my stove pipe. I have never had a freestanding stove just my insert upstairs and was wondering if anyone thinks would negatively affect my draft enough to cause problems? And would it be better to use a 15 over a 30 or vice versa? Running out of options and hope this will work!

Why the angle? Is this a clearances issue? Would this be coming off of the short piece off the tee?

Yes begreen because of clearance issues. I have very limited options because of many pipes, wires and the like around perimeter in an 80+ yr. old house. I have been racking my brain for days for options and only about 18-20 inches of foundation above ground. I would prob. be in the house maybe a foot or so and then angle slightly down for at most 2 ft. then short piece of horizontal stove pipe before going 90 deg. onto stove. Low ceiling too only about 74 in. to bottom of floor joist but at least it's open and no ceiling so should heat floors up

A 74" clearance will be below many stoves 84" requirement. It sounds like a ceiling heat shield may be required. Check with Englander on their above the stove clearance requirement. One option for the tee connector would be to put in a 20 or 36" deep basement window well around the tee to drop it lower, then connect with double-wall connector.

Thanks for the heads up on ceiling clearance! Didn't know that. As long as I meet NC-30 stovetop to ceiling clearance requirement should that be ok? Have to check on that. And yes I have a shallow window well already think 18" but could make it deeper if need be I suppose. Thanks begreen!

What will be the distance to the ceiling of the tee connector that comes through the wall?

3" to bottom of joist. Just need 2" for that right?

I have never seen a horizontal pipe to ceiling spec but with my basement install I had a lot more than 3" to joists but when the pipe is hot the joists and floor over it got way to hot for my liking. I made a heat shield over the pipe and elbow from sheet metal and put a blanket of Roxul on top of it. Hung it with metal plumbing pipe hanger strips.

Horizonal section would be Double wall chimney pipe which just needs 2" CTC right? I would run it down to get 18" clearance to ceiling on stove pipe

We need some more learned people's input on this. Rising heat is a whole nother animal from radiated heat sideways.

Good point Brother Bart! Of course I like begreen's idea of a deeper window well. I just went out and checked mine is only 12" deep so just looked on Lowe's and they have one 24" deep which should allow me to get tee down low enough for any clearance issues. I checked with my Homeowners and they say putting galvy sheet metal with a spacer under joist will allow me to have just 9" clearance to ceiling for stove pipe. Think this might just work. Have to get to bed...thanks for the help guys!

Double-wall stove connector pipe needs 9" ceiling clearance and 6" side clearance.

You're welcome. Based on the low ceiling my inclination would be to install a ceiling heat shield regardless, for more peace of mind. To do this, get a sheet of cement board like 1/2" Durock and suspend it with 1" spacers from the ceiling joists, centered on the stove so that if shields from the wall penetration to past the front of the stove. Hang is on 1" non-combustible spacers. A quick way to make the spacers is to snap off 3" wide x 36" strips from the end of the sheet of Durock. Double them up on the joists to make the 1" spacers.
