Commercial Waste Oil Heaters / Re: clean burn 2500

Thank you for sending the video. It appears your on-board air compressor is shutting down. Lets start with cheap/easy things to check first. Clean air filter ? Double check all your wiring connections to make sure we do not have a loose connection somewhere. Especially in the on-board air wiring box where there are a few wire nuts and capacitor. Is the compressor still getting power when it shuts down ?

Waste Motor Oil / Re: clean burn 525 oil pressure fluctuates
« Last post by ShopSpecialties on November 13, 2019, 09:54:48 pm »
Im quite sure all is well with plumbing as it worked perfectly for 5 winters.   The temp is at 140,  but ive raised it up and no changes.   i always kill the power to unit if its not being used, as i was told this keeps the block from plugging up.  Doesnt  quite add up how pressure at the gun varies so much.   seem like the longer the unit is off, the higher the pressure on start up.  once it settles to  about 2psi all is well.   I guess a rebuild and re clean all passages again is a good starting point
P.S.   one thing i did notice today.  units been running pretty much non stop, oil pressure holding steady at 2.  If i quickly raise air pressure to 20 psi   the oil pressure rises to 2.5 ,   if i lower the air to 10psi the oil drops a little too.  is there a connection between the two?

I just noticed your PS. Oil pressure should not change when adjusting the air. Bad o-ring on the nozzle ? Has the nozzle ever been changed ? Also make sure the nozzle t-stat is functioning properly. I have had them fail closed then the nozzle heating element stays on constantly baking the nozzle o-ring.

i have 2 tank, one outside, and one buried ,   switching them really makes no difference to the problem.  the buried one has slightly more vacuum on the lenz gauge.

I just did one a month ago with the same exact issue and after burner rebuild it is all good.

Another thing to possibly think about is have there been any changes to your oil storage ? Is the oil cold, room temp, etc ? With the oil in block being being 140* it will flow easy and the longer the heater is not running the colder the oil is in the tank. Hot oil flows easy and flame grows while cold oil flows slower and flame shortens. The more the heater runs the more consistent the oil temp is and the oil pressure stays steady. The heater only burns a hair over 1 gallon per hour so it will take a significant amount of run time to empty the block.

When I do a burner rebuild I totally tear it down and scrub out each passage until spotless. Regulator and solenoid bodies cleaned spotless. Nozzle holder scrubbed out. On some preheat blocks I have had to clean up passages with a drill bit. The oil solenoid has some small passages on both the body and block that need to be checked closely. Every burner rebuild gets a service kit installed.

Sounds like things are good from pump to tank so that leaves the burner. What is your preheat block temp set at ?

First thing  is a Thank You for trying to help.    Yes its a 1750 with a J pump.   I've cleaned the block, every plug removed and soaked and scrubbed until spotless.  all three filter screens cleaned.    installed a pressure gauge  on j pump pressure line and its always 25 lbs,  vacuum is close to zero at lenz filter.    there are 2  oil tanks plumbed together  and same exact reading  on either tank.   the unit ran last night no problem and pressure stayed just under 2psi. being it was 20 degreesout  it never stayed off for long.  when it sits and cools down for a few hours, it will start and light instantly, but pressure rises to about 5psi.  this makes the  flame sputter and  usually caused a lock out. with consistant  pressure and vacuum at J pump i cant imagine what can make pressure so erratic.  new oil regulator also. What is involved in a burner rebuild?
