Clean burn won't light

[dannyo]

The burner swings out. If I lift up the ignitor i can attach the lead to the electrode.
This is where Im sure of myself. Is one side hot and the other ground?
If not please educate me.

If you prefer you can just swing the burner out, I just find it easier on the bench. What you want to do is take the blue wire from the ignitor and the black wire from the combustion air motor #8 bottom row and tie those together to 1 wire on your extension cord. Then take the neutral wires from both of those items #1+#3 bottom and tie it to the other wire of your extension cord then plug into 110 volt outlet.

This will power up the ignitor and the combustion air motor will throw the spark out in front of nozzle.

There is a spark on the electrodes and the motor runs.

Is the spark shooting out in front of the nozzle ?

[dannyo]

Its more over the top of the nozzle.

[ShopSpecialties]

Is that with the combustion air motor running ?

Are the electrodes in good shape and adjusted properly ?

[dannyo]

Motor is running
I adjusted the electrodes per Cleanburn manual
The arc does not seem to be at the tips

[ShopSpecialties]

Ok there is your problem. With the burner swung open and both the ignitor and combustion air motor running you can easily see what the spark is doing.

Are the electrodes in good shape ?
Is the combustion air blower full of dirt and not blowing much air ?
Have you messed with combustion air setting ? When bench testing you can adjust your combustion air and watch your spark change.

I have ordered an electrode it should be here today. The nozzle is clean.
When I get the electrode I will adjust the air and see what happens.
I will get back to you Thanks

[dannyo]

Replaced the electrode and set, good spark.
The furnace is trying to fire, a lot of smoke. Won't light.
Oil pressure is 3.5, calls for 1.5 to 2.
I'm not aware of an adjustment for this.
Could there be trash or restriction causing an increase in pressure?
How is the pressure regulated?

[ShopSpecialties]

Does your burner have 2 black knobs sticking up above the burner ? Right below they are labeled "oil" on the left and "air on the right ? The mount to the preheat block and those are your regulators.

[dannyo]

It only has one for air.

[ShopSpecialties]

Ok, so you have metered pump that delivers a set amount of fuel and is non-adjustable. Pressure readings do not mean much with this setup since it goes by volume.

What elevation are you at ?

[dannyo]

575’

[ShopSpecialties]

That is good, I just wanted to make sure you were not at high elevation. Set air at 12-14 PSI and start with combustion air 1/4 of the way open. After all the raw oil is burned off and flame is good and established you can dial in your combustion air setting.
