Scott- so when your cleaning with hot water with the wand the burner runs clear and the water heats up OK but when you let off on the wand does the burner stay on?(I couldn't get the sound on my I-pad) also is that a 12v or 120volt burner??

The way that smoke looked without hearing the sound it seems like the burner stayed on but there was no fuel getting to it. It's hard to tell with the sun glare and no sound. The only time I had problems like that was from a 12volt burner because the battery wouldn't stay charged enough..

Interesting to see what the Experts like Russ J. Says.. Burners people tell me aren't that complicated but the biggest problems I had over the years where with my burners including blowing out the pipes from a propane sonic boom.
 
John the burner turns off when the gum if closed and burns clean when the gun is open.

Jerry from Sirroco just called me and to walk me through the cause and solution he thinks I have........Thanks Jerry I appreciate the help.

Looks like I need to adjust the air band and/or the reed valve on the flow switch and install a fuel pressure gauge to make sure it where it's supposed to be
 
That's unburned fuel evaporating away. Leave it be. It might take some time to clear up, but it will.
 
Yeah it looks like the left over disel burning or smoldering from when you soak the bottom from a mis-fire. Its not from the air adjustment on the fan but i do agree those things need to be adjusted in a open type trailer from one season to the next, To get the best burn. When that happens to me I just turn my heat up a bit more than usual so the burner gets hotter and burn the excess fuel away. Keep an eye on it you dont want a fire. Ive never had one but It would suck having to spray water into your burner to extinguish it. I do agree a fuel pressure gauge is a good idea but not related to your problem. Key phrase is its burning clean when trigger is pulled.
 
This Russ agrees with the other Russ, use it and just watch it to make sure you dont have a fire.

I had one keep burning once, it didnt hurt anything but it freaked me out a little.

What happens is when your ignitor goes out and is not creating a spark to ignite the fuel the pump is sending, then it just builds up in the insulation, so when you fire it again it starts burning it off, be careful cause the water can get got and also if it is on fire it will be heating the coil when the gun is off as well.

I agree with agreeing with Russ.

I had one shoot flames all over the place one night at a hospital under the canopy of the emergency entrance. That was a sight to see
 
Burner issues: White smoke after the main-flame goes off

I explained to Scott..
Since the smoke didn't clear after the first hour of use, and the "main-flame" was burning clear..
the air-bands must be too far open, or the fuel-pressure is set a little too high.. (probably over 120psi,)
both of which can "elongate the fire-ball"..
that pushes the fuel-spray up against the bottom of the coil,
allowing the fuel to re-coagulate, back into bigger droplets,
causing fuel to remain, after the main-flame goes out..
thus, the white smoke.

Being meticulous ALWAYS gives you a clearer understanding of how things work, and how they fail.
There is more downtime associated with heater problems than other systems,
because the perfect fire.. is a "Balancing Act" ..NOT luck.

Get a pressure-gauge on your fuel pumps, know the set-pressure,
and be familiar with the functional range of the air-adjustment on YOUR system.
..or one evening, when all the techs have gone home.. you'll wish you were more confident in your knowlege.

Scott,
since that heater is 10 years old..
I should have mentioned.. the burner nozzle is probably worn..
Replace that if the air adjustment does't reduce the white smoke.

..and use soot remover if there is EVER any soot build-up on your coil.
 
The most expensive mistake do-it-your-selfers make..
not getting the heater perfect, allowing a smoldering fire to burn when there's no water flowing,
and blasting the coil.

The nastiest mistake..
allowing the coil to soot-up to "choked".. unable to burn at all..
and having to remove the coil to clean it..
a horrible mess, and ..totally UNnecessary.

Ditto to what Russ said! More you run it, more it will clear up.
