air pressure should be no more than 3.5 psi. could be your pressure is too high and is blowing out the flame.

SOURCE: All Pro 200t Will not ignite

John- the ignitor does not stay on for the duration of the running time. It only stays on for the first 5 seconds. This is long enough for the flame to ignite and perpetuate itself, assuming the fuel delivery system is up-to-par. The photocell monitors the flame color and if the flame becomes off-color then the photocell tells the control board to shut the unit down. Naturally, too rich or too lean affects flame color.

Now, I'm confused by your description "the heater cycles 3 times". Tell me more.

I'm glad to see that you checked the pump pressure. Have you used soapy water to check for air leaks all the way to the nozzle? A leak in the airline, fuel line, or a crack in the nozzle adapter will cause no fuel delivery, or reduced fuel delivery as well as reduced atomization of the fuel - all of which can cause a lack of combustion. A restricted fuel filter will cause starvation.

Eliminate all possibilities of a fuel delivery problem before you start blaming electronics because there is not much way to test the board or the photocell successfully without DESA's diagnostic tool. Unfortunately, replacement of the componants is cheaper than the tool.

SOURCE: Kerosene forced-air heater won't start

Rick---A couple of things to check. With the unit off and unplugged, remove the spark plug-(Note-there may be a little setscrew which you have to remove first)----Put the plug wire back on the plug and ground it against the side of the heator and start it just briefly to see if the plug fires----If it does, then again with the unit shut off, remove the nozzle which has a set screw holding it in. The nozzle has 2 rubber lines running to it and leave them on and then start the unit (Note, be aware that in this test and the plug test that when its plugged in, the fan runs, so keep the plug wire and the rubber lines away from the fan) With the nozzle removed, watch very closely to see if a mist comes out of the nozzle after you plug it in. If no mist comes out, then you probably have either an air or fuel problem.---With the spark plug test, if there is no spark at the plug, the easiest way is to install a new plug and if there is still no spark, then the ignitor is probably bad----------On the nozzle test, try taking off the 2 lines on the nozzle, one line goes to the fuel tank and the other line is the air line (take note which line goes where) first blow thru each connection on the nozzle to see if its plugged and if its not then blow thru the hose going to the tank and you should hear a bubbling noise in the tank--if not then, its plugged or the hose is split----------The other line is the air line and if you can't get anything on it, the filter may be very dirty----behind the filter, there should be a port for checking the air pressure when the unit is running----The unit I have runs on 3 psi pressure, BUT yours may run on a different setting--That psi setting may be stamped on the unit behind the filter---Hope this helps

SOURCE: pro 110, runs 10 min., blows white smoke ,shuts off

the first thing you need to do is go back to useing K1 kerosene, diesel fuel not only burns dirty but also has a tendency to gel up in cold weather which could be makeing it hard for the heater to draw the proper amount of fuel. To reset the pressure you will need a gage, it should run at about 6-7 psi. you can order a pressure gage from mr. heater online, they are by far the cheapest I have found as they are the actual manufacturer or call 1-800-251-0001

Here is a link to your owner's manual... http://12.153.20.74/manuals/123919-01A.PDF. Look on page 8 and 10. It could be several things. It could only be a dirty fuel filter or the pump pressure may just need adjustment. If you need a part you can contact Master Parts at 800-466-1446 or you can find them on-line at www.masterparts.net. I hope this helps!

toddbrewer1,

This is a classic All Pro, Reddy Heat, Master Heater, etc problem. They are all made by DESA International and similar in operation. They control fuel pressure by bleed air. As the air filter plugs up the pressure changes and that is why your unit runs with the top off. You allow more air to flow. You need to replace the air filter and set the pump pressure. I have a tip at

http://www.fixya.com/support/r4124129-yearly_maintenance_reddy_heaters

which is written for Reddy Heaters but as I said before they are all the same. It tells you how to complete the repair and where to get the parts.

Thanks for using FixYa and for the great rating.

Running very rich. how to adjust fuel and air screw


First of all are you running kerosene or diesel ? If you are using diesel, it does not burn as clean as kerosene which causes that burning rich smell. If you are going to use diesel, just use #1 diesel only but still may have a little rich smell. Don't use die red off road diesel. If you are using kerosene and want to check your air pressure on your pump, you will need a 10 lb. test gauge with a 1/8" NPT male pipe thread on the end of the gauge.There are 2 plugs on the back plate. Do not remove the upper plug with the hole in it. This is the adjustment screw for pressure. Clockwise increases pressure, counter clockwise decreases pressure. With the heater unplugged,remove the lower plug. Screw the test gauge in and start the heater. Check the pressure. Most are set between 5 1/2 and 6 lb. of pressure. Check your owners manual to see what your setting should be. If your pressure does not change, you have a worn pump and it would have to be repaired. Once you have the correct setting, unplug the heater, remove the gauge and install the plug back. If you feel that you are not qualified to perform this procedure, send it in to a local repair center.

Kerosene heater produces a lot of soot.


you are deffinitely not getting enough air to fuel mix, check your lines for breaks. If they are ok you will probably need to pressure check it.
