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 commissioning/replacement. Thoroughly vent
the tank and gas lines after flushing.

2.
Remove the screw inside test
connector
A
at the gas combina-
tion valve and connect the pres-
sure gauge.
3.
Open the gas shut
‐
off valve.
4.
Check the static pressure:
&
Natural gas: max. 25 mbar
&
LPG: max. 57.5 mbar
Record the actual value in the
service report on page 32.
5.
Start the boiler.
Note
During commissioning, the boiler
can (several times) enter a fault
state because of airlocks in the
gas pipe. Press the reset button
on the burner control unit after
approx. 10 seconds.
6.
Check the supply (flow) pressure:
&
Natural gas: 17.4 to 25 mbar
&
LPG: 42.5 to 57.5 mbar (at
50 mbar inlet pressure)
Record the actual value in the
service report on page 32.
Note
Use suitable test equipment with
a resolution of at least 0.1 mbar to
test the supply pressure.
