Which item is NOT considered part of regular boiler maintenance?

• A. Adjusting the gas pressure of the burner
• B. Bleeding radiators
• C. Checking for gas leaks
• D. Lubricating the circulating pump

Answer: (A)

Adjusting the gas pressure of the burner is not part of regular boiler maintenance because it’s a specialized tuning task that directly affects combustion safety and efficiency. This kind of adjustment requires proper testing equipment, knowledge of fuel-air ratios, and adherence to gas safety standards, so it’s typically carried out by a licensed technician during commissioning or a formal service visit, not by routine operator maintenance. Regular boiler maintenance, on the other hand, includes tasks you can perform to keep the system running well and safely: bleeding radiators to remove trapped air and restore proper heat transfer, checking for gas leaks as a safety measure, and lubricating the circulating pump to reduce wear and keep the circulation system smooth. These are standard upkeep activities that don’t alter the burner’s combustion settings. So the item that isn’t part of normal maintenance is the gas pressure adjustment, while the others fit into routine maintenance practices.
