burner pressures

[gaspastemania]

Been lumped onto servicing which normally dont do so can someone clarify what burner pressures i should be getting please for 24 to 28 kw boilers.

Depends on boiler make and model. You need to refer to the data badge and check it accordingly.

 

[gaspastemania]

sorry should have been bit more clearer, working on social housing lack of MI's as usual and have come across occasional appliance in past where data tag is a mess, what occurs in then?

 

[Blake]

I normally ring the manufacturers tech line and ask for the info. Flame pic will give you an indication, as will FGA readings, but Ideally you need to know what they should be in order to check them and adjust accordingly

 

[gaspastemania]

would be right in thinking a gas rate be good indicator as well?

 

[Blake]

Yeah in theory, but if it has no data badge, how do you know the figure you get is actually what it should be? It's a pain when the data badge has been ripped off, I have a little netbook that I've loaded on several thousand manuals so I can get the info I need without having to ring manufacturers.

Yeah i do the same with a net book, i keep it in the bag that came with my kane analyser, and house my multimeter in their as well.

no data badge, no MI = NO SERVICE, unless you have absolute clear product knowledge, as you cannot confirm you have enough info to confirm appliance safety, a bit OTT i agree, but when the big bad man asks you why you thought you could do these checks on an appliance you do not know, you will be in soapy

 

[AWheating]

if there is no data badge then how do you even know the basics like if the appliance is for natural gas/lpg? im with kirkgas.

 

[Blake]

Well if there is a gas meter with pipework leading from it to the boiler, I'm happy to assume its Natural gas. If the boiler case states "Joe Bloggs 24 cdi" for example, I will then ring the "joe Bloggs" tech line and confirm the appliance and ask for the burner pressures which I will then check and adjust accordingly. Simples.
