In a commercial kitchen, cooking appliances burn a lot of gas in a small space. Without extraction, fumes and carbon monoxide build up quickly. A commercial kitchen gas interlock in Preston makes sure gas only flows when the ventilation is working.
SMR Gas Maintenance Ltd installs, links and repairs gas interlock systems for restaurants, canteens, schools and food production sites across Preston, Lancashire and the North West. Gas Safe 562186.
How a gas interlock works
A gas interlock panel monitors the extraction and supply fans, usually with airflow or current sensors. If the fans stop or fail, a solenoid valve closes and shuts off the kitchen gas. Most systems also include an emergency stop button and a proving system that checks for open burner valves before gas is restored.
When you need one
• New commercial kitchens and refits
• Replacing or adding cooking appliances
• When existing extraction has no link to the gas supply
• When an inspection has flagged the missing interlock
Linking gas to an existing fan system
Many sites already have extraction fans but no working link to the gas. We survey the fans, controls and gas supply, then fit a suitable interlock panel, sensors and solenoid valve. We test the whole system so gas shuts off when the fans stop.
Common interlock faults
• Airflow sensors blocked with grease
• Fans running slowly after speed controllers are turned down
• Faulty solenoid valves failing to open or close
Emergency stop buttons left pressed
• Wiring altered during kitchen refits
Food production and larger sites
Industrial food production often combines ovens, fryers and process burners with complex ventilation. We match theinterlock design to the plant and the production pattern.
FAQ
Why won't our kitchen gas come on?
Often the fans aren't running or the interlock has detected low airflow. Check the fans and emergency stop, then call us if the gas still won't restore.
Can you add an interlock to our existing extraction?
Usually yes, after a survey of the fans and gas supply.
How long does an installation take?
Most kitchen interlock installs are completed in a day, often out of service hours.
Do you issue paperwork?
Yes. You receive commissioning records and the relevant commercial catering gas safety paperwork.
