Hello everyone, I have just placed my order for a EKO-25. I have been reading about them on this site for a few months now. I plan on having it hooked up with my oil boiler and add storage next spring when I save up some more cash. The question I have is when this thing is all hooked up is it pretty much set to run from the factory. Or do I need to adjust anything like the air or fan to start. Thanks in advance for the information.
