Gas interlocks are a legal requirement for commercial kitchens fitted out since 2001. They check that the ventilation is working.

​

You need to have a gas interlock system fitted in all new commercial kitchens with a gas appliance. Older kitchens without a gas interlock system must have one fitted when carrying out major refits. If you install a new canopy, replace gas appliances or alterations to the gas pipework. If a kitchen pre dating 2001 doesn't have an interlock fitted a risk assessment must be carried out to establish whether an unacceptable risk is likely to arise. You're advised to consult a commercial catering gas safe engineer if your kitchen pre dates 2001.

 

There are two methods that gas interlocks can use. Air pressure differential switches fitted in the ducting; this method physically checks for airflow before allowing the gas solenoid valve to open. Modern method for gas interlocks uses current monitors to check the power supply going to the fans and control the gas solenoid valve accordingly. If the fans fail or when turned off the gas solenoid valve will automatically close.

Energy saving gas interlock systems are ideal for those looking to reduce the energy used during cooking.
