Boiler I. D. For high reading on analysers

[Matt0029]

I have to go to a boiler tomorrow that has been classed as I. D dangerous by another engineer. I haven't fully read the Cp12 they have been issued. Surely this means a C0/C02 ratio greater than 0.008. If it was between 0.004 and 0.007 the appliance would be at risk. Thanks for any input. Usually work on installs but starting to get in to land lord checks.

It might not just be the anyliser reading , it could be anything .

Depends on the appliance, if it’s an open flued boiler it would be I.D. If it’s a fan flue’d room sealed appliance it’s at risk.

Have a look at the GIUSP

I briefly saw a picture of the Cp12. It mentioned too high a reading when analysed. Though I could see any figures.

 

[Matt0029]

It's fan flue'd room sealed yes.

You really need to see it a make your own diagnosis but gather all the information you can and do another flue gas analysis and go from there. Kop

Thanks yes I go tomorrow.

If I do a full check of it. And get an acceptable reading, after stripping down and cleaning the burner if needed. And checking everything else needed to check when doing a Cp12 on a boiler. An engineer would be able to write a new Cp12 stating the appliance is safe to use?

Yes correct, check the case seals ive had em off the scale due to a failed seal take some with you just in case ? Kop

Are you going to give a second opinion or to try and repair?
