Valiant combination boiler - Mfg still exists?

Got called with problems on Valiant combination boiler -- atmospheric, circa mid-1990s -- first I've ever seen here in Colorado. Having intermittent control issue(s).

Owners have wiring schematic but it does not show internal relay switching -- so need better diagram, tried searching the web -- no luck -- I find Vaillant boilers (UK) and other variations on name (all mod/cons), but nothing like Valiant -- it uses an 3 way valve, standard Honeywell spark module, atmospheric burners.

Anyone know of these units? I suspect Mfg. is no longer in business.

Anyone that can confirm any of this, or point me to someone who has worked on them or rep them in the US ?

Thanks for response

    It's a huge company

    maybe one of the top 3 boiler manufacturers in the world.

    They still maintain an office, and some parts in NJ 856-786-2000.

    They have entered the US market again with their solar offerings, with an office in CA. With claims to be back with hydronic and geo offerings when the economy gets better?
