   Dave,
   Q. "The kitchen and living area are open to each other, and both are roughly same size (15'x18'). I assume it's fine to have the fresh air at one end and the exhaust (kitchen area) at the other?"

   A. Yes, that's fine -- as long as the exhaust grille is as far as possible from the kitchen range. Under no circumstances should a range hood be connected to an HRV exhaust duct. You don't want your exhaust grille to inadvertently suck in a lot of cooking grease or smoke.

   Q. "Is it fine to have the vents for fresh or exhaust air on the walls and not in the ceiling?"

   A. Yes. High up on the walls is better than low down on the walls.

   Q. "If they have to be in ceiling, they would be in the unconditioned attic space covered in cellulose."

   A. It's possible to route ventilation ducts in an unconditioned attic as you propose, as long as the ducts are buried in deep cellulose. But keeping the ducts inside the home's conditioned space is even better.

   For more information on HRV ducting, including tips on locating registers and grilles on walls, see this article: Installing a Heat-Recovery Ventilator.

   Thanks Martin for the quick reply and article, I missed that one.
   As for distance from the range, is there numbers for this?
   It will an induction stove with hood above, which will be the next problem to solve ( make -up air)
   I BBQ a lot so there shouldn't be a lot of greasy meals cooked inside.

   Dave,
   Q. "As for distance from the range: are there numbers for this?"

   A. I would use common sense. How does a minimum horizontal distance of 6 feet sound to you?
