15 Gas piping (option)
15.1 Commissioning and operating
Checks before commissioning
All components of the gas piping must be checked visually:
¡ There must not be any damage to sealing surfaces (evenly fine surfaces)
¡ There must not be any visible damage to the bellows (e.g. dents, cracks, scratches or
weld spatters).
¡ All criteria mentioned also apply to the C-ring gaskets. Moreover, they must not exhibit
any buckling.
Checks after commissioning (engine in idle mode)
u After starting the engine, check all gas pipes for leaks.
Discolourations on the insulation, the smell of exhaust gas and unusual noises (whistling,
hissing) can indicate small leaks. If such new and unusual signs are found, their cause must
be determined.
Noise emission
