Overview
The GasGuard gas proving system is designed to meet the requirements of IGEM/UP/11 for educational establishments and is a BS6173 and IGEM/UP/19 compliant ventilation interlock.
The GasGuard is ideal for when appliances are not fitted with flame failure devices, or can be used to provide additional peace of mind when they are.
With a backlit LCD, the GasGuard will provide a clear indication of any issues with external devices such as ventilation systems, and will provide details of gas pressures and Gas Sensor levels.

Basic Operation
Turning the key switch to ON will start the proving cycle by energising the Gas Valve to pressurise the system, the valve will then close and the pipework is monitored for 30 seconds for pressure drops.
Upon receiving a fault signal from any external devices, the GasGuard will ensure that the gas is isolated to prevent any potential issues and the LCD will advise exactly what the issue is and how to rectify it.
Turning the key switch to the OFF position or pressing the panel stop button will isolate the gas supply.
The internal Open and Display buttons are also available to aid with commissioning and fault finding, providing details of ALL interfaces at the press of a button.
