Performed annual tune-up on a Peerless propane boiler. Cleaned the burners, heat exchanger, igniter, flame sensor, and pilot assembly. Inspected safety controls, relief valve, expansion tank, venting, and overall hydronic system function. Bubble-tested the pilot line and checked carbon monoxide levels—no leaks detected. Flushed sediment from the indirect water heater. Verified proper operation; the system is functioning correctly at this time. Emailed estimates to drain the Modine in the garage and add antifreeze to the boiler system.
