Maintenance Tips

• Annual professional tune-up: Have a qualified HVAC technician inspect the boiler before each heating season — check the burner, heat exchanger, controls, and flue.

• Check pressure & water level: Monitor system pressure and water level weekly; adjust as recommended.

• Bleed radiators/baseboards: Release trapped air to maintain efficient heat distribution.

• Inspect venting: Ensure flue, chimney, and air intake remain clear of debris and safely sealed.

• Flush system periodically: Sediment can accumulate over time; periodic flushing helps preserve efficiency and lifespan.

• Watch for leaks: Check around valves, fittings, and sections for signs of water leakage.
