We have a breckwell model P23fsl we just cleaned the exaust pipes the day before yesturday, it will start up, fans are running fine, it flames high orange flames, it acts like theres wind blowing the flames comming from the back firewall, after a few minutes it shuts off and flashes #2 or a #3 cant really tell HELP its our only source of heat and we are in Maine

Running an engine hot like that it's going to be toast. You will need another engine or replace the car.

sounds like its shuting off on high limit, make sure exaust pipe is clean and outside termination as well, poor air flow

Might be a good idea to check your timing first and then if the timing is ok try removing your exaust pipe and running it for a few minutes without the exaust system installed. I have encountered a couple of bikes where the exaust system has carboned up and will not allow the engine to breathe especially at hiogher rpms. A day in the gunk tank for the exaust pipe did the trick and the bike ran like new. (Gunk will remove all the paint too)

first clean the burners and check injectors are clean yellow flame is lack of air to burners , check pressure is not too high IE right pressure to burn .

Check for a codeon the control board. Also while the system is trying to start up, do you see the ignighter glowing, If not prolem could be a bad igniter. Problem could also be an obstruction in the exaust pipe, if this is the first time of the season it is turned on, and it is not firing, check to see if a bird got into the exaust pipe that vents to the outside. You need to provide more information, such as a code to troubleshoot this problem.

Check the flame sensor is clean and the connections . check out pressure switch and the hoses . check air filter is clean .

The most likely and more common problem you are describing is affiliated with the flame sensor. The good news is that you can generally correct this problem with a scotchbrite pad and/or some light emory cloth. I'm going to give you a link to a youtube video that shows you how it's done.

I hope you found this helpful to you. Good Luck! :-)

Flame sensor would be my first diagnosis. Take it out and clean it with some emery cloth or some light grit sand paper and put it back in should be fine just needs to be cleaned.

rinnai, toyostove and monitor heaters are basically all the same. first you have to make sure your fuel valve is open at the tank. next you have to reset the tank lockout on the sump. then set your set point higher than your room temperature. now press on. the unit will go through a 300 second purge cycle. the pot heater should turn on when the purge cycle starts. after the purge cycle the fuel pump turns on and pumps fuel into the pot. when it vaporizes the igniter lights it. when a flame is detected the flame rod says ok to keep running so the fuel pump shifts into high speed. when plenum temperature reaches a preset level the fan turns on.
