Powermax 185 - Whistle

As a matter of interest why would you replace the gas valve rather than resetting the adjustments?

Or why an expensive replacement rather than a cheap adjustment?

A valid point, but BG are unable to even service the boiler correctly what chance of them being able to adjust the gas valve? If he is on one of the fix everything contracts it won't cost him anything to change it.
 
Bg are still unable to alter the mix ratio on either the original or replacement valves, although they can replace the gas valve with the new model which is preset and apparantly needs no alteration.
 
Yes but why are BG "unable" to reset a gas valve?

They were also unable to identify a wrongly assembled and "At Risk" flue for the two years they were maintaining it and issuing the gas Safety certificates! When I pointed the fault out to the owner today she said that she had thought the lady who installed it was a cowboy!

great to see everyone has an opinion on this
the following is more likely to be the correct diagnosis (i speak from experience)

first these units are serviced correctly very rarely
secondly the burner gasket has to be replaced EVERYTIME it is serviced on several occasssions the new gaskets have not sealed correctly and the noise is air being sucked in to the burner chamber
the BG idiots don't know what they are doing with these units if they are sticking a tube in the top!, the flue gas analyser point is in the bottom of these units!

the most common problem with these is the prat who installed them putting the pump in the front at the bottom in the space that is needed to be able to remove the bottom plate for servicing

to service these properly both top ( Burner ) and bottom debris plate should be taken out then the flutes should be withdrawn and cleaned
the tubes are then swept with a small round brush and the whole unit reassembled
time - should take a competant engineer 45 to 50 minutes to do it properly
 
And how long do you think it should take a British Gas engineer then?

i would just like to point out that this doesnt have to be done every year but every other year as per manafacturers instructions as there is service schedule 1 (easy one) or schedule 2 (hard one) this does fall down on the fact that you dont normally know what the bloke did the year before you were there :confused:
 
i agree with gaz, but the whistling problem is easy to fix it is an adjustment on the gas valve. the air gas ratio is wrong
 
Yes, the fix is easy but the problem is that ( as written above ) all the BG guys are apparently not allowed to increase the gas mix or even touch the gas valve at all apart from replacing it!

"Independents rule" !

From the BBC News item:
Mr Harrison said Ms Pinkney's boiler displayed a number of faults and that the gas valve had been adjusted, preventing it from locking out

I wonder how you 'adjust' a gas valve so that the boiler won't lock out. (With a hammer, judging by the other comments!) And what would lockouts have to do with a fluegas leak? Unless we're talking about the condensing Powermax which presumably has a flue temperature sensor.... Seems unlikely. As usual, garbled reporting.

But if ever there was a message in this, I suggest it's Call a CORGI that actually knows what they're doing, and never DIY. This also calls into question whether BG's arrangements leave BG techs adequately trained....

Mike Harrison, a principal inspector for the HSE, said Ms Pinkney's boiler was not common but her particular model had been installed into new builds in the late 1990s.

The Range Powermax model I'd suspect, rather than the later Potterton badged HE condensing model. I wonder what the actual fault(s) were?

But she thought she HAD called a CORGI technician who knew what he was doing. Their adverts, telling everyone how wonderful they are, are all over ITV. How could she have known the difference between a competent technician and a cant?

She DIDN'T DIY. And she wound up dead. How much worse could it have been if she had tried to DIY it?

The moral of the story is don't trust them, get the manual, find out enough to be capable of doing it yourself and , if in doubt, turn it off.

The service engineers were given "general training" rather than for the boiler itself, he said.

BG should have realised they weren't sufficiently competent and called a specialist.

And, when you CORGI RGIs are blatting on about how dangerous DIY gas work is, can we clearly mark this one down as an avoidable and tragic accident to which RGIs had been repeatedly summoned and which they had failed to avert.

The problem is incompetent gas work; it is not necessarily DIY gas work.
 
Yesterday, I went to a boiler which had been inspected by BG who issued a printed statement on it which included that the flue was OK.

An independent RGI later issued an LSC confirming that everything was fine.

I immediately identified when I made my initial assessment of the boiler installation that the flue was wrongly assembled and would be classed as "At Risk".

I have advised the landlord to complain to BG and expect them to correct the defect. If he gets any problem then I have advised him how to complain to CORGI.

The RGI, who used to post at Gas-News is another aspect and I will just give him some advice but since BG advertise in a way that implies that their engineers are highly trained I have no sympathy for them.
