Checking The Usage; Installation - Honeywell Kromschröder GIK Series Operating Instructions Manual

2 CHeCKInG tHe UsAGe

Air/gas ratio controls GIK for maintaining a constant
gas/air ratio of 1:1 and for gas pressure control in
systems without preheated combustion air.
Variable air/gas ratio controls GIKH for maintaining
a constant gas/air ratio of 4:1 and for gas pressure
control in systems using a recuperative air preheating
system.
GIK, GIKH for continuous control. GIK..B, GIKH..B
for staged control.
GIK..L, GIKH..L for air only.
This function is only guaranteed when used within the
specified limits – see page 8 (12 Technical data).
Any other use is considered as non-compliant.

3 InstALLAtIon

CAUtIon
Incorrect installation
Please observe the following to ensure that the
unit is not damaged during installation:
– Always install a manual valve, filter and safety
valve upstream of the air/gas ratio control or
5
variable air/gas ratio control.
– The installation location must be dry, see page
8 (12 Technical data).
– Dropping the device can cause permanent
2
damage. In this event, replace the entire device
and associated modules before use.
– Install the unit in the pipe free of mechanical
stress.
– Do not clamp the unit in a vice or use it as a
lever. Risk of external leakage.
➔ Only install the unit in horizontal pipelines, the spring
dome must point vertically downwards.
➔ We recommend that a slowing down section of
3 x DN be provided downstream of the regulator.
