Fireplace on the terrace and pizza oven, problems with draft?

[Plupp 122206]

Hi, I am planning to build a fireplace and a pizza oven by the terrace, can the pizza oven's chimney be connected to the fireplace, or will that be a problem?

How horizontal can the pipe be?

Why?
I think it looks nicer with a chimney each. Easier to get it right too.

Tipi is even simpler than a fireplace and warms really well for two people sitting in their own chairs in front and sipping rosé on a summer evening
