Performed the maintenance for one oil fired hot water boiler, replaced the oil nozzle, oil filter, and pump screen. The burner uses a 1.25 60° w nozzle, a spin on oil filter and an "A" pump screen. Removed and cleaned the electrodes and the combustion head, opened the top of the boiler and thoroughly brushed it and vacuumed it. Swung open the front door and inspected the combustion chamber and the target wall and confirmed that everything is in good condition and is clean. Started up the boiler and performed a combustion test and confirmed that the burner and boiler are operating properly.
