Question about Reddy Heater-30-55,000 BTU Variable

1 Answer

I have a 35,000 btu Reddy heater that won't fire at the spark plug but is getting a signal from the magneto. Is the magneto bad or does the spark plug have to be in the mist of kerosene to spark?

I haven't used the unit in probably around 2 years but I emptied the tank and added new kerosene. The kerosene is squirting.

    I know that the unit is getting spark from the magneto but maybe it is not strong enough? I felt it spark when I touched the spark plug cable. I also checked the gap and tried another spark plug.

  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......

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.

Is there a frost line on your LP tank, if so you may need to replace the tank with a larger tank or refill your tank. This can happen if the tank your using is too low or too small (use 100 lb tank or greater). If there is no frost line it may be an issue with the thermocouple. The manufacturer offers a service manual and owner's manuals on there site. This should assist you... www.desatech.com Thank you

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.

Reddy Heater Doesn't fully ignite


First thing I would do is clean all of your air and fuel filters and check your lines for breaks. A lot of times they will do that if your not getting enough air to fuel mix. If it continues after that it's the CAD/ flame sensor which you can get from MR. Heater for 3 bucks they are all basically the same and I know reddy heater wants 18 for the same thing.
