Again, sorry about all the posts.
I have a partitioned furnace room (gas furnace and water heater) with 2 high vents and 2 low vents built into the walls. The door to the room is louvered.
Can I use a screen door instead of the louvered door?
Reason is that the furnace room can be buggy, and my fiancée gets freaked out when she's in the adjacent room. The easy fix would be to put screening on the inside of the louvered door.
Any possible problems with that?
