Stove installation

I'm installing a Wonderwood stove rather than the add on furnace. Putting the stove in the basement and venting out of a window with double wall stove pipe into a double wall insulated chimney. I had a 3/16 metal plate made to replace the window. I read where using more than 2 90's to connect to the chimney is not recommended, it will take 3 to do this since the stove exhaust is on the rear. 2 questions, can I get by ok using 3 90's to connect to my chimney and how much clearance over the eaves do I need? I was thinking 5 foot above the eave. Thanks, Erik

Don't see a problem with 3 90's.
2 feet above any roof within 10 feet is the recommended height.

Richard is correct on the clearance, you want to have the chimney 2' taller than any obstacle within 10 feet.

I would go a little taller to compensate for the extra elbow. The taller the chimney the better it will draw.

I don't see a problem with using 3 90's however you need to extend the pipe a minimum of 2' above the peak of the roof or you will likely get downdraft from time to time.

Best to check with/inform your insurance company, you will have to anyway to keep your coverage and they will give you all the install criteria.

You need to consider that any horizontal pipe is going to affect negatively the draw of the flue gases. How much? suppose it depends on the length of the horiz. section. It will also be more difficult to make the initial fire, but I've found that burning several sheets of paper at first will start the drawing effect. Another factor---There will be some build-up of ash in the horiz. portion of the pipe, which essentially reduces the size of the flue.

You might think about turning the furnace or re-routing the pipe to substitute a couple 45's. You'll always be stuck with at least one 90 but the rest are negotiable.

If you are using double wall insulated chimney it could be Selkirk Metalbestos. If it is you can get all kinds of fittings to set up your chimney. You can get an anchor plate to use as a starting point a TEE to put on top of that and then put your chimney on top of that. You could put another piece of insulated pipe horizontally thru the window.
Take a look at the catalog.

Had a similar problem and went with two 45's. Not as easy going thru a wall or window at a 45 rather than a 90 degree angle, but it will draw much better so worth the extra effort.

I wasn't using my thinker, any reason I can't use 2 t's with clean outs and one 45? Should draw much better.

The real question is, how are you going to clean it? I have 2 different chimneys that are straight up, easy to clean with a plastic brush. You may have to take yours all apart, maybe you could pull a brush through with a rope.
