I have a model R115 hot ignition kerosene heater. Originally the heater would ignite( good yellow flame) after 4 or 5 seconds it would shut down. According to the troubleshooting guide I replaced the ignition control assembly(circuit board) & photo cell, did'nt help at all. Since then I have replaced ignitor,set pump pressure @ 5.3, new fuel filter,new air & fuel lines, cleaned air filter,cleaned nozzle, checked for leaks at nozzle adaptor & pump housing. Nozzle sprays a good even pattern. Now heater will run indefinetly with top cover removed( would't run at all before except for the 4 or 5 seconds). I can now place the cover starting at the exhaust end & gently lower it to within about 2 inches at the pump end before the unit shuts down. I have watched the flame very close as I lower the cover & noticed it turns more blue than yellow. I have called & talked to two factory technicians neither one had any concrete suggestions for a remedy. I'm at witts end. Can you help before I junk this heater that looks like new? The heaters with sparkplugs were much more simplier & reliable. Oh yes new fresh kerosene too! Thanks, Larry

Does the blower motor start when you plug it in/turn it on? It may take around 5 seconds if your heater has a HSI(hot surface igniter). If it does you need to check the igniter and the fuel flow. Either way, remove the top of the heater. You will be able to see the fan, igniter, and fuel nozzle. Turn the fan by hand to see if it turns freely. If it does, watch out for the fan and turn the heater on. Look for the igniter to start sparking (spark plug type) or glowing (HSI type). Next, use a flashlight to look for fuel spraying from the nozzle. If fuel isn't spraying, try cleaning the fuel nozzle and check the fuel filter. Watch out for the HSI, if you have one, they are very brittle and easily broken. If you still don't have fuel flow after cleaning the nozzle and the fuel filter, you may have an air pressure problem. Let me know and I will tell you how to check it. Don't forget to rate the answer if it works.
The EE22 code means the heater has failed to ignite for 3 tries in a row. To reset this code you must disconnect the power from the unit for 30 mins. You should figure out why it isn't lighting first though because you will build up kerosene in the burner if you keep trying to start it. If you hear a ticking sound when the pump starts it means there is no fuel getting to the pump. There could be some fuel gelled up in the sump under the fuel pump. You can check your igniter by feeling the igniter cover but be careful it will be very hot if the igniter is working after a short time. Hope this helps. You can contact me at email@example.com
If it actually ignites and burns but shuts off either the flame sensor is bad (or dirty) or the control is bad. I would verify the flame sensor is clean and had good electrical connections to the controller for starters.
I have same heater and problem-1) Check fuel inlet screens at bottom of hose in tank 2) Check air filters at fan module opposite end of the fan blade 3)Check for spark in ignition chamber 4) Check for fuel flow in ignition chamber (look at pressure gauge at opposite end from air exit) You'll have to remove the top cover to do these checks. The side covers will hang on each side ok. I hope these checks help you out.Good luck.
A heater with this problem is probably the hardest to determine the cause. There is no carb orn thermostat to adj. If it uses a spark plug ignitor I would check the plug gap and make sure it is at an angle to the nozzle. If it has Hot Surface Ignition this will not be the problem. I would then check the fuel filter in the dip tube in the tank and the pump pressure. I should be about 4.5 psi. I would also remove the nozzle and replace it or at least blow it out backwards withlcompressed air to clean it. If all these items fail to correct the problem I would replace the flame sensor. Let me know what you find out or if you have any questions.
Typical kero heater uses either a spark ignition or a hot surface. The hot surface igniter is very fragile. A small bump may break the elements. Flame is detected by a photocell, signal is sent to the lockout relay board. Change the igniter costs about 50 bucks.
most parts for kero heaters are interchangable. go to desatech dot com for parts. check for a reset button for your heater. if no reset, does the fan run? your unit can use one of two ignition parts. a spark generator with a spark plug or a hot surface igniter. the unit uses a cad cell flame detector. you might need to replace this.
