Each appliance must be interlocked with what system to ensure safety?

Interlocking appliances with the Mechanical Combustion Air Supply System is essential for ensuring safety in settings where combustion processes occur. This system is responsible for supplying the necessary air required for combustion in various appliances, such as boilers and furnaces. By interlocking the appliance with the combustion air supply, the system can regulate and ensure that adequate air is available before allowing the appliance to operate. This prevents scenarios where insufficient air may lead to incomplete combustion, which can create dangerous conditions such as carbon monoxide build-up, overheating, or even explosions.

The importance of this interlock becomes clear in applications involving fossil fuels, as these fuels require a consistent and adequate supply of air for safe and efficient operation. Without this safety feature, there is a heightened risk of hazardous incidents, including fires and emissions of poisonous gases, which poses serious risks to both individuals and property. Therefore, the interlock with the Mechanical Combustion Air Supply System is a critical safety measure in the operation of combustion appliances.
