Like with most pieces of equipment, owners must perform regular maintenance on boilers so they continue to function properly. The technician runs boiler tests to ensure that the boiler can perform its designated function. Any problems found in the boiler should result in an immediate call to a repair technician.

When the operator starts up a boiler that no one has run in awhile, he should disassemble the boiler and clean all the parts. The technician must especially clean and vacuum the fireside surfaces, ash pit, firebox and ducts. When the maintenance worker does not clean the boiler, the boiler can develop cracks, corrosion and can even explode.
When the boiler maintenance technician first starts working on the boiler, she should check the top of the boiler for any signs of cracks on the firebox or the boiler wall. The technician should then check for any oil leaks from the tank and above group piping/fittings. Significant corrosion to the boiler's outer sheet metal can cause alarm, as well as corrosion to the flue, piping and electrical controls. The technician must also check the draft regulator to see if it is moving freely.
The technician should test the safety relief valve to ensure that the valve works properly. Otherwise, the boiler could explode.
The manhole gasket can develop leaks and damage. Therefore, the technician should inspect the gasket for leaks and replace any leaking gaskets. The technician should replace the gaskets on the low and auxiliary water cut off controls after cleaning and inspecting these controls. The technician should always replace the hand hole and man hole plates after servicing the boiler.
The technician should lubricate all mechanical devices, such as fans, within the boiler. Otherwise, these mechanical parts can experience friction that can cause damage and ruin the boiler.
Boilers that have water lines exposed to freezing temperatures must have insulation around the water lines to protect them from freezing. Otherwise, freeze-up can block the flow of water and steam can cause heat loss, which will raise the boiler's fuel bills.
The technician should test the electronic controls to ensure that they function properly. The technician must recalibrate the controls to the changes made to the boiler.
The technician should replace some parts on the boiler no matter what the condition of the boiler. The technician must always replace the burner nozzle and the fuel filter
After repairs, the technician should give the owner a report of all repairs performed for future technicians. The owner should put all of the records for the boiler in a central location so that the owner does not lose them.
