Perhaps he could have shown the how to improve the turndown ratio? After all, it's a premix burner. Imagine what he could achieve with that when he gets 10:1 on an atmospheric?
You being one of them.I think that Ideal are the only manufacturer who don't want RGIs to adjust their gas valves. Presumably thinking some don't know what they are doing?
Asked for permission??I had a similar problem on an early Isar and asked for permission to adjust it.

Do Vaillant know that you are now working for Ideal?They did the tweak and vowed to have the auto test at the factory changed. Apparently it only tested it on full power and "that it modulated". But not that it stayed alight at min power!
The mere mention of your name to a manufacturer seems to reward you with preferential treatment.and sent their design team engineer as well as some kind of regional engineer.

why did they decide to send their design engineer to your jobI had a similar problem on an early Isar and asked for permission to adjust it but they would not agree and sent their design team engineer as well as some kind of regional engineer.
why would they vow to have an auto test just because of one/your problematic gas valve ?They did the tweak and vowed to have the auto test at the factory changed

Hello MeldrewsIt seems you are a victim of what I call a 'car mechanic' repair, that is 'keep replacing things until it works again'. Usually only one item fails at any time, the skill is to find and cure that fault to get the boiler working again, beyond that it may be advisable to replace worn or substandard parts to bring performance back to an acceptable level. I agree with Muggles, at this stage, and to avoid protracted expense, call Ideal to arrange a proper diagnosis and repair.
An important part of fault diagnosis is to isolate the opinion from the fact, so please answer the following questions:-
1. Does the boiler fire each time it calls for heat? How do you know it has fired?
2. Does the 'c' symbol appear in the display when heating is called for and the room thermostat is turned up high?
3. Does the blue light illuminate seconds after the ignition process starts?
4. Does the blue light stay on?
5. Do all the radiators get hot before the boiler shuts the flame off? (clearly all/any TRVs should be set to max for this test)
6. Feel the boiler primary pipework, is the RHS pipe hotter than the LHS, and is there between 10C and 20C temperature difference between them?
7. Is the boiler temperature knob set to 'e' or thereabouts?
