29A
Problem
with
regulating
the gas
valve,
no flame
during
ignition
1.
Check whether the gas valve is open.
2.
Measure the gas pressure at the gas valve intake.
This must be > 20 mbar or with a ULGP, NZLP (B/P)
> 40 mbar.
3.
Measure the gas pressure at the exhaust side of the
gas valve during ignition, this must be > 5 mbar or
with a ULGP, NZLP > 15 mbar.
4.
Check the gas valve wiring and connection.
5.
Change gas valve settings, parameter TP01 or TP02.
6.
Check/replace the gas valve.
33F
Low voltage
gas valve
Replace automatic burner relay
34F
Insufficient
voltage
1.
Measure mains voltage (>220VAC)
2.
Measure outgoing transformer voltage 24 VDC and
12 VDC.
3.
If the outgoing voltage is lower than 20 VDC or 10
VDC, replace the transformer.
4.
If the outgoing voltage is correct, check the wiring for
short-circuits.
35F
Problem
with the
electrical
driver
Replace automatic burner relay
50F
Gas valve
wiring
problem
Check the wiring and power plug connection.
Repair if necessary.
51A
Failure of
ionisation
signal
during while
fire is alight.
1.
Check whether the ionisation pen is obstructed in the
fireplace.
2.
Check whether the flame remains nicely in the
ionisation pen. In case the flame becomes transparent,
recirculation is occurring.
3.
Check flue duct configuration.
