Review: Great Generate Bang For The Buck! - This generator is fantastic. After installing my solar system and wanting to hook up a generator to a manual transfer box, I researched all the dual fuel generators I could find and found this one to be the biggest bang for the buck. I had some questions when I first got my generator and contacted Firman who is located in Arizona. They were extremely responsive on email and also answered the phone. Yes, you can get a human to talk to at the company which is amazing these days with everyone dumping phone service for chat and email. The generate runs a solid 13 hours on a full 20lb tank of propane and equally as long with a full tank of gas. Unpacking and putting together the wheels and tow bar were super easy. They give you all the tools you need to do it meaning you don't have to pull out your toolbox to get this all set up. Starting this was so easy. Press button start fired up IMMEDIATELY on both gas and propane. TIP: When it fires up, immediately move the choke to the running position as you only need the choke for literally the first few seconds and that's it. This runs very clean at 60hz solid on the display and I have had no fluctuations. This really cranks out the power and had all the plugs you would need for just about any type of hookup. I am using the 30amp twist lock to connect to the house. The noise level is at a level where you don't have to wear ear plugs and you can talk to someone around you when it's running but it's not "quiet". However, I cannot hear it running when inside my house and neither can my neighbor so it's a win win!s
Review: Leaked Oil and Horrible customer support! - My generator started leaking oil from the crank case gasket after only one use (basically I tested it in my garage – then stored it). I called warranty/tech support – the rep  seemed friendly and helpful. He asked me to email him some pictures of the problem, which I promptly did that same day. Four weeks passed with no response. I emailed twice asking for an update – again no response. After six weeks I called back – I was told that that the support analyst who helped me the first time would call me back that day. Guess what? He didn’t call me back. A week later I try again – after waiting on hold for several minutes they inform me that I will have to take the unit to local shop for repair. I have to take the 240 pound generator that is leaking oil to the shop myself – at my own expense. Ok I say, which repair shop? The first one they name is 40 miles from my house. The rep  said he will find a closer repair facility and contact me when the work order is approved. Guess what – that was two weeks ago. I’ve emailed twice and gotten zero response. Firman customer support: you FAILED.

## Questions & Answers

**Q: Assume this is a bonded neutral unit. Can this bond be removed? If so, are there redily available instructions?**
A: i have no idea what you are talking about. please call firman for the asnswer. sorry.

**Q: What's the horse power when running on gas?**
A: I’ve never seen a hp rating but that’s irrelevant. The output doesn’t change between fuels and it started right up on both fuels and no issues. I believe it’s 425cc I run it on non ethanol fuel only. It requires only 87. That being said I’m going to guess in the 20’s the larger one uses same engine. So this may be overpowered for its output. But that’s just a guess

**Q: what is volt-lock?**
A: The FIRMAN Volt Lock automatic voltage regulator ensures clean, consistent power output from the FIRMAN Power Stream alternator.

**Q: Does the generator have a manual start?**
A: Yes, electric and manual pull

### ⭐⭐⭐⭐⭐ Runs whole house
*by S***D on February 2, 2020*

Easy to assemble. Starts easily on propane with half choke. I use it to backfeed my spa power feed #6 wire into my distribution panel. I installed a 30 Amp 240 volt outdoor receptacle that feeds into the spa breaker panel. I can run the spa 6KW heaters plus one 2KW pump at the same time. The heaters only go on momentarily but the generator does not stall. I installed a Reliance double wattmeter next to my home distribution panel. The CT doughnuts fit easily over the #6 wires. Running off the generator , I’m only pulling 1KW with my refrigerator, freezer, gas furnace and wine cellar on. Microwave pulls 2KW. TVs and electronics work perfectly. I have a gas water heater and gas dryer. Oven is 2KW. It is clear that 5700 Watts continuous power will be plenty to run my entire house in the winter with no problem. Generator is 150 ft from the house so I hardly hear it. When summer comes, I’ll try the AC, but we rarely use it in Northern California. Sorry for the long review but I answered many questions I had about the generator. Addition: I installed a Sure Start soft start in my 3.5 ton AC unit. The generator now can start and run my AC unit and the entire house.
