POSSIBLE CAUSES
The solenoid valves is passing too
little gas.
The solenoid valves are defective.
The ignition arc is irregular or has
failed.
The pipe has not been purged from
the air.
The air pressure switch does not
change over to the operational posi-
tion.
The flame exists.
The pressure test point
fig. 9, page 7) is badly positioned.
The gas pressure in the gas-mains
lies very close to the value to which
the gas pressure switch has been set.
The sudden falling-off pressure at the
opening of the valve causes the
opening of the pressure switch.
However this only temporarily, be-
cause the valve immediately closes
again, so then does the pressure
switch, because the pressure builds-
up again, causing the cycle to be
repeated over and over.
: – Flame failure
– Earth probe
