Firebird - black smoke & fumes

karltimber

Hi,
Have a 5 year old Firebird 90S internal oil boiler with a rdb reillo unit on it.

Recently it started to smell the utility room and then started to give out black smoke out of the flue.
I serviced it - cleaned baffles & replaced nozzle and it was ok-ish.
Black smoke was only half as bad.
I took down the air settings (3) and adjusted to allow more air (3.5) and the smoke had gone but it is still fuming into the utility room - a bad smell.

so, I need to get someone to look at it.
But who, will my plumber be up to the job or do I need someone with more precise knowledge - who can do a co2 test afterwards and make sure it's burning correctly.
Don't want to throw money after bad.

any ideas ??
Not sure what could be causing it.

You need a trained boiler service engineer.#
See OFTEC site... oftec.org/ireland.asp
Unlike Gas you don't legally have to be registered but you should be trained and proven to be "Competent Person". You don't have to be OFTEC registered to service but it's a starting point.

The nozel may have looked clean but should be replaced on every service.
The air can only be accuratly adjusted with the use of an electronic analyser which measures CO. CO2 and air mix from your flue.

thx ntpm,

I changed the nozzle to a new one alright.

I adjusted the air just to try and get rid of the smoke - as a forum stated that a smoky flue outlet meant that there was not enough air for the mix. I know the orig setting - for when it gets fixed.

I need to be causious as it's carbon monoxide that the smell is - so will look at the website and ring them friday.
The plumber that installed it - not sure if he can really 100% say it's fixed - don't know. And would like to get it setup -ie co2 reading - to make sure it is burning effciently.

got a new fill lately - wonder if one (tank & boiler) of the filters got very dirty and is stopping flow.

the original plumber may be able tocheck oil pressure, analyse and set up boiler again, not a big job. If not ring round boiler service engineers.
You can't smell Carbon Monoxide ( silent killer) that is why you might want to get a CO monitor.
Re filters: if filters in fuel line was blocked the oil pressure would be effected and the burner would probably go into" lock out". red light on front of burner goes on and you have to reset it manually.

Flue in boiler casing may need resealing and gasket checked. Thats why you might be getting smells.
