Checks before start-up
Before commissioning the burner, the
following checks and inspections are to
be carried out
- Operating instructions of the heat
generator manufacturer
- Setting of
- temperature regulator
- pressure regulator
- limiter
- safety guard
- Gas connection pressure min. 20 mbar
flow pressure.
- Leaks in the gas supply elements
- venting of the fuel supply pipes.
- Open flue gas ducts, an adequate
supply of fresh air.
Burner program sequence test
without flame formation
The burner control unit activates the first
time the sealing test is activated. Gas
pressure is required for this. In order to
check the entire sequence test initially
without flame formation, close the gas
manual shut-off valve again once the
sealing test is complete.
Proceed as follows:
• Open the manual shut-off valve
• Activate the boiler controller to start
the heat generator
• Follow the sealing test as performed
on the display
• Once the second valve is open, close
the manual shut-off valve again.
• The program sequence test runs until
a safety shutdown is triggered
(malfunction lamp lights up) once the
safety period has elapsed or a
shortage of gas occurs
• Disconnect the power supply to the
burner
• Open the manual shut-off valve again,
supply the burner with voltage again, if
necessary unlock and restart.
Ionisation current measurement
The ionisation current can be measured
at the measuring point intended for this
purpose. To do this, remove measuring
bridge
B10
and connect a multimeter
with a measuring range of 0-100 µA.
The monitoring current must be at least
8 µA.
