Air/ Gas Ratio control

The air/gas ratio controls GIK serve to maintain a constant AIR/GAS ratio and to regulate the gas pressure upstream of gas burners on installations without preheated combustion air. GIK for continuous control (Fig.), GIK..B with bypass for high/low/off control. Zero-pressure regulation with conversion kit . EN 746-2 demands that a burner always be ignited with a stable gas-air mixture. This requirement can be met with the aid of the AIR/GAS Ratio Control. EC type-tested and certified to the Gas Appliances Directive (90/396/EEC).
