I am going to order a Generac Core Power (5837) to replace my 6KW portable unit.

Two questions:

1. I found a document from Generac regarding NFPA-37. This document indicates that ALL units can now be installed 18" from the wall. I have 96" to closest opening (garage door) and no windows on the wall where the unit will be located. Wall is brick, so fire rating is good. I was hoping to install the unit 24" from the wall.
Does the NFPA-37 document apply to this unit since it is composit housing?

2. Can I use a small inexpensive Air Conditioning disconnect on the outer wall.

Thanks,

.

You can always locate a generator further from a building than NFPA-37 calls for as a minimum.

Skip,

I plan on keeping it at 24" if OK by code. My concern was that the code might not apply to this unit, and I would have to increase the clearance.

You need to contact your local inspector. You may have amendments to code that will differ. Also the 18" Generac claims for installation has been disallowed by some states because the testing wasn't done by a recognized testing lab and Generac would not publish the results.

Yes, you can use a 60amp non-fuseable A/C disconnect.

CEB_58,
Thanks for that info.

I have talked to the inpector, and he will follow the manufacturers recommendations.
The inspector did not require a disconnect, but I will install one anyway.

Just need to get electrical and gas permits.

Have a nice weekend.

I believe the core power has to be five feet from the building.

I am going to play it safe and install mine 5 feet from my home. Better than having a go around with the inspector once it is all finished.

where you are located

It would make it easier if every one posted where they are at. I have heard from elect. in NJ who went by NFPA 37 and placed them at 5 ft' just to have a fight with other setback amendments and have to go through the process of getting a variance so they didn't have to tear every thing out and start over again.
This is something that needs clearing up before the install starts.

The installation manual shows minimum 36" from the wall, NFPA-37 indicates 60", Generac's NFPA-37 document indicated minimum 18".

My inspector will go with the manufacturers recommendation, so I guess it will be 36" in my case.
