Ideal Classic burner box seal

[jtsplumbing]

I'm not sure what was done, but with the the case on I would have put the analyser in the flue gas & air intake, if there both okay I would have left it?

But that's the point that I am trying to make, these boilers are meant to be checked only on working & burner pressure, flame picture, FGA on these old units is surely irrelevant as no data is given for FGA readings

Using a FGA on any appliance isn't going to hurt, even old open flue appliances, but as an extra not in place of a proper service. And there is a point on top of a Classic to connect your analyser to.

There are set limits for appliances where no manufacturer data for specifics exist. Normally 0.004 ratio but can be different in certain circumstances.

I did use my FGA, as I stated earlier, on the room test setting, with the casing off. This was because there was a piece of the rope seal that was missing and, on further inspection I had noticed that the rest of the seal had crumbled to dust, more or less.
As I don't want to be responsible for the demise of any person, for whatever cause, I decided to check for CO emissions and found that there was a considerable amount of CO being emitted from the area where the seal had deteriorated. I told the customer and, as previously stated, they were happy for me to switch off the gas supply and to get the seal replaced when I could.
The seal was subsequently replaced, the CO level was checked again, and there was no evidence of any CO leak following the replacement of the seal, so the boiler case was put can and I have now arranged with the customer to carry out a 'Proper' service in the next couple of days.

Aquazone - I thought that the level for a gas boiler was 0.0008, at least that's what I was taught anyway 🙂

you will be forever trying to look for a fault thats not there at 0.0008.
(CO level less than or equal to 350ppm and Combustion Ratio less than or equal to 0.0040) is deemed safe. but always refer to MI's

i personally think less than 0.0080 is way too high and would try to get better readings.

You got one 0 to meny for the action level 0.008 for boilers.

I thought it was 0.0040, but if strip cleaned then 0.008 is allowed. I am due my ACS renewal soon so thats off top my head from 4 years ago.

Tbh I've never had to leave one at such a high reading, I think you can always find the root cause if you strip it down (providing the flues not holed/seals gone

Have read of TB 126 & BS7967: 2015.
Some changes in last year or so.
As always MI's trumps standards for your action levels.
