Nest wiring for a new Worcester heatslave 11 combi 18-25 3amp nest 5amp boiler

[RayPlumb]

Replacing a clients old standard boiler with new oil heatslave 11 combi 18-25. It has a nest wired in and looking on the instructions it says 3amp max to nest but the boiler requests 5amp. Anyone with suggestion around this. Im sure there are plenty nests wired in to oil boilers.
Thanks

would the oil boiler work of a 3 amp fuse..

The heatslave will work off a 3 amp.

Can't see a boiler drawing over 3 amps, just downrate fuse, qualified sparky by the way

So you're a qualified sparky Richard? I knew there was more to you lol. Like above downrate fuse and bring boiler on, if 3 amp fuse melts you know the boiler draws more current and the nest isn't suitable. The fuse will protect the nest.

I have my boiler on a hive controller sitting on a 3A fuse in conjunction with the boiler, it's fine

If the 3amp melts. (I doubt it will) then put a 5amp back in for the boiler and cut in a 13amp fused spur into the supply cable to the nest and replace the 13amp fuse with a 3amp.
