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?
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.

Thanks for all responses.

Best to check local code. I have seen such applications with no fire
door, but it is smart to have one. You may also need a CO detector in
the boiler room and possibly the other area too. How are you going to
handle combustion air? If this is a new boiler with outside air
intake, that covers you, otherwise you need a vent in the door.
