What it is
The Sime automatic air vent, part number 6013101, is a boiler component that automatically releases trapped air from the heating circuit. It is fitted across a wide range of Sime gas and LPG boilers, including the Ecomfort, Format, Climit and Economy families. Its role is to keep the system free of air pockets so that water circulation and heat output remain consistent.
Signs this part needs replacing
- Gurgling or trickling noises from the boiler or pipework as air passes through the system
- Radiators that stay cold at the top while the bottom heats normally
- Repeated pressure loss on the boiler gauge with no visible external leak
- Water weeping or staining around the vent body
- Boiler locking out or cycling shortly after firing
Before you order
- Confirm your appliance model and, where shown on the data plate, its GC number against the fit list above
- Check the part number 6013101 matches the vent currently fitted
- Compare the existing vent's body and connection against the replacement before removing it
- Isolate the appliance and drain or depressurise the relevant section before fitting
