Question about Heating & Cooling

1 Answer

I have a Rinnai High Efficiency 30 space heater that cuts out. When I turn it on, it starts up as usual, runs for about one minute and then the flame cuts out. Then it won't light at all (you can hear the auto ignition ticking and then it gives up). Only if left for a while it will then light as before and cut-out after a minute. The fan runs OK and I have vaccumed out all dust.

Hi there,

Sounds like the heat ignition sensor is stuffed and needs replacing. Before replacing it try blowing out the burners and pilot light. Sometimes it is just the burners that have carboned up and need cleaning. If it does the same thing after this then it will be the sensor.

Hope this helps

Regards
Bryan

I get a high pitched whistle from my r94 rinnai. what causes this?


It's generally caused by either low gas pressure to the heater. Or what is called a "Cold Burner". If it is a :Cold Burner" ... Once the whistling starts, turn the heater off, wait 3 to 5 minutes and turn it back on and turn the flames to a middle setting. If there is no whistling, set your flame height/temperature where ever you like. The low gas pressure issue would need to checked by a qualified technician. At the same time, have them to check the air mixture control valve on the burner.

Hope this helps solve your problem. Please let me know.

Toyo stove laser 73 throws a EE 2 code and back fan will not come on.


EE 2 can be caused by a couple of things but is usually a fuel issue or a flame rod problem. The circulation fan will not come on until the burner has warmed up. The combustion blower should start almost as soon as you turn the heater on. Turn the heater on and listen for the combustion blower. If it doesn\'t start, do you get an error code? If the blower started wait for the fuel pump to come on. It will start when the burner lights come on. If the fuel pump makes a loud ticking or thumping sound, it isn\'t getting any fuel. Check the fuel filter and the strainer in the fuel sump. Make sure the valve is turned off at the barrel before removing the fuel strainer. If the fuel pump is working normally, does the heater light up. If it doesn\'t, check the igniter. You can check that first if you want and have a clamp on ammeter. Place it around one of the igniter leads and you should read 2 to 4 amps when you turn the heater on. If the heater does light but then cuts off after about a minute, clean the flame rod. Unplug the heater before removing the flame rod because it may kill the circuit board if the heater is plugged in and the flame rod touches ground. Let me know what you find.

My heater runs for about 10 minutes then the flame cuts out and can't be turned on again till it cools down for half an hour...


Hi.

Replace the flame sensor, if that does not fix the problem, check the thermostats, if it cuts off in ten minutes and then restarts when cooling down, then it is either flame sensor or thermostats.

Do rinnai heaters run efficiently if turned up and down often?


Maintaining the lowest acceptable setting and leaving it at that temperature is the most economical way to run the unit. If the space is going to be unoccupied for an extended time (several hours), lower temperatures are okay. This minimizes the need to burst the heat to warm the space quicker. As I understand your unit, it minimizes electrical & gas consumption by basing the need on the temperature difference of actual space temperature and setpoint. The larger the gap, the more power and gas is consumed.
In summary, when the space is occupied, maintain a consistent temperature setting. When the space is unoccupied, maintain a lower setpoint.

Hope this helps. Good Luck. :-)

I have a rinnai heater and it stopped working all


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.

Rinnai heater flashes code 12


Bailey,

Next time you try your stove watch the flame. If the flame goes away and then the error code comes on, you have something wrong with the over temp circuit, gas or gas valve, If the code comes on and then the flame goes away you have a flame sensor problem.

Good luck,

Laser 73


My Laser 73 does the same thing at least once, and sometimes twice, a year. The EE6 code is what the onboard computer gives when it THINKS the flame has gone out. Now, it COULD be that all that is wrong is you are out of fuel, OR you have water in the fuel. But....the more likely scenerio, (and what has always gone wrong with mine) is a common problem in the flame pot:
There is a stainless steel baffle near the bottom of the flame pot. (about 2 inches off the bottem). This baffle is used to "form the flame", cause it to curl up around the inside edges of the pot, where the air intake holes are, to create a clean-burning, high-efficiency blue flame. Over time, this baffle becomes horribly warped and distorted from the intense heat. (an engineering design screwup, IMO) (but you'll never get them to admit it) This warping of the baffle, in turn, causes the flame itself to become uneven, and to also begin burning poorly, with soot deposits. One of the first hints this is happening is lots of YELLOW flame, instead of the usual blue. When this happens, the flame SENSOR becomes sooted and dirty, and no longer is able to sense the flame. It tells the computer to shut down, because it thinks there is no flame, hence the "EE6" code. This sensor is simply a stainless steel rod poking into the flame pot. It's on the front of the pot, two screw fastening, and has a single wire attached to it, which runs to the computer. It is used to detect IONS (minute current) running from the flame front to the pot itself. (ground) And....(as if all this is not enough), the gaskets around the middle section of the flame pot, and at the top, usually develop cracks and leaks.
Cleaning the sensor (with steel wool) usually isn't enough to fix this problem. You will likely have to replace both of the fire-pot gaskets, the flame pot baffle, and also the burner "mat". (a round, flat, fiberglass mat glued to the bottem of the flame pot. Vacuum out all the dirt and soot. The baffle "unscrews" with about a quarter-twist CCW. (lift upwards on it, while turning CCW) Use fire-proof sealer on the new gaskets. Plan on all day taking it apart, and back together again. (a time consuming job...no fun) Good luck!
