What is Gas  interlock System (GIS)?

An interlock is a system that will not allow the gas to be turned on until the ventilation system is operating correctly.


Why is an interlock required? 

An interlock is required to ensure the safety and comfort of the kitchen staff. If the ventilation system is not operating correctly, gases including carbon monoxide and nitrogen dioxide can build up to dangerous levels. These two gases give most concern to the Health and Safety Executive (HSE). 




• On installation of a completely new extraction/ventilation canopy
• On installation of a completely new gas pipework run
• On installation of a completely new cook line or layout

With any fitting of Category 'B' equipment e.g. combination ovens, deep fryers, grills, charcoal griddles. This includes replacements to an existing layout
SAFETY VALVES -  Low Pressure Cut-off Valves, Straight With UPSO


Safety valves which cut off the gas following a loss of inlet pressure. The valves may be manually reset. The valves should only be reset after inlet pressure has been restored and any taps and/or valves have been checked closed. It is in theory possible to re-pressurise the system if there is an escape path smaller than the 1 mm bypass valve. The valves shut at the preset value of 15 mbar (6" wg). They must be mounted upright in horizontal pipework.
