Stove pipe between furnace and water heater?

[NoPaint]

One way to get the stove pipe from where I want to put a stove and to the port in the chimney is to run between the water heater and the furnace return duct. I don't think this is OK. So my question is - if I use double wall it should be cool enough to run that route - but now I am unsure if it would be ok to have a foot coming out of stove, a 45, 2-3 more feet, and another 45 into the chimney. Too long to maintain a draft? Too long to start a draft? Won't even fire?

5' total. That isn't very much. And only two 45s is perfectly fine.

What are your clearances?

How much rise is there in that 5' that is what matters and what clearances do you have

Yea, the rise HAS to be there or it will be bad.
