Checking The Gas Supply Pressure - Wolf MGK-130 Technical Manual And Installation Instructions

Checking the gas supply pressure

(Gas flow pressure)
Work on gas components must only be
performed by a licensed gas fitter. Work
which is carried out incorrectly may lead
to gas escaping, resulting in a risk of
explosion, asphyxiation or poisoning.
• Set the ON/OFF switch to "0".
• Open the gas shut-off valve.
• Release the plug at test nipple  and vent the gas
supply line.
• Connect the differential pressure tester at test nipple
 to "+", with "-" against atmosphere.
• Switch ON the ON/OFF switch.
• After starting the boiler, check the supply pressure
at the differential pressure tester.
Natural gas:
NB
If the supply pressure (flow pressure) lies
outside the 18 to 25 mbar range, adjustments
must not be carried out and the boiler must
not be taken into use.
• Switch OFF the ON/OFF switch. Close the gas shut-
off valve.
• Remove the differential pressure tester and
re-seal the test nipple with plug .
• Open the gas shut-off valve.
• Check the test nipple is gas-tight.
• Close the boiler again.
• Check and if necessary amend the type plate
regarding the gas type.
If any screws are not tightened, there is a
danger of gas escaping, leading to a risk
of explosion, asphyxiation or poisoning.
