Q: I'm looking at your 7kw Generac and the add says 7kw but the features info show 6kw? The Briggs specs say it can be placed as close as 18 to the house and I read from a customer the composite cover of the Generac has to be 5 feet away? Can you clarify for me?
by Nick Gianacoplos from Connecticut on July 23, 2013

A: The wattage output change is based on the fuel type you would be using. When using Natural Gas all generators have a wattage drop. The Generac CorePower unit outputs 7kW when operating on LP Gas and 6kW when operating on NG.

The Briggs model does recommend a minimum of 18 inches since it has a steel enclosure and the Generac CorePower has a composite enclosure so 5 feet is required as a minimum. We recommend upgrading to the Briggs & Stratton 8kW if you plan on having the unit closer to the house since it has a steel enclosure.

Please keep in mind that local code can supersede the distance on any generator so you must check with your local inspector or AHJ (Authority Having Jurisdiction) for your local code requirements.

This new 2013 model Briggs & Stratton Home Standby generator system brings together some really great features from Briggs. This is the smallest footprint home standby on the market that meets NFP standards to be within 18 inches of your home, assuming your local code allows for this. This machine also comes with the galvanneal steel enclosure that is similar to what is used on cars. This prevents rust and is not something you are going to find on the competitors models.
