Got mine installed and did not have the hinge rear to drop access to the wire hookup area. Simple install to the garage ceiling with a pilot hole for a 2" long, 1/4 in width wood hex head with nice big flat washers to support the single center attachment point to the garage ceiling. Ezy pzy and plenty secure. I wanted to be able to turn the fan direction if wanted.Ran 10 ga 2 wire with ground to it from the QUALITY dryer plug bought here at the Zon, and wired the unit. I set on heat level #2 and turned it on.Excellent HOT heat coming out, and 12 feet away the fan is clearly doing it's job. The fan power is fine, the heat is HOT just set on 2, and the only potential drawback for some is the thermostat is not as accurate in function as your whole house furnace is. Who cares?Most are using this for a garage or shop, and some don't want those to drop under freezing when unattended and unused. I set up a remote temp sensor and in a 12 x 25 ft garage, in Omaha NE and if you want to keep your garage above freezing, this unit can do that. Really, it can do that not working very hard.I was thinking this was a big toy, might help a little or might not. I was wrong. This is a serious tool, well made, works, hot heat and fan plenty strong - and all at $109? Are you kidding me??Can see other uses for this heater, too. This is NOT a toy, works, HOT heat, good fan, makes a bit of mild fan noise but WHO CARES? You sleeping in your garage?I got the ex warranty so if this goes South I'm covered, but by any account this is a nice unit, works, built solidly and if you do your own wiring be SAFE and be SURE to use a GOOD dryer plug with a lot of surface contact to your 10 ga wire. Critical. Tight and solid good connections is important. Get your gas cans out of your garage and into the shed.Read directions and adhere to them. They're there for a reason. My garage ceiling is only 7" but I attached this as high as I could right to the ceiling joists, center factory attachment point with big flat washers to help support.VERY impressive heater at this price point!!! Nice. My only nitpick is they should have made the ground attachment point the same as the two positives, with easy secure attachment. I used the extra wide wire crimper tool to secure a yellow 10ga wire loop to the end of the ground wire, then attached that to the ground point on the unit where they supplied the hex head bolt attachment. Works fine. Just UN-necessary and their trying to maximize profit by saving a buck a copy. No bid deal. GOOD UNIT.PS: The Zon 10 ga 2 wire and one ground wire pricing was way better than the big store big name hardware stores here!!
