Where should the smoke alarm be mounted?

The smoke alarm is most effectively mounted in the chimney or smoke stack because this location allows it to detect smoke from combustion products before it enters the living areas of a building. By placing the alarm in the chimney or smoke stack, it can provide an early warning of any potential issues arising from the burner, such as incomplete combustion or malfunctioning equipment, which could lead to dangerous smoke or carbon monoxide buildup.

Mounting a smoke alarm inside the combustion chamber would expose it to extreme temperatures and conditions that could lead to malfunction or damage. Similarly, placing it near the oil supply tank would not provide an effective means of smoke detection, as this area is typically not where smoke would travel. Positioning it on the burner unit may not allow for adequate detection of smoke that escapes from the system, as it could either miss the smoke altogether or fail due to exposure to operational conditions.

For these reasons, ensuring that smoke alarms are appropriately located in chimneys or smoke stacks is crucial for effective smoke detection and safety.
