Hello, I will help you on your question.

I am researching this model for information. While I am perhaps you can respond to these questions which will guide my response:

Has the fire Marshall cited particular clearances for this product?

Has he cited a particular code? (Typically, municipalities have adopted one of 2 codes, and maybe one of several revisions of each.)

Technically, I can answer your question without this information, but it will allow a more in depth response.

I need to know what the specifications are for an ONAN Generator, model no. DSHAC5789092 that the manufacturer requires for clearances. This should be stated in the installation manual or owners manual, neither of which we can seem to locate.
I need a copy of this to satisy the Fire Marshal.
Expert:  staircaseman replied 1 year ago.

Yes, I find nothing for that number either. Perhaps there is a back door to this.

Can you tell me the horsepower of the engine, and the voltage and wattage output?

Customer: replied 1 year ago.
I've verified the model number that I gave you. I was also able to locate the serial number: B070 019 355
Expert:  staircaseman replied 1 year ago.

Unfortunately, these numbers bring up nothing on searches by 2 different search engines.

Sometimes manufacturers will rework their numbers to reflect changes in their systems. Usually, they will catalog changed numbers with the new ones and a search will take you there. But that doesn't seem to be happening here.

The other information that I asked for might help me circumvent these problems.

Thank you for checking, and I asked for is the manufacturers specs -not to interpet building codes.
Expert:  staircaseman replied 1 year ago.

Sometimes the situational facts can guide our answers. I will open this back to other experts. Maybe they can help.

Best wishes for your problem.
