7.9 Measuring the gas supply pressure and static
pressure
▶ Undo the threaded plug on the test nipple for gas supply pressure
and venting by two turns.
▶ Push the test hose of the pressure gauge (measurement precision
less than 0.1 mbar) onto the pressure test nipple [1].
▶ With the burner operational (full load), check the gas supply pressure
and record the value in the commissioning report
( Chapter 7.18, page 31).
▶ If the gas supply pressure falls outside the values in tab. 12, shut
down the boiler and notify the gas supplier. Commissioning is not
permitted!
The maximum permitted gas static pressure depends on
• the proper function of the gas pressure regulator in the gas
installation in accordance with its product-specific tolerance
specifications for the permitted closing group.
• the product-specific specifications for the boiler in accordance with
the manufacturer's information.
Checking of the gas pressure regulator in the gas installation:
▶ Shut down the burner from full load.
▶ Wait 10-20 seconds and then measure the resulting gas supply
pressure/static pressure at the test nipple for the gas supply
pressure/static pressure.
The gas static pressure determined must not exceed the value, which is
defined by the closing group of the gas pressure regulator.
▶ If it is exceeded, inform the gas supplier about the required
replacement of the gas pressure regulator.
▶ If the gas static pressure is >50 mbar, there must be no
commissioning as specified by the manufacturer.
In the case of a system currently operating, take the boiler out of
operation.
▶ Remove the test hose.
▶ Carefully tighten the threaded plug on the test nipple for gas supply
pressure.
