Need install instructions or dealer names for necchi and campiglio wood boiler

Can anyone help me get my client's necchi and campiglio boiler installed correctly. He bought it used (though it looks totally untouched to me) four years ago, he has no paperwork for it. Plumbing Code requires it be installed "according to manufacturer's instructions". I'd like best to contact the importer or a dealer in the northeast. Failing that maybe another owner who could copy their install paper work. I tried googling necchi and campiglio and this site is the best of only six items three of which were in russian or japanese!

Is that a coal or wood-fired boiler?
