I have a Broan 659 heater/fan/light for my bathroom that is ready to install. It was about the only combo unit I could find for this size hole, which is why I bought it. You can see a copy of the instillation manual here
I got out the directions and discovered that I'm supposed to mount it using adjustable mounting brackets to fasten the unit to the joists.
The space over the bathroom is unfinished attic with blown in insulation accessed through small panel in a closet ceiling. I really
don't want to go up there! Is there any other way I can safely install this combo unit? And is it safe to cover this unit with insulation after it's installed?
Fingers crossed there is another way to do this...
