Not really, the limit switch is like an emergency cutoff. If it reaches the limit, it shuts down.

When the rotor has been replaced, you will need to reset the clearance at the top of the rotor and the pump body for the correct operation, details can be found in your manual. Too wide a gap and you will have low pressure, to small a gap and there is the risk of damaging or scoring the new parts. Once the heater is running, adjust the air pressure so that the flame is staying just inside the combustion chamber or just around the edge of the end plate. It should be red hot and burning without any smell or un-burnt fuel. Damage will be caused to the combustion chamber if the flames come out the end like a jet engine, as well as being dangerous. It's not really necessary to use an actual pressure gauge, use the performance as your guide. Pressure gauges are a useful diagnostic tool if repairing heaters is your business, because you can immediately tell if the fault is caused by air pressure or other problems.

The heater will not ignite, but this problem could have several causes! Do you mean that the motor is running, fuel at the nozzle but although there is a spark, the fuel does not ignite? This could be caused by low pump pressure, loss of spark could be the HT cables, or the ignition transformer. Is the electrode in good order?? An intermittent spark could be faulty electrodes or ignition transformer. Is the fuel clean and the correct type?? Is the fuel contaminated with water, is the fuel filter clean?? Dirty fuel could cause this problem.

I'm sorry to tell you, but your question is in the wrong category. This one is for heaters. However, is it possible you can find out about your truck by calling the Department of motor vehicles? It had to be registered sometime, and they will know. :) Don't you have the vehicle registration paper? Or bill of sale? It should say the year right on it.

REAL FACT is: If all individual components of the heater are at 100% but the air pump pressure is not on it's mark, then the heater WILL NOT continue to run!
Air Pump Pressure is directly related to fuel delivery. Read that statement again! It is the most important line of text on this website.
If the pump pressure is incorrect, then, the fuel delivery will be incorrect. As a result, the heater will not run to specs.
Instructions for setting the air pump pressure:
Air pump pressure is the pulse of the heater. Pump pressures range from 3 psi to 6 psi depending on heater BTU size (see chart below). A loss of ONLY 1 psi translates to a 30% to 17% loss of FUEL FLOW (starvation). You must know the specified required pressure and set the pressure accordingly.
Heaters with Hot Surface Ignitor technology are extremely critical to pump pressure. If the pressure is off by 1/2 psi, the heater may run for 5 seconds, then shut down because of IGNITION FAILURE. The only way to correct this problem is to set the pump pressure to DESA's recommended pressure specification.
  1. The FIRST STEP in diagnosing any heater problem should be checking the output of the air pump. Determine the air pressure required for the heater model that is being tuned. The air pump, in turn, is responsible for fuel delivery.
  2. If you do not know the required pressure look for a decal on the side (usually) of your heater. This decal will state the model number, serial number, fuel capacity, pump pressure, etc.
  3. If your plastic end cover looks like this......
m29609t.jpgM29609 has 2 threaded holes. The hole on the left has a square plug inserted. Remove the plug. Screw in the nipple end of the gauge into the threaded hole. Check for air leaks with soapy water.
or
If your plastic end cover looks like this......
m16545t.jpgM16545 has 2 threaded holes. The shorter projection with a hole on the left has a square plug inserted. Remove the plug. Screw in the nipple end of the gauge into the threaded hole. Check for air leaks with soapy water.
4. The other hole (longer projection) has a screw with a hole which adjusts a ball and spring relief valve assembly. Carefully adjust the screw until the gauge is reading the pressure level that is specified on the heater's label. If operating properly, the pump should produce more pressure than is required to operate the heater. The relief valve allows the excess air to escape before being sent to the nozzle.
5. Replace plug. Test for leak.
6. If you are unable to reach the desired pressure spray soapy water around the seal of the end cover- at the same time check the plastic cover for a crack. A cracked end cover will not allow the heater to perform properly and will not allow for an accurate reading. The pump must be set at the specified pressure in order to have adequate fuel delivery an adequate fuel atomization. Replace if needed.
7. If you set the pressure to specs and the heater does not perform properly or the cone does not glow a soft red, then check for other fuel delivery problems such as a clogged fuel filter, cracked rubber hose, clogged or worn nozzle, or a cracked nozzle adapter. Soapy water lightly sprayed in these areas will quickly identify the problem most of the time. Any air leak will create problems.

what is your air pressure, very important. Air pressure should be between 4 to 6 pounds.

sounds like you have dirt in your fuel tank, as the heater runas it picks up the dirt in the filter plugging it up. When the heater shuts off, the dirt falls out of the filter. You start the heater back up and it does it all over again. Empty your tank and change the fuel filter. Should be fine then.

You will have to clean it all out every where the fuel goes tank , lines igntion etc if you had not run it you could have just changed fuel , now its best you clean it all .

SHOULD NOT BE SPRAYING FUEL OUT THE END. TURN THE PRESSURE DOWN BY TURNING THE FLAT HEAD ADJUSTMENT SCREW COUNTER CLOCKWISE IN SMALL INCRIMENTS.

Optical eye which verify's ignition is probably dirty. Find it and clean it.

I would call Beals & Bobs @ 712-225-6173 or you can go to www.bealsmotor.com and email them and they will answer you questions and email an owners manual if you want. They have a service manual for these heaters at http://www.bealsmotor.com/heater.html and then click on the Desa manual that you need. The kerosene manual if for heaters with a spark plug and the Hot surface manual is for heaters with an ignitor.
