Checking the static and supply pressure
Danger
CO build-up as a result of an incorrect burner setup can have serious
health implications.
Carry out a CO test prior to and after work on gas equipment.
Operation with LPG
Flush the LPG tank twice during com-
missioning/replacement. Thoroughly
vent the tank and gas supply lines
after flushing.
1. Close the gas shut-off valve.
2. Undo the screw inside test connec-
tor A at the gas train, but do not
remove it, and connect the pres-
sure gauge.
3. Open the gas shut-off valve.
4. Measure the static pressure and
record it in the service report.
Set value: max. 57.5 mbar
5. Start the boiler.
Note
During commissioning, the boiler
can enter a fault state because of
airlocks in the gas pipe. After
approx. 5 s press "E RESET" to
reset the burner.
6. Check the supply (flow) pressure.
Set value:
&
Natural gas: 20 mbar
&
LPG: 50 mbar
Note
Use suitable test equipment with a
resolution of at least 0.1 mbar to
measure the supply pressure.
7. Record the actual value in the ser-
vice report.
Take the action shown in the table.
8. Switch OFF the system at the con-
trol unit (the boiler shuts down),
close the gas shut-off valve,
remove the pressure gauge and
close test connector A with the
screw.
