Insulation shields and air vent

[wstan]

Hey guys,

I'm new to the stove world and will be installing my first wood stove in the next couple of weeks. Couple of quick things I can't seem to find the answer to.

1. I have a drywall ceiling in my living room, but then a foot or two above that is a second set of ceiling joists with a plaster ceiling (old house), then rafters. The insulation is laying on the second plaster ceiling. I can't fit an attic insulation shield anywhere in this. Can I just build plywood enclosure for the entire thing (support system to roof) making sure I have a 2" clearance to chimney?

2. There is an A/C vent right where I want to build a hearth pad. My stove only requires ember protection, no R factor, and 8" clearance to combustibles on back side. Vent would be going in right behind the stove a few inches. With it being a metal vent cover, is that still ok to cut and put vent through the hearth pad even if it's inside the 8" clearance?

Forgive me if any of this sounds ignorant. Any help is appreciated. Thanks!

It's probably ok. Is the vent only for AC or also for heat in the winter?

It's for heat and AC both, but functionality of the vent is not the biggest concern. Just don't want to close it off completely.

A concern might be if there was an outside air port on the back of the stove just a few inches away from the vent, but only if there was a risk of it pressurizing the intake for the stove. Sounds like that may not be the case here.

There is an option for an air intake, but haven't had plans on putting that in. I'll look to see if that would be an issue, but doubt it.

If concerned, a deflector could be put on it that points the air to the wall.

Didn't think about that, I appreciate the input.
