Okay...so last year I bought a Hot Water Dragon 8 GPM Unit. My plans changed and I tried to sell it on here without any takers. Okay. So...I own the thing. Stick it in my warehouse knowing full well I was going to be building another rig at some point. That point is now. Full blown Powerwashing/Roof cleaning rig. New rig is 80% complete and is turning out beautifully (NPR 15' Box truck build). Fired up the unit, cold section was tested a few days ago and it worked great with a Big Guy 4 Bar Surface cleaner. Sweet. So...today was the day to fire the burner up and make sure the hot section was working before I put it to work on a job next week. Now keep in mind, I am no stranger to burner systems...I bullt the only biodiesel fired structural drying mobile furnace in the United States called a BioDry system. It has a burner that is 5x the size of the one on the Dragon, complete with a Honeywell control panel system. So, this isn't my first go around. Put a diesel fuel line on and put a line on the return with a valve so I could bleed it. Tank is right next to the machine so no return to the tank is apparently necessary according to the manual. Time to test this puppy out and get me some hot water!
This...is where things go bad.
First, Fuel...spraying out. From behind the control panel?!?
W.T.F.???
Pulled the control panel off. Turned out that the fuel pressure gauge connector was really loose and kind of flopping around.
Tightened it. Ahhh...easy fix, but should have been tightened at the factory. Put the panel back on and fired it up.
Fuel again..but now it was spraying out. A LOT more. Sh!t.
Took the panel back off and discovered the reason why. The F-F threaded barrel which adapts the male barbed fitting to the male gauge input was split. This is why it was loose and why tightening it made no difference and why fuel was still spurting out. Don't have another barrel fittting in that size. Stick a bolt in the line, clamp it off. Don't really need the gauge to test things. Clean up all the spilled fuel as best as I can.
Okay...ready for hot water! Flipped the switch...the other end of the fuel pressure gauge line at the pump blows apart. Literally shreds itself. Fuel spraying EVERYWHERE. REALLY??? Quickly flip the power switch off.
Take the connector off, I'll just block the thing off...rummage...crap...of COURSE I don't have a screw of that size with that thread to block if off.
Sigh. Snip the line short to a good section, and clamp the heck out of other end.
Fire it up, fire up the engine, all the burner lights come on...sweet...hot water, here she comes!
Any day.
Heat?
hello?
Nothing.
No heat. Could be air in the line? Yeah, probably air in the line.
Bleed valve line blows off the pump, spraying me and the right side of my truck with diesel.
Neighbors start to move their children indoors to escape the extraordinarily colorful language now emanating from inside the white truck up the street.
Shut the burner off. Again.
Fix the problem. Fire it back up.
Burner lights come on...no heat, nothing.
Does it require some pressure restriction... or will it make hot water open flow? Don't know because the manual is nowhere to be found and isn't on the website.
Then...the engine died. Just shut off.
And won't restart. Plenty of gas in the tank. Choke, throttle, nothing.
So now I am covered in diesel fuel, the formerly clean and sparkling truck is plastered n slippery smelly D2, my hand is bleeding from the insanely sharp edge on the control panel.
The engine won't start. I smell like a refinery and I've given up and am heading for a hot shower.
Help.
