Basic Operation

When switched on via the key switch the GasGuard I system pressurises the gas pipework then performs an integrity check to ensure that no downstream outlets or appliances have been left open/on.

Upon receiving a fault signal from any external devices, the GasGuard will ensure that the gas is isolated to prevent any potential issues.

The easy to use engineers button can be used to display any faults with the system and allow gas through for commissioning and purging.
