Are the thermocouples used in these small vent free ( with oxygen sensors ) fairly standardized ?

Thanks

Not familiar with those units to say. Can you post a pic of it.

They are not allowed here, so I've never seen one in person. Thermocouples all use the same principle and are generally very very similar. They need a surface area significantly smaller then the grounding plate, (burner or heat exchanger) be fairly clean, and have no cracks in the insulating ceramic. (and it can't be coated with grime either)

You can get Universal versions, and can bend, and cut the length to whatever needed. The only problem will be if it uses a standard mounting bracket.

Cheers!

Your thinking of a flame sensor. Not a thermocouple.

Here is a photo of the heater . Can not show the pilot assembly & thermocouple with out taking it apart again .

Hope to not have to do that , as long as it is working .

I think this may be the thermocouple it uses ?

I was just thinking about buying one as a spare , it they are reasonable .

I have different brands of blue flame heaters in the computer room and back bath room .

Thanks ,

This part " proves " the pilot is lit . One end in the pilot flame and the other end screws into the gas valve .

That would be a thermocouple. As super says, you can get universal ones.

I don't think I have ever seen one which can be "cut" though

You don't bend a thermocouple as he posted. Nor do you "cut" them to length as Super said. So he was probably talking about a flame sensor, and not a thermocouple.

The heater in the pic, may actually use a thermopile, and not a thermocouple. The OP would have to clarify which it actually uses.

Do not know for sure , but I think it is a thermocouple . I know nothing about thermopiles ?

I may have bent the mounting bracket ?

I also bent the pilot assembly , to get the flame more directly on the thermocouple .

I think some one else mentioned cutting one ?

if you bent the pilot assy to get it into the flame or directly on the thermocouple.....maybe all it needed was a pilot cleaning ....as mentioned would need a picture to identify which set up for sure you have.:biggrin2:

Not hard to tell the difference. Most Thermopiles have wires and can be trimmed:

Thank you good sir. You're absolutely right..... Need to lay off the good stuff apparently....

Cheers!

Nope , that is not it . It defiantly is a thermocouple with the thin copper tubing .

Seems to be working fine , now . However , I am thinking of maybe having a new thermocouple as a spare .

God bless
