EE22 is a lock out code that keeps you from continuing to try to start the heater. This code usually pops up as the result of a problem with the fuel supply (i.e. no fuel, fuel sys obstruction, clogged filter, water frozen in line, faulty igniter), but could be more serious. To clear the code the easy way, unplug heater for at least 30 minutes. While you are waiting, check your fuel tank to see if you have fuel. Then check filter to make sure the element is not clogged and that there is no air or water (or ice) in the fuel line. If you find a problem with any of these things, correct it before trying to start heater again.

Call manufacturer or Installer - Direct Vent Furnaces are not a DIY service. Carbon Monoxide is deadly and can easily be emitted if there is something wrong with the heater. Get professional help before anything further is done, as it needs a full inspection for your safety.
How long is the exhaust pipe on the inside of the house? Is it covered with a cloth sock? The EE 6 is probably from air in the fuel line. I am a little confused by the term "our downstairs heater". Do you have a lifter for the L30?
It may be the room temp sensor. Have you relocated it? It is on the back of the heater? It needs to be away from the heater where it will not sense the heat high heat coming out of the heater, and also the cold wall behind it. Usually a bit up, and then to the side will work. Play with it and the temp setting til you find one that is comfortable.
Could it have to do with the temperature sensor? If it is still coiled up on the back of your heater, it may be turning the heater off. You need to uncoil the sensor wire, and place the sensor somewhere away from the heater. One sight said atleast 8" off the ground. (I have a Laser 73 and mine is about two feet to the right and about 8 foot up on my wall as I have a lot.) You can attach it to a board if you have to, or any other item. Just put it as far away from the heat of the heater as you can so it will only be sensing the room air temp. If the line needs to be longer you can cut in stereo wire (I read this online too). Then play with the heat settings to see at what temp it is most comfortable for you. Hope this solves the problem.
My business is Laser Heating Service in the North Pole/Fairbanks area of Alaska. EE12 is the error code for overheating. Most likely you have a Laser 30 giving you this error code. The most common reason for the EE12 error code is that the Toyo is not getting enough air circulation across the heat exchanger and causing it to overheat. Look at the back of your Toyo where the black frame around the circulating fan and flue pipe is. You will see a screen that slides in a slot at the back of the Toyo. Slide the screen out and clean it. If you have a smoker or the Toyo is in a kitchen area where it collects nicotine or grease then you may need to clean it with hot water, detergent, or 409 Cleaner to get the sticky residue off that the dust fuzz collects on and clog your screen. EE12 can be caused by a couple other issues, but they are more rare. Try this first and let me know if it works! toyotechnician
My business is Laser Heating Service in the North Pole/Fairbanks areas of Alaska. An EE2 error code is usually fuel related. What does your Toyo do before the EE2 code shows up? If you let me know the sequence of events, I can trouble shoot the problem for you. toyotech
EE-22 means that the unit has tried three times to ignite. after this it goes into a "lockout" condition. remove the power and the computer will reset itself. it will then try to re-ignite. check for a fuel blockage, dirty filter etc. if there's water in your kerosene it will not fire! kerosene floats on top of water. bleed your system until you get kero and no water. use a gas additive to remove water. dry-gas will work. just empty the bottle's contents into your tank. on your computer type in toyostove error codes. this will take you to toyo's site and explains the error codes.
