Ideal Classic 230 240 250 260 270 280 NF Boiler Automatic Air Vent 113116

Product Overview

The Ideal Classic Boiler Automatic Air Vent (Part Number: 113116) is an air-release component designed for selected Ideal heating systems.

The automatic air vent helps remove accumulated air from the boiler's central heating water circuit, supporting normal water circulation and reducing air-related operating problems.

The component is identified as a 3/8-inch Automatic Air Vent. Its function is to release trapped air from the heating circuit without requiring continuous manual venting.

ℹ️ Product Condition Options:

This part may be available in New or Refurbished condition. Please select your desired option from the dropdown menu above. Refurbished components should be professionally inspected and tested for correct operation and leakage before installation.

Technical Insight & Common Failure Symptoms

The automatic air vent is a mechanical device designed to release air that accumulates within the boiler's heating circuit.

Automatic air vents typically use an internal float-operated mechanism. As air collects inside the vent chamber, the float lowers and opens the air-release valve. When water rises within the chamber, the float closes the valve to prevent water escaping during normal operation.

Over time, the vent may be affected by internal contamination, corrosion, deteriorated seals or problems with the float mechanism.

Possible symptoms that may indicate an automatic air vent or associated heating system problem include:

• Air remaining trapped within the boiler or heating circuit.

• Gurgling or bubbling noises during heating operation.

• Water dripping or leaking from the automatic air vent.

• Vent failing to release accumulated air correctly.

• Reduced water circulation associated with airlocks.

• Intermittent heating performance caused by trapped air.

• Visible corrosion or deterioration around the vent body.

These symptoms do not necessarily confirm a faulty automatic air vent, as similar problems may result from system leaks, circulation faults, incorrect filling procedures or other hydraulic components. Correct professional diagnosis should be carried out before replacement.

Compatibility

This part (MPN: 113116) is associated with selected Ideal Classic NF boiler systems.

Please verify the exact boiler model, GC number, part number, 3/8-inch connection size and component specifications against the manufacturer's technical documentation before ordering to ensure correct fitment.

Safety Advice

Boiler automatic air vents and associated hydraulic components should only be inspected, removed or installed by a suitably qualified and competent heating engineer.

Always isolate the appliance and allow the heating system to cool before carrying out any work. The relevant heating circuit must be safely isolated and depressurised before removing the vent. Follow the manufacturer's servicing instructions and complete all required pressure, leakage and operational safety checks before returning the boiler to service.
