Performed annual maintenance on the Thermo Pride oil furnace. Replaced the nozzle, oil filter, and pump strainer. Brushed and vacuumed the heat exchanger and flue pipe. Tested and verified proper operation of all system safeties and burner components. Found the jet line to be over-tightened and not seating correctly on the J-tube assembly. With approval, replaced the jet line. Performed combustion, smoke, and draft testing. The system is operating properly at this time. Discussed with Brianna the need to replace the uncoated oil line from the tank to the furnace, as well as updating the oil filter and replacing the leaking Fireomatic safety shutoff. Estimates for this work will be provided.
