False flame signal
cause

No ignition spark

Ignition spark, but no
flame

Flame, but insufficient
ionization

Defective gas valve

No or to little gas
pressure

VPS switch wrongly
adjusted

Bad connection

Defective sensor

Sensor not correctly
mounted

Ionization current has
been measured, while
there may not be a
flame
11 Control stops and faults
Check/solution

Cascade valve does not open

Trap is blocked

Heat exchanger is dirty

Check the air supply

Check:
connection between ignition
cable and transformer

electrode distance, this must
be1/8 - 1/6 inch (3 - 4 mm)

breakdown to earth

condition of the burner set
(burner set/electrode seal)

earthing

bad actuation on SU board

Check:

is the gas cock opened?

is the inlet gas pressure
sufficient?

is the gas pipe vented?

correct gas block operation and
adjustment?

is the air supply or flue gas
discharge blocked?

condition of cable bundle to gas
block

bad actuation on SU board

Check:

condition of the electrode and
earthing

condition of cable bundle
between ignition cable and
transformer

if gas cock is fully opened

if the gas pressure is sufficient

Is the gas cock opened?

Is the gas pressure sufficient?

Are the VPS switches correctly
fitted?

Gas valve is leaking or is stuck
in the open position.

Is the wiring in order, plugs V1,
V2 not mixed up?

Check the VPS settings

Replace the sensor if
necessary

Check if sensor is correctly
mounted

Burner glows as a result of a
high CO percentage (adjust
2


Check the ignition / ionization
electrode

Gas valve is leaking or is stuck
in the open position.
