Sorry folks but that should read Vaillant turbomax 828


IIRC the pilot is electric ignition? It's quite a new model.

It also has a built-in filling loop, have you checked this one isn't

Earlier models had just one filling valve but later models have two
which both need to be operated to allow water in.
