Greeted John and proceeded to perform a PTU on a Peerless oil fired boiler. I replaced the oil tank filter along with the fuel pump strainer. I removed the gun assembly, degreased and scrubbed clean. I also replaced the original factory nozzle with a 85/80B. I reassembled the gun assembly, restored power, turned up the thermostat and bled the oil lines. I reset the barometric damper. The boiler fired, ran cycled and reached temperature accordingly. All is good, no issues to report at this time. John was happy with the service.
