Boiler maintenance checklist for you from NextGen boiler experts

Boiler Maintenance Checklist:

Following a regular maintenance schedule for your building's boiler plant will go a long way toward minimizing breakdowns and service interruptions. Here are some key boiler maintenance checklist from NextGen Boiler and gas engineer experts that you should follow to keep your boiler in a top condition.

Annual Maintenance

  • These maintenance items should be done once a year by a heating contractor between heating seasons (June to
  • Inspect and clean fireside surfaces.
  • Inspect all burner refractory material.
  • Inspect all manhole gaskets for leaks.
  • Inspect and test all system valves.
  • Inspect and test all safety valves.
  • Clean and rebuild low water cut-off.
  • Recalibrate all operating controls.
  • Overhaul feed water pumps.
  • Clean condensate receiver.
  • Inspect electrical terminals.
  • Switch boiler automation to summer mode.
  • Check fuel oil levels.
  • Clean and inspect chimneys.
  • Clean and tune boiler and components.

Periodic Maintenance

These items should be addressed by the building's maintenance staff on a continual basis, or as often as indicated below:

  • Check and maintain proper oil level in compressor lube tank (daily). Use SAE 20/30 oil.
  • Clean oil filters at least twice a week:
  • 1. Shut-off power to pump motor.
    2. Close shut-off valve.
    3. Pull out filter. Clean filter and re-insert into housing.
    4. Place strainer cap into proper position, restart pump motor, and check vacuum.
    5. Vacuum reading must be high; if not, check seal on cap. If reading is high, then open oil valve.
    6. Check oil pressure reading at the burners.

  • Keep sight glasses clean. This allows for a clear view of the burner flame and any carbon build-up on the boiler's combustion chamber (as needed).
  • Keep air filters clean. A clogged air filter can lead to poor air/oil mixture and carbon build-up (as needed).
  • Check oil circulation temperature at sidearm pre-heaters. Inlet temperature should be 110° F to 120° F, and outlet temperature should be 140° F to 150° F for No. 6 oil (daily).
  • Flush drain low water cut-offs/sidearm oil pre-heater (twice a week).
  • Flush drain low water cut-offs while burner is on and a flame is present in the boiler's combustion chamber. When the unit is flushed, the flame should turn off. Allow the burner to start before checking other low water cut-offs.
  • Flush down water-line heater, shut off lower isolation valve, open drain valve to flush unit, shut drain off valve, and reopen isolation valve.
  • Conduct boiler bottom blow down to clear sludge and sediment, control high water, and control chemical treatment concentrations (monthly or as needed).
  • Monitor the make-up water being added to the boiler and/or the boiler feed unit. Since the system operates via closed loop, an excess amount of fresh (untreated, oxygenated) water supply is detrimental to boiler components and is often a sign of a leak in the system.
  • Monitor smoke alarm on a weekly basis:
  • 1. Wipe light source and receiver.
    2. Smoke alarm unit should not be set at its highest point.
    3. Unit should be set in accordance with NYC Buildings Department standards.

  • Maintain a rigorous boiler chemical feed water treatment program.
  • Maintain a boiler room log to record any problems and routine maintenance.
  • Check combustion, inspect burner controls, and inspect burner operation.
  • Conduct trap inspection program with replacement of trap elements in apartment units and steam traps within the cellar.
