Waste Oil Heater Forum - Your definitive source for burning waste oil for heat.

I vacuumed out the ashes, is that what you mean?

With the box fan blowing across the top it does what you described now and the Cleanburn fan blows a decent amout of air. I noticed that the back metal cover is not sealing that well and I think that might be contributing to this because it isn't allowing all of the air to move across the heat exchanger and away from the unit itself.

I'm glad to know it is functioning as it should now (if I'm understanding what you wrote correctly), even if it is a little rigged for now until I can get the air flow issue and leaks resolved.

Thank you once more for all of your help, I could not have done this without you.

The wires are as you stated and the black wire is now in the spot labeled #3 on my picture.

The unit still runs for 20 minutes or so, hits 200F on the thermostat, shuts the burner off, shuts the fan off after an additional 60 seconds, then the thermostat pegs and it gets really hot. After 10 minutes it cools down enough to turn on the fan, then after 60 seconds or so it turns on the burner but then it cools down so much it turns off the fan while still running the burner, which then heats the unit up and turns the fan back on after 2 or so minutes. Then it tuns for 15 minutes or so and then the whole cycle repeats itself.

I woul think the fan should run the whole time it gets hot? Is that cycle normal?

While you are at it lets double check the wiring if you have not already.

Orange wire will go wiring junction on side of heater to fan.

Red wire will go to yellow power cord, once inside the burner it goes to the little preheat block temp switch, once block is warmed to 120* +/- the other wire on the switch sends power to the primary control.

No need to apologize, I'm the newb here . I'm glad I verified though.

So you are telling me to move the black wire from spot 1 to spot 2 then, correct?

Once again I apologize for thinking we are both thinking the same.

I visualize the fan limit switch in the upright position when I describe it. On your heater it is laying on its right side. So when I say ' bottom right ' I mean that while looking at it in the upright position with the dial on top.

With all the different brands I work on they have it mounted differently so to make it easy in my head I remember it in the upright position.

Does that make sense ?

I think the unit is getting hot enough to where it shuts down to protect itself ... is this possible? It had turned itself off when I had went out and when I switched the black wire location it was already off from being so hot so nothing happened. I'll have to check it tomorrow when it has cooled down I guess?

It is 8" long.

Here is a pic, I've noticed that it turns on the fan when I turn the unit on (power wise) and then it turns off, the unit heats up and it then it starts. I noticed it will sometimes get very hot and turn off and then run the fan for 60 seconds or so and then turns that off. Then it sits not running for 10 minutes, cools down and turns on again. It gets very hot when this happens and I would think the fan would run while the unit was off to cool it down, but it doesn't? Is this normal?

Thank you for that, you've been a huge help to me.

I wonder if the auto/manual part isn't working properly? I've seen the thermostat portion rotate, so I believe that part of it is working.

I cannot remember off the top of head what length the CB 2800 is, it will be 5" or 8". Measure yours to make sure which one is correct.

Honeywell L4064B2228  5"
               
               L4064B2236   8"

Just punch those numbers into Google and you will find places that will sell it for cheaper shipped to you.

I consider it to be a problem.

I called 2 locals asking them to hook up my system and asking for an estimate. They wanted to charge me windshield time for an estimate, which I think is asinine. Had they came out and given me a reasonable estimate, I would have told them to go ahead, but I feel they wanted to gouge me because of the protectionist region that Clean Burn provides them and the mentality that can result from that. I even told them they could make it a time when they were servicing a current customer in my area but presumably because of the lack of competition, they had no interest in doing that.

This does not build trust with me. That is when I set about to get it installed myself. I still would have rather paid someone.

Where can you get parts for my cb2800?
