That is the point.Do the boiler manufacturers state that it doesn't need a 3A fuse in other countries?
In (most) other countries they don't have 3A fuses so they probably don't.

Yes, and that identifies the various regulations which will, or may, apply to the installation of that boiler. That various regulations will apply is not in doubt.
Did you ask them if they differ in internal protection in ways which make the ones in this country unsafe to use on a supply fused at > 3A?WB say as far as they are aware, there is nothing in the regulations (gas or electricity) that requires a limit on fusing to 3A.
They say the boilers they manufacture for markets outside the UK are not the same as those for this market.
In (most) other countries they don't have 3A fuses so they probably don't.
Do we know whether the product sold in France is identical to the one sold in the UK?Indeed! The manuals appear area specific. In the UK the Vaillant instructions say: .... Instead, the French version makes no mention of any fuse protection whatsoever, but is concerned instead about the boiler being plugged into an accessible, suitable outlet, and warns of the danger of fluctuating voltages
Well - thanks for doing that, and apologies if my earlier reply made me seen ungrateful.I have just been on the phone to the technical helplines at Worcester Bosch and Gas Safe.
And that puts an end to assertions that MIs are guidance only and don't have to be followed if they are wrong, when it comes to gas appliances.Gas Safe say ... that it is written into the gas regs that manufacturer's instructions MUST be followed.
I've emailed the question to Vaillant.Nope. If you'd like to have that discussion with them, their general enquiries number is 0330 123 9559 and their tech support is 0330 123 3366.
Typically the manuals have parts lists/diagrams in the back - the key thing to look at is the main PCB/electronics module and see if they have the same part number. If they have the same part number, then for the purposes of this discussion they are identical.Do we know whether the product sold in France is identical to the one sold in the UK?

AT LAST THIS HAS BEEN ACCEPTED!And that puts an end to assertions that MIs are guidance only and don't have to be followed if they are wrong, when it comes to gas appliances.
Not possible?No one has disputed that.
The questions have been "Is it really necessary?" and "How do they manage where this is not possible?"
