Chaffoteaux Challenger 30ff Fault codes & diagnostics

No fault code table in its manual

We've read the 2 manuals we hold for the Chaffoteaux Challenger 30ff, and none has a fault code table, so there are no codes to list. We don't fill the gap with codes from a similar boiler, because the same code can mean something different on another model. The fault code table in the installation manual is the one to trust.
