burner pressures

[mickie]

if its a 24kw boiler and you get that gas rating it and the fga checks out ok ? why then do you need to do burner pressure ?

 

[AWheating]

so you are assuming that the person who fitted the boiler in the first place did so correctly? personally i would assume nothing.

 

[mickie]

its around 10mb for 24kw boilers aint it ?

 

[mickie]

no? i just did a gas rate

 

[AWheating]

all appliances are different

I had one today Worcester 240 RSF. Screw for burner pressure wouldn't turn and as I have a habbit of snapping screws I was reluctant to force this one. No MI, I'm sure the boiler is a 24kw but the heat input is 30kw for DHW. Gas Rated this at 29kw, FGA 0.0007. Working pressure. Seals, flame picture and burner insulation all good. I had a cooker and a boiler it took me 1.5 hours is that normal for a landlord certificate 2 appliances. Or am I just slow?

Guessing/assuming is not good enough as far as I am concerned. Off top of my head a Worc. 24 CDI BP is 13mbar to name but one.

Ideally,(although rarely carried out) it is good practice to do BP & Gas Rate where possible. How do you know the correct injector is in place otherwise. It is possible to have an LPG nozzle not been swapped for a gas one or vise-versa. Doing a Gas Rate and BP would indicate this as the readings would not tally up.


As others mentioned, unless you know the appliance settings, in the absence of a data plate, MI's or info from manufacturer you should not be carrying out any work on the appliance. Simple as that.

no your slow.lol.
and i agree with kirk,

1.5 hours for cooker and boiler , took me about hour and quarter to do each boiler service today not sure if thats slow but then i'm usually install. As far as i'm concerned working with gas isn't a race rather take my time and double check again if not sure .

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.

ive seen lpg water heater connected to natural gas
