Ideal Classic burner box seal

[Robert Tyrrell]

Yeah - I suppose it's my fault really, should have done a bit more checking first.
The company is a good one, it's just that they told me it'd be a one day thing so that's what I allowed in my work schedule and now I find that I need another day, which I'm not happy about tbh.
As for the info - yep, they give you all you need - supposedly but there was a guy doing a re-sit who'd been doing it for years and he couldn't find the answers to some of the questions. There wasn't an option for the days training just ½ day reading etc and ½ day exams/practical. How they can justify telling me that it 'can be done' in a day is beyond me. In order to do that you'd need encyclopaedic knowledge of the standards, and the ability to recall any part of them at will.
I only spent around 15 minutes doing the practical as I sailed through but the paperwork side (exams) is a nightmare so if I can, I'd like to read up stuff beforehand.

You will just overload your head with stuff you don't need, the way the training books that we are given cover most of the answers and they are very well designed by the instructor so its a pice of cake to find the answers, seems your not getting the best experience from where your doing the training, maybe look in our area next time wont be half as stressful.

I was using the FGA on the room test setting yes, but I was picking up CO at the back of the burner box where the seal looked as though it was missing. I know that there's a casing over the whole thing but I didn't want to take chances with it as it should be a complete seal.
My customers were very happy that I'd spotted the missing part of the seal, and to have the boiler off until I'd fixed it, which will be in the morning as I'm doing my LPG assessment today.

So you were doing a room CO test on a room sealed boiler, with the case off?

did the conversion 4 or 5 years back, did the day training, waste of tap and sat the exams, just read the books or notes for the answers, they are all there, if I can pass, a monkey can pilot a space shuttle, its that easy 🙂

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 🙂

 

[Gasmk1]

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.

 

[Aquazone]

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.
