Which would not be a prohibited location for a fuel-fired, atmospherically-vented appliance?

• A. Sleeping Room
• B. Closet or Alcove
• C. Bathroom
• D. Surgical Room

Answer: (B)

Fuel-fired, atmospherically vented appliances rely on the room to provide combustion air and vent through natural draft, so they must go in spaces that can supply adequate air and maintain safe clearances from combustibles. A closet or alcove can be an allowable location because, when designed with proper ventilation openings for combustion air and the required clearances, it can meet those conditions. Sleeping rooms are avoided because occupants could be exposed to combustion byproducts, including carbon monoxide, while the space may not have the required outside air supply. Bathrooms are avoided due to moisture and the potential safety hazards near water, which can complicate venting and ignition safety. Surgical rooms are avoided because they require highly controlled, sterile ventilation that would be compromised by combustion byproducts and ignition sources. So, a closet or alcove is the location that would not be prohibited, assuming it meets the code’s ventilation and clearance requirements.
