Fuel-fired appliances should not be located in which type of rooms?

Fuel-fired appliances should not be located in sleeping rooms and bathrooms primarily due to safety concerns related to ventilation, carbon monoxide exposure, and the potential for hazardous conditions.

Sleeping rooms are designed for rest and are often not equipped with the necessary ventilation to support fuel-burning appliances. If a fuel-fired appliance were to malfunction, the risk of carbon monoxide poisoning would increase significantly, as these rooms are typically sealed to maintain comfort, making it difficult for harmful gases to dissipate.

Bathrooms also pose similar risks; they often contain high humidity levels due to bathing activities. The presence of fuel-fired appliances in such an environment can lead to condensation and potential corrosion of equipment, along with inadequate ventilation that heightens the danger of carbon monoxide buildup.

In contrast, other spaces such as living rooms, kitchens, laundry rooms, and garages usually have better ventilation options to safely accommodate fuel-fired appliances, making them less hazardous than sleeping and bathing areas.
