Collection: Gas Interlock Parts

Commercial Kitchen Gas Safety & Regulatory Compliance

Gas interlock systems are a mandatory safety control in commercial kitchens where gas appliances are used in conjunction with mechanical ventilation. In accordance with BS 6173, IGEM / UP / 19, and Gas Safe best practice, gas interlocks ensure that the gas supply is automatically isolated if the ventilation system is not operating correctly.

These systems are designed to reduce the risk of incomplete combustion, excessive heat build-up, and gas accumulation by preventing gas flow unless adequate airflow is proven.

What Is a Gas Interlock System?

A gas interlock system monitors airflow from the kitchen extract and/or supply ventilation system. If sufficient airflow is not detected, the system prevents the gas solenoid valve from opening or closes it immediately.
This interlocking of gas supply and ventilation is a core requirement of BS 6173 and is routinely verified during Gas Safe inspections of commercial catering installations.
