My plumber mate came round yesterday to do a boiler service on my Rapid 32.
I have an Intergas outside weather sensor also connected.
He installed it two years ago.
He's never worked on Intergas before and I'm not sure he wants to again. He wanted to take a look inside it anyway and perhaps learn something.
Measured 22mbar at the gas meter and 20mbar at the gas valve on the boiler.
I have to say the Intergas manual is a little vague. It basically says take off the casing and clean out heat exchanger but the expansion vessel weighs a ton and there is nowhere to really rest it.
So he calls Intergas and speaks them and they say it only needs cleaning out every 3 years and will need new gaskets.
So he proceeds with CO2 test. It's out of limits on High test. As it cannot be adjusted on high, we perform the low test. It's within limits for CO2 at 8.5%.
So we call Intergas again. They say turn it up to 9.1 which is the maximum %age for CO2 on LOW. This should result in 9.4% for CO2 on HIGH test. It was 8.2%!!!
According to the manual, O2 reading should reduce when CO2 is increased.
Bear in mind that it's never needed touching from factory so how can it be so out?
We call Intergas again. They say tweak it up to 9.1%. He does that and the CO2 on HIGH is still out of limits and the O2 is even worse at 6.4%. It should be a max of 5.6%.
So I call Intergas getting concerned that it seems to be out of spec and they say, "Well it could be down to atmospheric conditions, etc., etc.!"
Plumber mate purges his analyser, changes the filters and we do it all again. No change!
Call Intergas and they say "Tweak it up to 9.2%" so I say to them, "but that's out of limits according to the manual". Then they say "It doesn't matter."
Obviously, I'm a bit worried about any warranty issues. They said could come out and have a look for £90 but if it's found that there is a problem they will sort it at their cost.
I've already paid for a boiler service. I don't want to have to pay them. Likelihood is they would fudge the figures to warrant charging me I reckon.
Flame Efficiency at its original low reading was like 99.1% from memory. As soon as my mate started tweaking it, it dropped to 98%.
He's happy to come back and have another play but what is the best setting for it to get the best efficiency.
I don't suppose cleaning of the heat exchanger would have made any difference to the readings, would it? If so, I'll get him to order the gaskets in and do a full 3 year service.
Has anyone else noticed all the anomalies in the Rapid 32 manual in respect of Section Codes being all wrong?
I like things to be RIGHT!
