Soot?

[hubcap]

I think the machine I bought might need the soot cleaned out of the burner. Checking the temp out the other day all I could get out of her was about 180. Is it a dificult job to pull the coil out and clean her off? Do I have to replace the insulation or can I use the old?

What make you think it needs to be cleaned? Some machines will only produce 180-200 degrees.....Don't rely on the thermostat knob

What you need is called a "descale" basically acid wash your coil. http://www.epowerwash.com/wp/archives/2748 - there is some information on it.

I think there is a debate in the industry whether descale is even necessary. You can definitely damage your coil if you do it wrong, especially on older coils.

LOL, the knob on the thing goes up to 300...I dont expect to get 300 but I thought i could do better than just barely 180. I've looked all over the thing and the only model number I can find is a tag on the side that says...

Wayne EHASR, Firing range GPH 0.75-3.00 120 volts-60hz-5.50 amps. Does that mean anything to anybody?

My Ford Ranger said it would go 120 but there was a limiter on it at 95.

Gene is right, the knobs lie.

Does the coil look sooty down the stack? A black coloring is much different from fuzzy, flaky soot. How old is the machine? When was the last tune up? Do you know what the fuel pressure is? The nice thing about the 120 volt burner is it can support larger fuel nozzles, increasing the output temperature.

I don't know when the last tune up was, I just got the machine about 3 weeks ago(still learning all this stuff). I changed the oil in the motor and the pump shortly after I got it. There is place for a pressure gauge so I'll see if I can find one and install. I don't have a stack, just a hole on the top at one end of the burner.


not a very good pic...not fuzzy but it looks a little flaky.

don't look too bad

Thanks guys, I really appreciate all the help I'm getting on this site.

I don't think it's a soot problem...maybe a dirty fuel nozzle...maybe wrong fuel pressure.

I have some Diesel Kleen i used to run in my old diesel truck, I wonder if that would clean out the nozzle. Any one ever use any fuel additive like Sea Foam?

Are you using the proper nozzle on the gun?

Do you have the steam knob on the plus or minus side?

 

[hubcap]

Yes, got the right nozzles on the gun, and the steam knob is turned to the minus side.
