GIK50R02-5

Product Description

ApplicationThe gas/air ratio regulators GIK and GI 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 and GI for modulating control, GIK..B with bypass for high/low/off control. Zero-pressure regulation with conversion kit.

Features

- With spring for compensating for the weight of the diaphragm assembly in the case of modulating control.

- Gas/air ratio regulator with inlet pressure compensationdiaphragmand zero shut-off.

- The GIK can be converted to the GIK..B. The bypass screw must be exchanged for this purpose.

Function

The gas/air ratio regulator is activated by the pressure of the combustion air line. It regulates the gas outlet pressure in the ratio 1:1 to the air control pressure.The burner capacity is varied with the aid of the air control valve.

Furnace pressure fluctuations have the same effect on gas and air throughput, thus meaning that the gas-air mixture does not change.

The low fire rate can be set by adjusting the regulator spring.

In the case of high/low control (GIK..B), the spring should be fully relaxed. The min. flow flows only through the bypass.

The setting at high fire is performed via orifices or valves on the burner

Ambient conditions

Icing, condensation and dew in and on the unit are not permitted.

Avoid direct sunlight or radiation from red-hot surfaces on the unit. Note the maximum medium and ambient temperatures!

Avoid corrosive influences, e.g. salty ambient air or SO2. The unit may only be stored/installed in enclosed rooms/buildings.

Long-term use in the upper ambient temperature range accelerates the ageing of the elastomer materials and reduces the service life (please contact manufacturer).

This unit is not suitable for cleaning with a high-pressure cleaner and/or cleaning products.
