In creating a room around the boiler, I'm aware of required clearances and fire rated sheetrock for walls and ceiling. But I've noticed fire doors at the store that have a number of hour ratings.

1. Anyone know which time-rated door to choose?

What time-rated door to use for the boiler room?

If you can get one with a 2400 hour rating, you'll have over 3 months to
escape.

2. Does the boiler room and the (open layout) basement each need a smoke detector for each of these two "rooms"? I know they have to be wired, and if there are two, wired together as well.

I've a single family home in New York.

I miss NY.

Thanks for all responses.
