Have a Dayton model 2E510/a/b/c torpedo heater
Jowens8648,
All these types of heaters were made by the same manufacturer, Desa International. I would go to
http://www.reddyparts.com . They would have any parts you would need and probably a repair manual.

E-1 code were are the filters ? how long are the
In order to find the fuel and air filters you must first remove the top section of the heater tube, this is done by removing the six to eight 5/16" hex headed screws. Now once the top section has been removed you will have access to the fuel lines, they vary in length as to where they go so a simple measurement takes care of that situation. Filters are as follows, the air filter is at the back of the heater assembly, it is usually a foam filter and it is in the air pump ( black plastic pump). Then there are actually two different fuel filters, first one is a screen filter just behind the fuel nozzle. You have to remove the fuel nozzle and there is the screen filter, while you have the nozzle out you can clean it by using a blow gun and compressor to blow air thru the nozzle and make sure there is no blockages. The second is located under the side cover, so trace your fuel line down to where it comes thru the heater tube and again remove the 5/16" hex head screws to expose the fuel line. Now some have the filter right there in plain sight and some depending upon the year have it in a grommet in the fuel tank top.Again remove it and I clean it the same way with compressed air blowing backwards thru it as well. Make sure that you have tight fits on all fuel and air lines, make sure the nozzle is clean ,the screen filter is clean, and put the nozzle assembly back together. be careful not to damage the nozzle.While you have the heater down make sure to clean the flame sensor, for this I use windex and a soft terry cloth rag. Put the heater tube back together and you are ready to test.
My 3v starts off great blows a few seconds and
No if it were a thermocouple it would not light period. You may get a pilot light but nothing else. What you are describing is a simple fix, your flame sensor is not detecting fire. To cure this you have to remove the top section of the heater tube and look down below the fan and off to the side you will find the flame sensor usually in a tube of sorts. These get dirty, collect carbon deposits or insects love to nest here so clean it with windex and a terry cloth rag. Now aim it into the area of the flames with an unobstructed view put it back together and try it out. This should solve your your heating problem. Good Luck!!
Heater works fine but you
This doesn't have an easy fix to it. Sounds like the fan motor is very weak, probably the brushes in the motor are worn out and I doubt you can replace just the brushes. Probably have to change out the fan motor. Good news is these are common heaters and parts should be available. Try Grainger on line or even Dayton on line and see if there is replacement parts for the fan.

Dayton heaters at one time were manufactured by DESA or a predecessor and labeled DAYTON for Grainger. I have been unable to find any specific reference material to "Dayton 3EV51".There were 2 types of motors used. I suspect your heater has a starter relay. The solid state relay was used to allow the energizing of the start winding which would allow the motor to achieve approx 80% of rated speed, then the relay would de-energize the start winding to prevent overheating. The relay is not attached to the motor, except for the wiring.This is what the starter relay looks like. If yours has one check to see if it is energizing the starter windings at start-up. If not it is probably defective. The part is still available at www.reddyparts.com, I think, but today's replacement part looks slightly different.If your motor does not have the relay, then the motor has an internal start-up system which is not serviceable, but the motor is probably still available. Most of the time the motor's part number is printed on the label.
2E511B torpedo heater would shut down within
There are electronic components within heater that may be confusing the ground fault. I would try using a non ground fault plug while troubleshooting unit. These motors tend to fill with debris that could be shorting windings, remove top cover to expose motor and inspect. The motor should turn freely and you should hear slight clicking of pump vanes that supply air to nozzle. If motor is slightly stiff and no vane clicking, most likely too dirty to operate correctly. Heater shuts down when electric eye does not see flame, eye could be dirty or bad. Look for flame immediately after start, if no flame fault could be too little /much fuel, no fuel reaching nozzle due to pick-up tube, old fuel, faulty plug, faulty spark coil, or dirty vane pump that supplies air to nozzle. Heater will not operate correctly with out top cover at least resting in place. Good place for parts is masterheater.com Good luck
I have a 2E511C heater
You probably already know this . The 2E511C was manufactured by DESA for Grainger, so you must follow these
Reddy Heater troubleshooting tips.It sounds like the heater is not getting fuel or the fuel is not hitting the spark and you must troubleshoot and find out why.
Contact me for a Dayton to DESA parts cross reference chart.
Need service manual for dayton 3ev51 heater?
Below the Fixya web page there is an icon that is 'find manuals' Click there but when asked by that search engine do not enter the M/N. The manual site will ask you for the model #; but if you enter the model number with the manufacturer initially, It may get confused and say "No data for Dayton 3EV51. Start out slow and then fine tune the search later on.
