200,000 BTU Oil Fired Dayton: Shuts off

Hi there ! Our unit pretty much stopped coming most of the time and stopped after a few minutes when it did come on. I read your solution on checking for fan blade clearance with the couling. We blew out the rear section with compressed air, added small washers under the couling lip to raise it 1/16", put the couling back on. It fired right up and ran great for about 5 minutes and shut down. When we ran it with and without the couling on it seems to have a lot of good fan pressure. Is there a manual and or more trouble shooting tips for this size unit? Do you know what my next thing to check is? Thanks in advance, Mike Quante

    In my post I mentioned I was looking for a manual etc... so I would better understand the solution info. I really don't understand the terms you are using. I do not know where the cut off / cut on settings are. Which way to turn them? Etc... Etc... In addition, I posted this under E52. I do not know the exact E Series this unit is but the model # is 3VG79B. It is a 200,000 BTU unit. It has "Hsi" Smart start technology / Hot surface Ignition system. Without a manual I need plain talk like: Take that black knob thingy located in the left rear of the unit just under the red knob and turn it 1/4" clockwise until... Thats the kind of help I need. By the way, we added some more small stacked washers under the couling raising it to approx 3/16" - 1/4" up from the base and it has now been running for 2 hours straight if that info helps. Do you know where I can get a manual as well? Thanks, Big Mike 542 "The unknowing One" !! LOL

    I really need you to spend a little more time on your responses to me so I know what you are saying. You posted a link just after the word manual so I assumed thats where I could get a PDF manual to print. I go to the site for 15 to 20 minutes and not only could I not find any manuals I can't even find my type of heater in there. Tell me what this link is for ?? I found just about every kind of heater you can imagine but nothing even close to mine??? Tell me about this thermister in the flame properly (what is the proper setting of it)? If you are going to help me trouble shoot this without me having a manual and no knowledge of how it works I need you to tell me what you are saying in more detail and why. Thanks, Big Mike

    ok where is my brain all thermostats have a cut on cut off setting your cut on may be right but your cut off may be too low so its cycling off too low there for too early

  • robert samples Jan 15, 2008

If the fan was working, but the fan is not working now after replacing the whole kit, then something was installed incorrectly during the installation, possibly the rotor gap or rotor thickness is not correct or vane/vanes installed 90 degrees off.

The sensor for the thermostat is probably going bad or has bad connections. It is (or thinks it is) heating up fast and therefore shuts of the heater.
