Bought this heater out of curiousity after seeing them on Youtube. Very easy to set up and get started. I did have to add two small pieces of 2x4 to the feet to give enough space for the exhaust pipe to bend out from underneath the unit. I successfully powered it for the first hour of testing with a 12V car jumper pack just to test it initially, but purchased a 110v to 12v power supply off of Amazon for $18 to power it permanently. Basically take it out of the box, screw two 2x4s to the feet, attach the exhaust and intake hoses, pour in the diesel fuel, press the power button, press and hold the two arrows on controller simultaneously for 10 seconds or so to initially prime the pump, set the thermostat to your liking and you are up and going. I set mine in the window sill of my garage and made a pass through for the exhaust out of a 2x8 with a 2 1/2" hole cut out and screwed two 6x6" pieces of sheet metal on either side with a 1 1/2" hole cut out for the exhaust pipe to pass through. There are a lot of Youtube and Facebook experts that advise you to mess with the settings, but I test ran the unit for 5 days and nights on the highest setting during the recent cold snap right out of the box with zero issues. Pump and fan were both much quieter than I expected after hearing people complain about it on Youtube. I am really impressed with how much heat it produces on such a small amount of fuel all while exhausting the fumes outdoors. Long story short, ignore the noise on Youtube and run it the way Vevor tells you to and you've got an amazing little heater for emergencies or supplimental heating of your smaller spaces. Highly recommend.
