I've setup and run the generator. It works great with both gasoline and propane, but I haven't had to use it for an emergency, yet. The model HO7552 is a bit loud but tolerable. My order from Factory Pure included other items, as well as the generator. The shipment tracker worked great for the other items, but I received no shipping information about the generator. The shipping company had to try 3 times to deliver it because it's so heavy, it needed a lift gate. No one ever called me to ask if I would be home. Only after I called them and arranged a specific time and day were they able to deliver the generator. Poor communication on the part of the shipper. The second problem had to do with the generator serial number. The generator that I purchased was refurbished. It turns out that the factory removes the original serial number from the unit, and replaces it with a different one. The attached photo shows the view where the SN label should be attached to the lower level on the gas tank. It's not there! There was no communication from anyone at Factory Pure about this significant detail. Consequently, it took me a week to track down where they attached the new serial number, and who was responsible for warranty service based on that number. None of these details were sent to me in the original documentation, and the Factory Pure sale staff knew nothing, even though I had purchased an additional 3 year service warranty. Their service dept. eventually got me the answers, but they need much improvement, so I only give them 3 stars.
Everything was exactly as planned and promised. I am very satisfied!
When I received the generator it had been damaged in shipping. It is dual fuel propane and gas. When I got it home it would not run on propane. Spoke with tech support at Firman for a couple of hours and they were going to sell me a new regulator for the propane hook up. I fixed it myself. The controls for the regulator had been wired wrong.
Does great job. Does what I bought it for.
