Where To Place Your Carbon Monoxide Alarms
- On each level of your home
- Outside and near sleeping areas such as bedrooms
- In the area of any major gas-burning appliances such as a furnace or water heater
- At least 15 feet from gas-burning appliances (not any closer)
- On the wall or ceiling. The weight of CO is very close to that of normal atmosphere, so the mounting height does not matter.
In general, follow the manufacturer's instructions.
