Fall Is The Time To Inspect The Boiler

Autumn is a very special time of the year. In many parts of the world the changing of the seasons brings beautiful Fall foliage, harvesting of Summer fruit and the beginning of news sports seasons for us football, hockey and basketball fans.

However, Autumn also heralds the coming of Winter and the time to inspect and repair or replace your boiler. As any HVACR Pro will tell us, proper boiler maintenance can not only save significant energy dollars, it can also prevent dangerous boiler accidents.

Since ‘inspect your boiler’ was on top of my ‘To-Do List’ for next week, I started researching some refresher tips and came across a number of articles that you too may find useful when getting your boiler ready for Winter. The following tips from an article in a leading trade magazine do a good job of covering the key points.


Tips for Optimal Boiler Safety and Maintenance

  • Open the boiler vent valve or top try cock to vent air and fill the boiler with treated water to its proper level. Check that the expansion tank is properly filled.
  • Confirm that there are no signs of overheating, corrosion or erosion.
  • Test safety valves periodically. Replace leaking safety valves.
  • Ensure that all valves in instrument lines are functioning as they should.
  • Test the proper functioning of all boiler controls including the pressure gauge, low water cut off devices, thermometers, temperature controls, gauge glass and pressure relief valve.
  • Verify that the flame scanner or sensors are properly connected and functioning.
  • Test all drains and blow-offs to ensure they are functioning properly.
  • Check all instruments and safety devices for proper setting. Ensure that the water pressure regulator functions as required.
  • Check the fuel system for leaks and ensure that all fuel filters and strainers have been replaced.
  • Ensure that all shut-off valves are leak tight.
  • Ensure the re-circulation pump works as required.
  • Check that all heating system isolation valves are functioning properly.
    • Verify that there are no leaks, cracked surfaces, or bulges from any part of boiler or piping external to the boiler.
    • Verify that vent valve on a gas fired boiler is operating as required and that the vent is not clogged.
    • Verify that low water fuel cutoff control shuts off the fuel supply to the boiler as required.
