CaterGuard GIS Gas Interlock System M-G02
M-G02 Standard GIS System with back pressure feature & additional connection for Remote
Emergency Cut-Off Switch. Large box for easier wiring. IP55

CaterGuard™ “Advanced” M-G06R Gas Interlocks save time on installations and can reduce the
amount of accessories you need to purchase. Helpful, simple operation instructions are provided
on the fascia of the unit. Choose from a variety of models to find the model best for your application.
Solenoids, gas proving systems, fan power sensors and other accessories are also part of the range

• Market-leading Gas Interlock System family
• Mechline’s CaterGuard GIS units cut off gas
flow in the event of kitchen extraction fan
• Mandatory requirement in most commercial
• Manufactured in the UK

By monitoring airflow or fan motor running current, proper functioning of a kitchen’s extraction system can be determined by the
GIS, allowing gas to then be supplied to installed appliances. Monitoring is effected by air pressure differential sensors mounted
in the extraction and/or air supply ductwork or via fan power sensors looking at fan motor current. In the event of fan failure or
a significant air flow reduction (as calibrated by the installation engineer), the sensors will actuate the Mechline GIS which in turn
closes the gas supply solenoid and thus cuts off gas supply to the kitchen appliances.

Gas safety interlock systems are required in all commercial kitchens. Gas Safe regulations and BS6173 both require a gas
interlock system to be fitted. This ensures that the commercial kitchen ventilation system is working before the gas is turned on.
This prevents a build-up of potentially poisonous gas combustion fumes in the kitchen which would be harmful to the health of
kitchen staff and others within the premises. If any gas appliances do not have Flame Failure Devices (FFD’s) fitted, then a gas
proving system must also be fitted to comply with regulations.
When to fit a GIS?
• On installation of a completely new extraction/ventilation
• 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/
convection ovens, deep fryers [with powered flues], grills,
charcoal griddles etc. proving system must also be fitted to
comply with regulations.

Smart and Compact design -
Complies with new CAIS 23 [revised]

explained fully on the fascia plate. Clear
• LED lamps & high-quality components
Key Safety Features
• All models have an anti-back pressure feature – ignores brief back draughts
in the duct and allows gas to flow.
• Back pressure sensitive with 10-second activation
• Option of ‘fail safe’ double sensor warning model [M-GO3] provides the
operator with ‘peace of mind’ and a means of avoiding system actuation
through a faulty or failed sensor. Provides clear warning that a single sensor
has failed. The system only shuts off the gas supply when both sets of
sensors actuate. (Please note in this instance that four sensors are required).
• Option of built-in emergency stop is available on units with model numbers
ending in ‘R’
• Compliant with BS6173(2009) and Regulation 27(4) of the Gas Safety
(Installation and Use) Regulations 1998
• Each GIS can handle one or two fans
• Multiple GIS units can be wired together to operate more than two fans -
Single or Double Sensor warning available
• Easy to clean and protected to IP54
