High levels of CO outside - Boiler shut down

Gigs, I am referring to checking gas contents incoming into the chamber that could be contaminated by exhaust fumes due to failed seal or dislocated inner tube

Doing FGA checks on such boilers is left to person dealing with the boiler. The boiler does not have a test point, so makers are not expecting you to FGA the exhaust (attended a call where over zealous 'engineer' disconnected a boiler and rcomnded replacement- boiler was reinstated after Gas Saf got involved)

Laura, high CO reading means there is insufficient oxygen available for combustion process. A service may be all that is required. Cannot see the reasoning for new boiler based on FGA analysis alone

Hi,
I'm looking for some advice please.
I have a Baxi boiler (solo, I think) that was installed 9 years ago. Its been running fine but I hadn't had it serviced for a few years so I called a local firm last week to carry out a service just for peace of mind. The young guy that turned up took the front off, remarked at how clean it all was, said everything was clear and it all looked perfect and was working perfectly etc...until he took a meter reading outside that said there were dangerous levels of CO. He said he couldn't understand why he was getting the reading and would have to shut it down. He confirmed there was no leak of CO in the house. The following day his boss rang me and said he'd send another engineer round to have a look. I would have liked someone with experience but a young lad just out of college arrived. He did the same test and announced 10 mins later that my only option was a new boiler.
Fair enough if the boiler is faulty I need a new boiler but the fact that they can't give me a reason for why Im getting the high reading is troubling me when by their own words it all looks clean and clear and in perfect working order. If I'd called them out because it wasn't working properly I could also understand. Its only 9 years old, has been working perfectly (or so it seemed) and I have no CO leakage in the house.
Does anyone have any advice as to what could be causing the problem please as they cannot answer my question? I would just like more information before I part with a lot of money that I don't have.
Thank you in advance.

What were the recorded readings?
 
Neither of them gave me the actual readings. They just said they'd never seen readings so high.
Its still turned off now. I have called another engineer who specialises in Baxi's, he can't come for a few days but I'd rather wait for him then have these 2 back. I'll let you know what happens!
 
Laura, no one except Gas Transporter has automatic power to disconnect your appliance. We all have to be given permission to disconnect and make safe.

You may want to talk with Gas Safe. The inspector may well come out and verify that there is a problem. If there is no problem, then the 'engineer' may well be 'spoken to' for giving good RGIs a bad name ;)

Tony, take it you are not going to share words of wisdom with me regards testing of inlet air on the Solo then?

Well Danny, you look at the service manual for the test point and pretend to be British Gas personal.

Danny I think he means the above load of tripe that he wrote.
No surprise telly "top100" tony manages to insinuate he'd always do a test that isn't pratically possible.

Tony there is no test point to test combution air
There is no test point to test flue gases either

Which manual are you referring to Tony?
 
No test point for flue gases.

But there is the test point to the inlet air ! Not labelled as such though!

Baxi Solo3 has a FGA test point under the rubber plug on the front of the chamber. If you wanted to check the incoming air you could possibly access the chamber via the same test point...with the help of blutac to seal.

With a rear flue it's easy to check flue integrity from the chamber.

Thank you Gasguru. Very informative as always

I had forgotten about that rubber bung :oops:
