spark
A spark plug (sometimes, in British English, a sparking plug, and, colloquially, a plug) is a device for delivering electric current from an ignition system to the combustion chamber of a spark-ignition engine to ignite the compressed fuel/air mixture by an electric spark, while containing combustion pressure within the engine. A spark plug has a metal threaded shell, electrically isolated from a central electrode by a ceramic insulator. The central electrode, which may contain a resistor, is connected by a heavily insulated wire to the output terminal of an ignition coil or magneto. The spark plug's metal shell is screwed into the engine's cylinder head and thus electrically grounded. The central electrode protrudes through the porcelain insulator into the combustion chamber, forming one or more spark gaps between the inner end of the central electrode and usually one or more protuberances or structures attached to the inner end of the threaded shell and designated the side, earth, or ground electrode(s).
Spark plugs may also be used for other purposes; in Saab Direct Ignition when they are not firing, spark plugs are used to measure ionization in the cylinders – this ionic current measurement is used to replace the ordinary cam phase sensor, knock sensor and misfire measurement function. Spark plugs may also be used in other applications such as furnaces wherein a combustible fuel/air mixture must be ignited. In this case, they are sometimes referred to as flame igniters.
Hi Guys,
Im having an issue with the above boiler and would be very grateful if anyone could shed some light on it.
Wether its hot water usage,thermostat/timer or manual use,The boiler fires up for about 3 seconds then shuts off.The pump keeps on running and i get a red error led lit next to...

Am in the middle of repairing a Glowworm flue-saver 55f
It wont spark.
1- fan runs
2- pressure switch is making contacts - heard the click and multi meter checked
3- check ignition lead continuity - OK
4- check distance between pilot and spark electrode - 4mm ok
5- i can see a capacitor...
Has anyone come across this faulty before.
LPG, 40mbar standing, 37mbar wp when boiler goes to fire, boiler runs through ignition sequence, 15mbar bp going through to buner, electrodes spark but burner doesnt ignite. There is a good spark across electrodes. Spark gap ok. Flue in tact and sealed...
Hi fellas, Im a spark so go easy on me!
Got a call out to Electrical fault on a UF heating system today
No voltage to the pump, when I traced the fault it seemed the 230 supply went from the control center to a PCB marked "rx 58 pump logic module".
Various conductors leave the module but two...
Not fitted one before (or looked into them.) Guy wants one doing, an Aqualisa. Looked up a couple online but not very clear on how they're powered...
Mention of a processor box. Does this just get sited somewhere where's there's a power point and plugged in or is it more complicated?
I've no...
can anyone give me a quick hand with this fault-i have a 24 cdi of with ignition fault-slow flashing central heating light, when u reset pump runs and light flashes again any help would be great as i dont have the sequence of operation to hand
Problem.
Boiler igniting gas run for approx 10 secs, Shut down 30deg flashing.
Changed sensing electrode then lead and subsequently pcb, still the same prob.
Found outlet sealing collar rusted and broken, replaced.
The problem as altered slightly in that it still shuts down but no fault lights...
Hi Guys
Some help from the experts would be appreciated before I end up in the divorce courts!!!! I have a Firebird Heatpac 70/90

Hello,
Just been to a job to renstate gas to an empty property the boiler is the older type Vaillant VCW GB 282 EH , twin enamel doors. All ok until the boiler would not light up. Pressure good and hydralics all moving freely all fuses good, fan good. No spark to ignite gas . Am i missing...
can anyone advise me a reliable fix for an error code on a Glow-worm Flexicom with an F1 error, i know its ignition, the condense is not blocked. So is it PCB or spark electrodes?
Thanks
Can anyone help had 2 engineers out now and they still can not pin point my boiler problem i have a sabre he 35 red light on fan running pump running but no spark engineer has cleaned fan and venturi tube and silicone air tubes fitted new air presure switch still not working the other engineer...
I gather Ferroli's are rubbish. Shame my installer didn't know! Have 3 storey house, not sure have big enough boiler to start. Anyway had intermitent H & C in shower and all sinks for about 3 months. Now only cold last week. Ferroli supposed to book engineer visit y'day, but nobody has called...
hi, av got an gas fire for repair which i mentioned before that pilot dosen't come on or comes on after a while but it now seems a spark problem thats causing it? sometimes it sparks sometimes it doesn't. it has piezo ignition and thermo electric. any ideas? will be appreciated.
been out a few times to fix boiler, started off with no ignition, ive changed venturi cleared probes and fitted new thermistors, now it fires. lasts about 10 seconds then locks out, this happens on both ch or dhw. the ignition spark continues to spark for 10 seconds even when burners lit. im...

So far I have tried the following:
