G.I.S cut-off gas flow in the event of fan failures, now a mandatory requirement.
Sensors are installed on either side of the ductwork to monitor air pressure. These sensors are connected to an air differential switch which is activated when the pressure difference changes.
An alternative option is to monitor the current used by the fan with a fan power sensor. A 230V G.I.S monitors the switch/sensor and should a fan failure occur the gas solenoid valve will be closed and cut-off the gas flow to appliances.
When is G.I.S a Mandatory Requirement?
On installation of a new extraction canopy
On installation of a new gas pipework run
On installation of a new cook line or layout
With any fitting of Category ‘B’ equipment such as ovens, deep fryers etc.
Current gas regulations require that any kitchen fitted with gas appliances which do not have flame safety devices are advised to install a gas proving system to comply with Gas Safe Register best practice, making sure that the gas supply cannot be switched on if appliances or pipes are leaking. A Gas Proving System requires a G.I.S to operate.
