What it is
The Vaillant gas section with regulator is a gas-carrying assembly used on Vaillant EcoTEC Plus and EcoTEC VU/VUW appliances. It combines the gas section body with an integrated regulator, which holds the gas supply at a steady pressure so the burner receives a consistent input across the modulation range. The assembly forms part of the gas train between the supply inlet and the burner, and is supplied under Vaillant part number 0020148383.
Signs this part needs replacing
- Boiler locks out or fails to fire despite a healthy ignition and flame detection circuit
- Burner flame is unstable, weak or noticeably uneven across the burner bar
- Gas input pressure drifts or cannot be set within the values given in the appliance servicing instructions
- Whistling, humming or other abnormal noise from the gas train during firing
- Repeated pressure-related fault codes logged on the appliance display
Before you order
- Confirm the appliance GC number and model variant against the compatibility list, as several EcoTEC Plus revisions use different gas train assemblies.
- Check the alternative number 1383445 against any documentation supplied with the appliance.
- Inspect the gas section joint seals and replace them if they show hardening, flattening or contamination.
- This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
