Maintenance Tips

• Annual professional inspection: Have a licensed HVAC technician check the boiler each year — burner, heat exchanger, combustion, and controls.

• Monitor pressure & water level: Maintain system pressure within recommended ranges and inspect expansion tank condition.

• Bleed air from heat circuits: Release trapped air in radiators or baseboards to ensure even heating.

• Inspect venting: Ensure chimney/flue paths and intake air openings are clear and properly sealed.

• Check for leaks: Periodically look for signs of water or gas leaks around valves, joints, and pipe connections.
