Rinnai 2001 Gas Heater - turn off

Hi,

My gas heater turns off after about ten minutes. I am assuming it is a safety feature when the thermostat gets to hot. The cuase I don't know. I paid a repairer $99.00 12 months ago to vacuum the heater, but it still keeps happening. Any ideas?

Cheers, David

    I have a Rinnai 2001 Gas heater that the pilot light ignites the main flame, then after several minutes when it heats up the fan comes on but the main flame goes out and the fan continues to run until cool, then the fan turns off and you can start the pilot light and continue the cycle. I have disconnected the fan and the main flame will continue to run.
    Any hints would be greatly appreciated.

    I have a Rinnai Rinnai REH301EB Space Heater, when the heater has been on for several minutes it turns it self off, I am assuming that the thermostat is kicking in, when it does this though the pilot light goes out to, anyone have any solutions

    I have exactly the same problem except the space heater is Rinnai model REH300FTC. I vacuumed it but to no use. Can you tell me did you fixed your problem? What was wrong? Or shall I rather look for a new heater?

If, like me you have a Rinnai **** heater, with a PCB Assembly, then thats what the problem is. Look at around $500+ installation. These PCB's are not repairable. For $500, I am going to trash this heater and get something from a company that does not want to screw me after I have trusted them to live up to their "REPUTATION". Do not support companies that do not support their customers!

When the repair guy cleaned water heater did he run white vinger through the coil inside the heater. Does the control pad show any errors

    what model is it? Have you taken out the filter to make sure there is no restriction of water flow.If you have a manual look on page 43 it will tell you the flush procedure. If you don't i can send you the page.

Hi my vulcan gas hot water service isn't getting hot enough anymore? please help me?


check first if you have good water flow to and from heater. lift pressure release valve on inlet and allow few sec to flow, same with outlet hot water safety valve.

remove front cover from the heater, you should see your gas connection and thermostat knob.

check if gas is burning evenly and on whole surface, check for leaks on the heater and on the lines to and from the heater.

if you did not find any faults, no leaks, safety valves work correctly, check thermostats settings,

wind it down to minimal, then turn it to about 1/4 value (you did not specify model but this should do, widening arrow or numerical values ar self explanatory), lift hot water safety valve for few seconds, then open any hot water tap (faucet if you are an american...) and check if gas ignites and burns.

set thermostat to about 2/3 value and again, lift hot water safety valve for few seconds, then open any hot water tap. check if gas ignites and if water is sufficiently hot, if too hot - wind it down to say 1/2 way, if too cold, wind it till resistant and then back off a bit, DO NOT EVER LEAVE VALVE OR THERMOSTAT ON MAX!.

if none of these help - you need either, change the thermostat or heater itself.

if works - you solved the problem, close the tap, close the cover and use the system as you normally do.

i am always recommending use of insulation on the hot water system, it saves heaps of money over the life of the system.

hope this will help you - do not forget to vote... :-)

The difference between thermal fuse and thermostat


Thermal fuse is a heat-sensitive safety feature that shuts down system when overheating is detected.
In electrical wiring, the thermal fuse reacts to high temperature caused by too many amps on the electric circuit. When temperature exceeds the fuse amp rating, then the fuse trips and cuts power to electric circuit.
Example of thermal fuse is a household circuit breaker.
Gas water heaters have a different type of thermal fuse located in the combustion chamber or on the combustion chamber door, and also inside a copper probe inside water tank. Water heater thermal fuses will trip when water temperature exceeds fuse rating, or when heat inside the combustion chamber exceeds temperature rating of fuse. This action will cut off gas supply to water heater.
So a thermal fuse is a safety feature.

Thermostat is not a safety feature.
Thermostat is a measuring tool.
Thermostats measure temperature.
Example of thermostat is outdoor thermometer, or cooking thermometer, or Heat-AC control located on wall inside house.
Thermostats can give a simple temperature reading, or they can cause a separate control to turn on-off depending on application.
For example thermostat on Heat-AC will read room temperature, and when temperature exceeds setting, this triggers a switch that turns Heat-AC on-off.

