Arrived on site to perform an annual tune up on propane boiler. After our initial inspection, we provided an estimate to perform the work. It was accepted. We started by turning off the gas and power to the unit. We then removed the pilot assembly and burner tubes. We found that the thermocouple had some buildup on it and part of the nut looked like it had melted. Wire brushed the burner tubes and inspected the heat exchanger. Heat exchanger had some combustion particle buildup but it wasn’t terrible. Provided an estimate to replace the thermocouple but it was declined as he can do it himself. We then reinstalled pilot assembly and restored gas supply. We tested gas pressure and found it was only 6” w.c. This is extremely low as it should be 10” w.c. minimum. Adjusted it at the gas valve to get desired reading. Performed combustion analysis. System is operating safely at this time. Thank you for your business!
