Arrived onsite to perform an annual tune-up on a propane boiler. The gas line is installed in a way that prevents the boiler from being disassembled for a thorough cleaning. I provided an estimate to rework the gas line. Performed annual tune-up on a Crown propane boiler. Checked the burners, igniter, flame sensor, and pilot assembly. Cleaned the heat exchanger. Inspected safety controls, venting, and overall hydronic system function. Bubble-tested the pilot line and checked carbon monoxide levels—no leaks detected. During testing, the relief valve leaked, so I replaced it. The expansion tank was also leaking and had rust holes, so I replaced that as well. Verified operation—system is working properly at this time.
