Vent fitting question.

[Jason845845]

I installed my wall thimble over the summer at a height specific to my stove. Next summer I will be upgrading to a new stove with a new venting height and I'd rather not move the thimble. Provided whatever stove I buy allows for direct venting, I would like to do the following to get from the lower exhaust on the new stove to meet up with the thimble (corner install):

stove adaptor, into a 45, the back to back 90's that I can swivel or roll to meet up with the thimble, straight out the wall, into a jet termination.

This would give me a EVL of 15, however, I just think that the flow may be bad with back to back to back fittings. Any suggestions?

You could just build a raised platform for the new stove..

That is option #2 and probably what I will go with. Thanks

I did pretty much that setup in changing stoves. I have a T w/cleanout that goes directly to a 90 w/swivel, then 2' of horizontal to the termination. Had a power failure today and got a couple of burps of smoke, but the rest vented fine. Next summer I will try to find some long-legged support T's (1' is too short, 2' too lonf for pipe)as I would really like a little more elevation to the termination, but for now it seems to be okay.

Hmm, now I see you are doing back to back 90's, so not the same - 1 more 90 than I have.