Many appliances have both thermal safety fuse and thermostat.
Take for example a gas water heater. A copper tube extends into the water tank. Inside the copper tube are 2 things: A thermostat probe to measure water temperature, and a thermal fuse called an ECO for energy cut off. The ECO is a thermal fuse, and is a safety feature.
http://waterheatertimer.org/images/Gas-valve-ECO2-358.jpg
The thermostat reads temperature of water, and turns water heater on-off to keep water hot. A person can adjust water temperature by adjusting the thermostat dial on front of water heater.
However if the thermostat fails, or some other problem occurs, and water inside the tank gets hotter than 180 degrees, then the ECO or thermal fuse will trip. When the thermal fuse trips, this turns off gas to the water heater so water cannot get any hotter. The safety device prevents water heater explosion. The water heater must be repaired since this particular thermal fuse cannot be re-used afterwards, and must be replaced.

Installed new wall heater and thermostat and pilot is on but heater will not come on?


What about thermostat wire? What ya got 2 wires right? Touch them together she supposed to ignite the flames then after a few minutes the fan kicks in on fan models. You got the knob on the gas valve turned to the "ON" position?

Our coleman fireplace insert starts to warm and then shorts out


Not sure if you have an electric fireplace or a gas fireplace. But, from the way you worded the description of your problem, I'm going to assume that it's electric. I'm also assuming that all the other features of the fireplace work, but the heater doesn' t. If that is the case, below is what the Owners Manual recommends doing.

5. Flame effect operates, but heater does not blow warm air

The TEMPERATURE button is a thermostat control for the heater. Each preset temperature setting has a different thermostat setting as shown to the right:

The heater will NOT activate if the room temperature is above the thermostat setting. If the ambient room temperature is 78° F the user will need to select Setting 3 in order for the heater to be activated. It is normal in warmer climates and in rooms with higher ambient temperatures for the heater to not activate on the lower settings due to the thermostat control. 5a. Try increasing the temperature setting. See drawing:

temp-control-fig.jpg 6. If unit heater does not function, but Power and Heater switches are in the "ON" position and thermostat is set on "HI" 6a. Turn all switches to the "OFF" position and unplug the unit from the wall outlet for 5 minutes. After 5 minutes plug the unit back into the wall outlet, and operate as normal.

The pilot light is ON, but we are not getting hot water...help!


Hi,
There are a few issues that can cause this....
First... Is this a new installation??? If the hot and cold piping is reversed then you will not get much hot water...
Does the burner come on at all??? If you turn the thermostat up higher does the burner come on???
If the dip tube on the cold water inlet disintergrates or falls off... you will not get hot water but the tank will be warm-hot....
If the burner will not come on at all then the thermostat has gone bad and the t-sta/gas valve will need to be replaced...
To replace the t-stat and gas valve you will need to drain most of the water from the heater and turn out the old valve and then replace it with a new one...
Sometimes the onetime limit safety cutoff on the gas valve will burn out.. usually because of a gas valve/t-stat failure....

This should give you some ideas as to where to start looking...

Comment back to me if you have more questions...

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.

Turns on but no heat


From what I saw when I googled you furnace it has a hot surface igniter. It only gets hot when it's time to light the furnace. You should be able to see it glowing red when the furnace is trying to light. The furnace has a safety feature which shuts the gas valve when it doesn't detect a flame to prevent gas build up in the furnace. There are other safety features also. If the draft inducer motor isn't running the gas valve won't open. Overheat switches some of which have to be reset manually. Adjust the thermostat until it calls for heat then observe what is or isn't happening in the furnace. It will go thru a purge cycle first. The draft inducer motor will run to do this. After the purge the hot surface igniter should get hot a glow, then the gas valve will open and the burner will light. Let me know what you find.

Heat runs ten minutes than heat shuts off continues to run


I'm thinking the thermostat has failed, it get's too hot and the emergency over temp sensor kills the flame before a fire is started.
