If...the air pump pressure is right, the ignitor glows, the fuel is hitting the ignitor, then the unit will have combustion......unless.....

  1. there is an air leak on the pressure line
  2. there is a vacuum leak on the fuel line
  3. there is a leak at the nozzle adapter
  4. there is a restriction either in the nozzle or the fuel filter
  5. the nozzle is worn and is spraying fuel rather than fogging fuel

To Justaskjoe, I have put in all new filters, new pump vanes and cleaned everything real good. I put new hoses on incase there was a leak. Cleaned photo eye and even tried a new one. I have fuel spray coming out the front, plenty of spark on the plug, new fuel. I and several others are at a lost here.

    I had basically the same problem, and after cleaning the fuel pump and installing the proper
    tank hose, I discovered the vanes in the pump where installed backwards that kept it from running properly. After inserting the vanes properly it rns like a champ.

    I found out that it was the cup in the nozzle. Took it out, didn't look bad, but turned it around and ran fine. Bought a new nozzle to have on hand if it quits again down the road.

My kerosene torpedo heater turns on but then it dies after five seconds


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.

I HAVE A 115,000 btu Keroscene heater. It just stopped running.


Take the top cover off of the unit. Plug it in and look inside the burner can to see if the ignitor is glowing. If not you probably need an ignitor. You can remove it to check the heating element to see if it is intact, but be very careful, it is more fragile than glass. If it is intact, you may have a control board issue. The ignitor should glow before the fan starts. Be careful to stay away from the fan blades while doing this. If the ignitor glows, and the motor starts, you should then be able to see fuel spraying out of the spray nozzle. You may need a flash light. If the fuel does not spray out of the nozzle in the correct amount, the unit will shut down. There is a photo cell that detects ignition. If the fuel pattern does not look even, you could have low air pressure out of the pump, a dirty fuel nozzle, or a plugged fuel screen inside of the tank. The air pressure comes from a pump on the back side of the blower motor. Insure that the filter are clean on the pump; there are three of them, and the plastic end cap needs to come off to access them. If they are dirty, they need to be replaced. The air pressure off of this pump is very critical to proper fuel delivery. The rated output pressure of the pump is on the heater data plate. You will need a low pressure air gage to check this pressure. Another source of low air pressure is the plastic end cover over the filters. They tend to crack with age. Spray soapy water on the end cap while the blower is running to look for leaks.

Wont fire after following start instructions


OK-- Let's go thru your trouble shooting steps, and what you found:

1.) Fuel: Sufficient, and right type?

2.) Has the unit fired and run before?-- What is different in sounds, or settings now?

3.) How does this unit ignite the fuel?-- With Spark, or with Glowing ignitor?
If Spark-- can you hear it sparking?

If Glowing ignitor, -- can you see the glowing? (in a darkened room..)

4.) Can you see that Kerosene is spraying at the nozzle?-- is the pattern correct?

5.) Have you check fuel and air pressure settings-- according to the manual?

After observing these details-- let us know what other clues you are observing now.

I'll be here to take you to the next step, if you like--- Just add your new comments in the 'respond' box-- they will send them to me for further follow-up.

Problem: Will not spray fuel through nozze. Lines are not clogged. Have cheecked spark plug. It is firing. Special note: It is Series 35,000 Reddy Heater.


You can try adjusting the pump pressures, but it does sound more like the pump went out on you. Have you checked to see that the shaft to the pump is turning? I am not sure how that mates up with the motor be it a set screw, or coupling, but would check it over the pumps are generally not an issue.

Dayton 70,000 btu kerosene heater only runs consistently with 3/4 of a tank of fuel or more. Once it is below 3/4 it keeps shutting off. I have cleaned filters, tried to set pressure but pressure won't go...


If you can only get 4 psi from the pump then you have a problem with the rotor. This could be from the vanes not coming out properly of if you have replaced or serviced the rotor you may not have the clearance set properly between the pump ring and the top of the rotor.
Make sure to inspect the pump cover for any small cracks..

If you pump pressure in not enough the unit will not be able to pull fuel from the tank and you will see the burner cone slowly start to go from the orange color to a dark color and the unit will shut down.

Not getting fuel after air and fuel filter maintenance.


If the maintenance procedure included anything that required you to dis-assemble the air pump then you must simply re-set the pump pressure in order for fuel to be pumped into the combustion chamber. . It's an easy procedure. Instructions for setting the pump pressure

Sears forced air kero heater wont start, spitting fuel out front


sounds like the ignitor is bad, mine would try to light and do the same thing. I noticed one night that it was arcing out the entire length of the wires to the plug. If you have a good spark then i would suggest a CAD flame sensor, very cheap.

100,000 btu therm controled heater


What did you set the air pump pressure at? This is critical on heaters with Hot Surface Technology. Setting the pump pressure is always the FIRST place to start troubleshooting on these heaters.

Here are some things that can prevent ignition even though there is fuel & glow:
  1. wrong air pump pressure
  2. the nozzle is restricted & distorted not allowing fuel to contact the glowing ignitor
  3. the nozzle is worn. It should produce a cone of fog, not a spray.
  4. there is water in the tank below the fuel.
