ᐅ Distance between exhaust vent and planned carport/roof structure

Hello,
we have a central ventilation system with heat recovery from Pluggit Avent installed in our newly built single-family house. Outdoor air is drawn in sideways through a double grille on the exterior wall, and the exhaust air is directed away from the building.
The volume flow rate is 140 m³/h (82.4 cfm).

We are now planning a carport attached to the exterior wall:
- How far should the carport roof be at minimum from the exhaust air outlet (the height of the exhaust air outlet is at the same level as the carport roof) to avoid impairing the function of the Pluggit system?
- Are there any other considerations we should keep in mind?

Thank you for your advice.

I think the plugit doesn’t really care. However, mold and algae could develop on the carport.
