Toyostove laser 56 H burner coating or burn mat

I'm cleaning out my laser 56 type H heater, I have cleaned out the blower and I was going to replace the burn ring. This heater has a burner coating according to the manuel, should I put in a burner mat like the newer heaters? Would this improve the flame performance?

Hello again. I inherited a Laser 55 from a family member a few weeks ago. It had a few issues getting started but I was able to fix them and get the stove running thanks to redniten on this website. ...


As long as the gasket isn't broken you can reuse it but be careful becaust they are very easily broken.
I use a thin bladed screwdriver to remove the carbon and old glue, then vacuum up the mess. I sometimes use my sandblaster just for good measure.
If I'm not mistaken, there is a notch on the burner mat. Put the notch under the fuel inlet. I put a bead of the white adhesive all the way around the mat. I also put a drop in the middle. Press the mat down good and flat.
Hope this helps.

Laser 56 howls or sounds like a horn when transitioning from high burn to medium burn and has a high yellow flame. How can I fix this? thanks


The high yellow flame is probably due to a loose burner mat or a warped burner ring or both. As for the howling I'm not sure about that but would be related to the airflow, maybe something to due with the blower.

Low heat output. Older Laser 72. Does something


It's likely that the burner mat has came loose or it has a lot of carbon buildup in the burner. Look at the flame when the heater is on. It should be mostly blue with slight yellow tips. You might need to clean the fuel nozzle also. You can remove the fuel pipe where it connects to the burner and use a piece of wire or an allen wrench that will fit in the nozzle that goes into the burner to remove any carbon that may have built up. You can also clean the burner but don't destroy the mat in the bottom. You can find the owner's manual at toyostove.com and it will give you some more things to clean.

I have a toyo laser 56 stove. It is starting to make a moaning noise. what shoud i do?


Pilot,

You need to have a new mat put in the bottom of the burner. When this mat lifts, sometimes the flame will cause a moaning noise with a large yellow flame. A new mat and maybe a burner ring will fix ya.

Laser 56 howls like a banshee, but only when burning on medium (yellow light) Just serviced by authorised tech. Replaced burner mat, heat chamber gasket, vent gasket, and fuel filter. Did not have this...


He might of gotten cleaner into the berings on the blower motor which will make it squeel like a dirty bearing sound.
If it's a low howling noise check that the squirrel cages are tight and not slipping. Also check for restrictions in the air intake.

Toyo 55, igniter gets hardened build-up


Gartyl,

Your Laser 55 burner mat has erroded away. The fuel is pooling someplace in the burner rather than spreading smoothly over the bottom. The stuff on the igniter may be hardened carbon from a poor flame. Bottom line is some burner work. A new mat, ring and cleaning the burner air holes is in order. Don't be surprised if the heat chamber is cracked beyond repair when you get it off. NOW for the bad news. The Laser 55 and 72 are older heaters. You will find just about all the electrical parts are going to be hard to find. They are no longer being made. Your 55 will be able to use the newer 56 blower, mat and burner ring. You will also be able to use the heat element off a 56 as well. If there is a problem with the fuel pump causing your poor flame you will be out of luck.

Good luck,

Toyostove laser 73error codes


EE 6 can be some kind of obstruction in the fuel line causing the fuel to not reach the heater. It could be the high limit switch being activated. For that they say clean the fan, and fan cover. Your tank could be too high. The fuel sump valve could be malfunctioning. I think you would need to replace the pump for that. (It probably is not that as your heater does run for a while.) Finally it could be a flame sensor malfunction. Did you notice if there is a lot of carbon built up in your heat pot? It could be building up on the flame rod, causing the heater to not be able to sense a flame. Is your burner ring (the metal thing that sets inside the heat pot) warped? This will cause your heater to go out from time to time as the fame burns erratic and too hot, building up more carbon. Replacing that burner ring if it is warped could solve all your problems. You might wantt o replace the burner mat while you are at it.

Toyostove 72 won't go on high.


Replacing the burner ring (center piece?) will do wonders. When it's warped the stove won't work properly.

Toyostove Laser 56 EE 2 error


Tim,

I have been working on Toyo's for 14 years now. During this time I have never seen a flame rod that was bad except ones that people have broken themselves. The rod is just a piece of heavy wire that is insulated against the pot. It is almost impossible to mess it up. Now, that being said, you can have a problem with the flame rod being dirty or sooted. Since your stove is so new I would look at the fuel system. If it is clean I would go after the burner mat. There have been mats lately on new stoves that have caused them to soot up. When this happens the flame rod gets covered with soot and gives the EE2 message. A new stove that has a burner mat problem would be covered by the warranty. Bad fuel that causes a problem will not be covered. The other thing that is not covered is a stove that has had an iced up the exhaust pipe. A good dealer should be able to help you get the stove going and explain the warranty.

Toyostove Laser 56 (F type) making loud humming noise


the toyostove is basically a glorified monitor heater.  its components are a combustion blower, an air circulator fan, a flame pot, a flat wick or burner mat, a solenoid pump, an ignition element, double  walled intake, exhaust pipe.   the combustion blower is a glorified vacuum cleaner motor. it sucks in cool air and channels it to the combustion chamber along the sides (round cylinder) kero enters on the burner mat where it ignites. the solenoid pump keeps adding kero until the flame detector spots or heats up. air flow to the pot is regulated by a damper in the combustion air blower line. if the "O" ring in the damper is missing or hardened it will not regulate the air flow which is necessary for combustion.  replace this "O" ring should take care of your problem.
