HELP Mr Heater Big Maxx

[almindigo]

So boss just gave me the 75000 btu big maxx. Plan on installing in garage. Wondering how to tell if it works. Do I have to completely install venting and hook up gas first? The green led is indicating pressure switch issue when I plug it in (nothing else installed/hooked up, just simply plugged in). New to all this. Any help appreciated. No call back from customer service yet.

Hypothetically I would probably just plug it in and try to get gas to it - flexible dryer or stove location.

It'll turn on/start up if you jump the thermostat and obviously don't let it run too long but it'll tell you if it's going to work. It's going to be blowing HOT air out the back and it's going to be venting CO into your house, but again hypothetically, I'd do it for 30 seconds before I gambled on a unit working.
