The customer reported that their oil boiler would run but would not stay lit. With the customer’s approval, I performed a full annual service, including replacing the nozzle and strainer, and brushing and vacuuming the boiler and smoke pipe. I also vacuumed the heat exchanger as thoroughly as possible; however, the boiler door cannot open fully due to the piping configuration. During the inspection, I found the electrodes to be excessively worn and in need of replacement. With the customer’s approval, I installed new electrodes. I then performed a combustion test, draft test, and verified pump pressure and pump cut-off. I also checked all system safeties to ensure proper operation, including confirming that the boiler shuts off at high limit. The boiler is now igniting and running properly, and all systems are operating as expected at this time.
