1- no. no unvented heaters in bedrooms, bathrooms, or any confined space. I don’t like them at all, anywhere, anytime.
2- not less than 6" from the ground. I don’t like them either…lots of heat loss…better options.
3- 2" to 4"
4-F I want to say 8ft is the limit on the studs if they are supporting more than the roof and ceiling, if not i think 10ft…not sure though.
5- looks like the tyvek is over the concrete which will allow moisture to infiltrate up the wall and rot out your wall.

Congratulations William. You have answered all of them 99.99% correct. :wink:

Congrats, William!

Thanks guys.

Stay Tuned next week for another round. :):wink:

Well check this out…See page 9.

The window flashing was not installed in a shingle fashion and there should be no tape flashing at the bottom of the window.

Tyvec WRB flashing would be better pointed out here.

Most Window Manufacturers require the standard flashing detail as shown here.
