Class 5 Boiler Practice Exam

Who is responsible for ensuring proper combustion air?

1. The owner

2. The technician

3. The contractor

4. The regulatory authority

The correct answer is: The contractor

The contractor plays a critical role in ensuring proper combustion air for boilers and other combustion equipment. This responsibility typically falls within the scope of work for a contractor, who is expected to design and implement systems that facilitate adequate air supply for efficient and safe combustion. This includes conducting assessments of the installation environment, ensuring that all required ventilation openings and ducts are appropriately sized and unobstructed, and complying with standards set by relevant codes and regulations. While the owner may engage in maintaining the overall operation of the boiler and the technician may assist with setting up and servicing the system, the contractor's expertise and responsibility ensure that the system is designed properly from the outset. Regulatory authorities establish guidelines and codes that must be followed, but they do not directly manage the installation or maintenance of combustion air systems. Therefore, the contractor is integral to achieving compliance and ensuring safety standards are met in terms of combustion air requirements.
