Waste Motor Oil / Re: Oil pressure regulator

The pickup screen goes in the tank to stop the big chunks and the check valve screws onto it to keep the oil from draining back after the burner shuts off.

I do not see a check valve or a pick-up screen.   is the pick-up screen separate from that filter?  would the check valve be in the line somewhere? - if so, then i dont see one.    just copper tubing into that filter, then into the motor, then into the spin filter, then over to the furnace.

Lets start off by getting a working oil gauge to help diagnose what exactly is going on. Then you can watch the gauge to see if it is a slow fluctuate or a sucking air bouncing up/down.

The Lenz filter is good and is there a 3/4" check valve and pickup screen ?

Obviously a burner rebuild would be high on that list also.

Start getting all these little things right then see if we can find a happy medium with the settings so it runs all the time with just small occasional touch ups.

Awesome, thank you for the information shopspecialties! 

Ok so are you saying, that it is normal that i continually 'manually' adjust the oil pressure by turning the external knob?  I get it that the oil pressure will fluctuate.  but i feel like it fluctuates to the point that causes it to trip off.  is that normal?  or do i just need to be standing by all the time to correct it?  I guess what im asking is, if this was running ok, should it run all by itself for days without needing tweaked? 

Ok, I will work on the plumbing, and eliminate that spin filter, and redo the lines, and adjust the electrodes.   

does the other filter look right?   is there something else that you would recommend?

When the power is on the preheat block is always maintaining temp as determined by the adjustable block thermostat. The oil solenoid is BEFORE the preheat block so with this burner you will always have some fluctuation in oil pressure.

Your suction side plumbing is a mess with way to many connections where you could suck air. The spin-on filter is not necessary. Plumb it the way I showed you to ensure you are not sucking air and make cleaning the filters easy.

Yes, electrodes need to be adjusted properly.

Ok.  I understand initially that the pressure will need adjusted as the oil heats up inside the block.  but then after that, mine still constantly needs adjusted.  or it just shuts off.   i use it when I am going to be away for a day or more.  I get it running fine well before I am leaving, like 12-24hrs before hand it works the whole time before i leave.  but then when i come back home i find it tripped off and the house is cold - thankfully no broken pipe situations yet haha.   when i come back home, i turn it back on, and usually it fires up fine - maybe a slight adjust of oil pressure initially, but it works fine.  So i am trying to find out why it keeps tripping off, so it can become something a little more reliable.   

You think it may be a viscosity issue?  My oil is stored inside, in the furnace room.  if its a viscosity issue, then i cant do anything about that.   

what about this filter, pictured?  I was told that as long as the gauge didnt get into the red then i didnt need to do anything.  but the gauge has never moved in two winters, so i wonder if that is even working.  should this filter be replaced?  cleaned?  removed? (I also have a large spin on filter in the line - are two filters necessary?)

Next question, last week I took the nozzle off to clean it, and i must have bumped the two points (whatever exactly they are called, im not sure, the two points where the spark arks across) because it wouldnt fire after that.  So i pushed them a little closer, and then they worked.    Is there a way to measure or know if they are set right?  or as long as its sparking and igniting the flame,  is that good enough? 

thanks for your help shopspecialties, and anybody else!

Oil gauges are cheap and easy to change.

Like I said in my previous post oil pressure will fluctuate on these old style burners due to the location of the oil solenoid. With cold oil you will have to turn up the pressure so it flows enough through the small holes in the oil solenoid. Then after that oil warms up it flows easy through the oil solenoid so your flame grows and you adjust your oil pressure down.

The more consistent temp you can keep your oil storage at the less the pressure will fluctuate. Also big changes in oil viscosity will have an effect on oil pressure.

No i did not do that yet.  I have all the information saved on my phone, though, for when i am ready.  I have not used it much this year at all, and didnt have the money in the start of the season.   well, still dont lol.   I actually thought about using my tax money and buying something totally different, like a heating oil boiler, for when i am away and not burning coal, which is why i did not invest the money in the waste oil burner, but now i am probably not making that investment right now.   

Ok, well the pressure regulator I am talking about, is external, right as the oil comes into the burner, and there is a knob to adjust it.  I was told by previous owner, that it should be set so the smoke coming out the chimney is clear (because the gauge doesnt work) so that is where i have kept it set.  but then there are times that it seems starving, or suddenly pouring oil, and the smoke is very black, and i need to adjust it.  sometimes it trips off, and i wonder if its cause of improper oil pressure, etc.

So last Fall when I recommended you do a burner rebuild and install a service kit did you do that ?

On these old style burners the oil solenoid is before the preheat block so as the oil gets warmer/cooler oil pressure will fluctuate. Also make sure you are not sucking any air and have a constant steady supply of oil to the burner.

Waste Motor Oil / Oil pressure regulator
« Last post by ajparry89 on February 18, 2019, 07:26:46 am »
Hey everybody, I have an old style Clean Burn waste oil heater, bolted onto an old old coal boiler - something i inherited with the purchase of a property.   anyways, I think i could use a new oil pressure regulator - for one thing, my gauge is not working at all, and plus, i constantly have to adjust the pressure, i think its cutting in and out.  so my question is, where should i shop for one?  im guessing i dont have to get it straight from clean burn, i feel like that might be an expensive route?  any aftermarket ones available?  sites to shop?  im relatively new to burning waste oil, this is only my second year, and I haven't purchased anything for it yet! haha.   

thanks for the help!
