  • Check oil level in compressor {#4 and #6 oil burners}
  • Check water temperature and oil pressure gauges for correct readings
  • Make note of water addition {if any}
  • Take reading of stack thermometer
  • Check flame at high fire {#4 and #6 oil burners} for length and color
  • Once a week: Test low water safety cut off switch

  • Clean fire eye
  • Clean smoke detection eye on chimney
  • Check pre-rotation veins for any oil residue
  • Check combustion chamber for any oil residue
  • Once every six months: Thoroughly clean burner and burner assembly
  • Clean tubes {#4 and #6 burners} {once a year if #2 oil or gas}
  • Test the safety relief valve on the boiler
  • Once a year: Have a complete burner overhaul
  • Conduct an efficiency test on the burner
  • Clean stack and breaching
  • Once every two years: Have a waterside boil out done
  • Once every five years: {#4 and #6 oil burners}
  • Have the oil tank cleaned and inspected
  • Have the oil lines to and from the boiler steam-cleaned

The above is a recommended schedule of maintenance. You should consult your boiler manufacturer just in case additional maintenance is required. Safety is always the first consideration in boiler operations. Efficiency is second.
