Frost protection on combi boiler

[davesparks]

I can help the OP there, according to WB technical, only the CDI Regular hasn't internal frost protection.

But perhaps get a competent gas certified installer to read the instructions instead.

Well they could do with mentioning it in their installation instructions then, Somme of them mention it on the first couple of pages and others don't.
