Proper oil pressure

zepfan Member Posts: 375
What is the proper oil pressure of a waste oil burner? I have a lot of experience with regular oil burners where I am used to seeing 100-150psi, but this is the first waste oil heater that I have worked on. The unit in question is an Energy Logic
Model MH 15602
Serial AS461212
Thanks to all

    You should get a manual and check, or call their tech support. Pressure is can even be very high 200-300psi.

    Completely different animal. Start with 2 PSI oil and 10-12 PSI air, -3 Nozzle

    They do not self adjust, pay attention to what goes in the tank.

    Steve 200-300psi of what?

    I was talking about pump pressure. The few I worked on had high pump pressure. Although looking at the manual I see it's low between 3 and 15 psi.

    Nasty burners. Think of them as a semi controlled tire fire.

    Think the consumer has been mislead with most of them.

    ISTR the old Winkler low-pressure burners could burn waste oil.

    Here is your owners manual.


    Energy Logic has authorized dealers that can provide service. I live in an area where the authorized dealer is over 3 hours away round trip. So I get this call to look at one, Took me several hours, over 3 days, to read up on the product then take everything apart, clean the gook out of the preheater, nozzle, and fuel lines, then get it all back together and start it up.

    Now I'm the area expert and not sure I like to be the go to guy for waste oil heaters. I have over 40 years experience on oil heat and I'm pretty good at it, Still took some time to understand concept and sequence of operation for this beast. If you are not good with mechanical things, you might want to call the number in the manual for help.

    Just remember, You are getting free fuel for your heater, Spend some money on qualified service and you will have dependable operation.
