Gas Interlock Control Panels -



Cost Effective Gas Interlock Panel

The Merlin Ventilation Interlock System is designed specifically for use in commercial kitchens to meet BS6173: 2001, which is now a much-recognised standard in the catering industry.

These panels can be used with kitchen appliances that do have flame failure devices or appliances that do not have flame failure devices. 

The Merlin Ventilation Interlock System acts as an interlock between the ventilation system and the gas solenoid valve. It ensures the gas solenoid valve cannot be opened until the ventilation system is proven to be operating. 


  • Easy to install
  • Easy to use
  • 240v normally closed but others can be supplied on request
  • Three year warranty
  • UK Manufactured


To operate the Merlin Ventilation Interlock System the fans should be turned to the “on” position, once our panel receives a signal to indicate the fans are operating turn the key to the “on” position this will open the gas solenoid valve. If the fans should fail, the “fan fault” LED on the panel will illuminate and the gas solenoid valve will close. When there is a “fan fault” the supply fan or extract fan led will flash to inform the electrician or kitchen staff which fan has failed.

Operating the system in the above manner will ensure the requirements of BS6173: 2001.

A Gas Safe installer would be required to fit the gas solenoid valve. Check the register at
