Boulter (OIL) boiler not firing

[Mike2007]

For your info;
NORMAL
1. All time controls, thermostats and safety switches made and call for heat.
2. Motor and ignition on (oil and air). Pumping oil and sparking.
3. Solenoid valve opens. (Black object on top of little pump, releases pressurised oil)
4. Oil sprays and is ignited by spark, flame.
5. Photo-cell probe reacts to flame brightness, turns off ignition (spark)
6. Run position.
7. Runs until heating requirement is satisfied via thermostats.

NO FLAME
1. Thermostats call for heat.
2. Motor-fan-pump and ignition on.
3. Solenoid valve opens for oil.
4. No flame?
5. Photo-cell sees no light and reacts
6. Switches motor-ignition-solenoid off.
7. Box at lock out, light on.
8. Sequence can be tried again after lock out time has passed.

You obviously have no idea how a Riello burner works!!!

I would suggest that you save your comments until until you have something relavent to add to the thread !!

Solenoid closes on Riello and spark doesn't happen until ignition phase. If the burner does not attempt ignition burner will circulate oil at wash pressure (solenoid open) without lockout.

I was giving general information to the question as they were unsure of the oil burner operation. I did not read that it was Riello. But saying that, I would say you are a bit of a control freak in trying to dismiss other posters comments....take a CHILL pill hot head!

I thought some control boxes checked the photocell (for dark resistance) in the early stages of the ignition process as a fail safe?

Not an expert on oil burners but have this recollection?

How can it be usefull general information if you have not taken the trouble to read the post, your information was irrelavent!!

How does it make me a " control freak" I only pointed out that you were talking cr*p!!

ps: which manual did you get your information from??

Yes they do to ensure there is no flame before oilrelease/ignition!!

THanks to you all.

Thought you might like to know the answer. The engineer replaced the phtocell first...no joy. Then he replaced the control unit still no joy. After phoning a few others in the trade it turned out to be the solenoid.

After changing this...hooray....heating again.

He said he had not come across this fault in 15 years, adding that "in this job you're always learning"...so I thought it might be worth passing on.


Thanks again for all you great comments and advice.

Cheers

Peter

You are full of crap mate and let down a good forum. Crawl back under stone you came from! There some top guys on this site and you ain't one of them!

 

[Robert too]

we had a similar problem , on a Boulter unit.

Our fault was the control box
