Greeted Billy, and proceeded to perform a PTU on a Peerless oil fired steam boiler. I replaced the oil tank filter along with the oil pump strainer. I removed the gun assembly, degreased, scrubbed and cleaned. I replaced the nozzle with a 70/75A. Checked and inspected the electrodes, made adjustments. I reassembled the gun assembly, restored power, fired up the boiler, and bled the oil lines. I observed the boiler run, cycle and reach temperature. As a second service, I checked and inspected the hot water heater. I connected the hose and flushed the sediment, filled the heater and restored power. Flushed the faucets. Both jobs completed. Customers were very happy with the service.
