hi,i'm new to this forum.i never been to one like this,it's usually the car forums.anyway,i've never installed a furnace before especially a commercial waste oil burner.i service them rarely because all my customers have natural gas one's or sometimes lp and mostly all residential.this unit has been modified coz i see it doesn't have the swing out burner assembly.also i believe this is not the right controller either.the electrical gang box has had it's wiring all taken apart.i downloaded the manual but in it's schematics that i'm not used to reading this style shows round male and female connectors-there aren't any and there is no hinge to swing this assembly out.i'm stumped on how to wire it from the gang box.hopefully from the pics you can see what wires are in the gang and where they should go.i started from line hot to the black on the fan control and then started to lose it.it's funny because i troubleshoot electronics and electrical but just can't get this one.i've done many ifc replacements,full boiler hook ups with 3 zones,etc.i'm no expert but my success rate is very high for the past 18 years-otherwise i don't get paid.i started cleaning drains and then it has escalated over the years to the electronics.i'm still learning of course.just the stack install alone took too long ,i'm pressed for time and thought that clean burn's manual would bail me out with their diagrams.there must have been a revision since 1986.this unit worked before disassembly by the previous owner who then sold it to the new owner who said it worked.i don't know i wasn't there.any help would help to steer me in the right direction if you can't help me here please .thanks.i will post this here first before adding the 6 pics i have because my prior to my test post failed after 3 attempts to send all this and images too..wtf?..
