It works!
Got everything installed a bit at a time over the last two weeks. This morning I put a gallon of diesel in and fired it up! Priming the fuel system took longer than I expected. Smoked like a chimney for a few minutes but cleared up nicely on the second run. I had to double clamp the exhaust connections, but they seem good now.
I need to swap out the 110v power cord for one with a switch. I don't want the 12v power supply to run all the time, just when I want heat. But for now I'll just unplug it. Right now it is 66 degrees in my office, so no reason to turn in on but tomorrow morning I'll fire it up to see how fast it warms things.
Funny, my garage now has an exhaust pipe.
