• Daily: Check water level
• Check oil level and make note of level {if gas, read gas meter}. Determine daily consumption
• 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

• 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
