Rated 5 out of 5 by 8KW Generator I have such peace of mind with my Generac 8KW. It starts right up when the power is out. If it happens during the night, in the morning I don't even realize that my power is through the generator. March 19, 2015
Rated 4 out of 5 by Good unit, but did have some issues The product works well. It provides all the backup power I need. It takes over automatically, tests itself weekly. It was exactly what I wanted and it works.The issue I have had is that the weekly test cycle fails and after 6 months and finally 3 support visits the control board will be replaced tomorrow. Hopefully I will have no more issues after that. March 11, 2015
Rated 3 out of 5 by Content in a storm added a generator after hurricane sandy/nj - it is comforting knowing the generator will be there in a store - tiresome journey with my generator buy worth it in the long run - diane/nj/usa March 11, 2015
Rated 2 out of 5 by Original motor failed shortly after two year warranty. Costly replacement motor.. Hope the new one works for a long time. I purchased the 8kw with a two year warranty from my electrician. Shortly after two years the motor failed even though there was oil available. At a cost of $650 a new motor was installed and I have not had to use the generator. I was told that I have a new warranty.My fingers are crossed that it will last a long time with no more problems. February 2, 2015
Rated 5 out of 5 by great super engineering,this product will save my house from hurricanes with resultant flooding from loss of sump pump due to electricity outages February 2, 2015
Rated 5 out of 5 by Great peace of mind We have had our generator for about 18 months now. We lost power a few times during that period- once for 5 days. The generator gave us comfort and peace of mind. With two small kids, having lights, heat, full ability to prepare meals, and even watch DVDs during the power outage was a huge help. We felt very blessed to have power and invited our neighbors over to stay warm. The system will kick on in the event of power outage even when we are not home, giving us peace of mind that our sump pump will run and our basement will not flood. Worth the investment if you loose power often. January 16, 2015
Rated 4 out of 5 by great price, suburb installtion quiet operation this is a quality product..installation was quick and unit runs fine. January 7, 2015
Rated 5 out of 5 by 5 Stars Had the unit professionally installed in 2013.Works great, lost power 5 times in 2014, kicked on, ran for nearly 24 hours during one outage. Propane fueled unit. 8KW unit. December 17, 2014

Answer: 
We can determine the correct regulator for you. We will need to know the outlet pressure from your LP supply before we make that regulator suggestion. If you get that info, call Grainger's Techncial Product Support Team so we can get that regulator item number for you. 800 472 4643
