Question about Heating & Cooling

1 Answer

I have a Rinnai Galaxy 21 heater and I need spare parts for it. A Gas guy took the thermocouple from it to look for a replacement part but all I got was a call back saying that the part could not be replaced and I need a new heater. The original issue was that the heater lit up but would extinguish after several minutes. The fan worked fine. It just wouldn't stay lit.

SOURCE: Rinnai Econoheat 850 gas heater

Hi Daryl,

It needs a service. The jets carbon up and when they heat up they stop the gas getting through. If you take it to a Gas Shop they will charge you around 90-00 to service it and all they will do is blow it out with compressed air. If you can get hold of an Air Compressor with an Air Blower on the end you can blow it out yourself. Remove the Gas Hose from the back and place the Air Blower into the hole where the gas goes through and hold down the ignitor switch to open up the jets. Give it a good blow out. Once you have done that give the candles a blow as they eget dirty also. You will see a white dust more than likely come out of them. If you want to give it a good clean out remove the cowling and clean (blow out) the inside of the Heater. The cowling from memory has only about 6 or 8 screws holding it on. That should take the top and sides off. I can't remember if you can remove the lower vent on that model - if so it will only be either 2 or 4 screws. Hope this Helps.

Regards
Bryan

SOURCE: pilot wont stay lit installed new gas valve and new thermocouple

Is this a standing pilot furnace, or electronic igniton?

If standing pilot, does the heater use a fan to blow air through the heat exchanger?

If the answer to those questions is yes, then check that the pilot orifice is not partially plugged and that there is a strong pilot blowing against the thermocouple. If there is, replace the thermocouple. If not, check the orifice again, and check that the inlet screen to the gas valve is not filled with gas line trash.

If the the pilot flame is good and it continues to go out, the thermocouple magnet in the gas valve may be weak. Replace the gas valve as to get just the magnet and coil is not easy.

Reply back any questions you may have.

Dust build up inside the pilot light burner assembly. A clean pilot makes noise and has a blue flame when it is burning. A dirty pilot has a quiet and smaller flame with an orange tip.

This is regarding my Rinnai gas heater Model 1260 S.When On button is pressed, it burns and glows the plate but when released , Gas stopped and it turns off.


problem is proberly the thermocouple burnt out .FSD
(fail safe device) normally you push the button in and the pilot light or flame is ignited,this flame heats the thermocouple that generates a small voltage that holds the gas valve open.
if the thermocouple is burnt out or not set correctly in the flame or the pilot flame is to small , as you say when you release the button it goes out, looks like you need a new thermocouple.

We have not turned the heater on since 2010. it is a gas with fake logs.A rennai flame fire inbuilt standards. Husband says the thermacouple is not working? what do you recommend?


Stephanie, I 'm not sure how it was determined, that your direct-vent gas fireplace needs a Thermocouple? As a dirty pilot light will also mimic a faulty thermocouple. In addition, if the fire hasn't been used since Winter of last tear, and the gas line to the unit has been turned OFF since then, the air in the gas line must be purge, before the Pilot will light and hold.

If all of the above can safely be ruled out, then the thermocouple should be replaced. The facing of the fireplace will have to be removed, to access the Thermocouple.and it's connections to the gas control valve. You didn't mention which Rinnai Gas Fireplace you have, but most if their units, use Thermocouple part # 90193475. If you're going to replace it, it would be a good idea to also replace the Thermocouple Retainer, part # 9377.

I hope this helps you to further troubleshoot and solve the problem. Please let me know. Thanks.

I "think" I have pinpointed the problem but want confirmation before I buy this part. the sequence of "lighting " the pilot is working fine and the water flow is circulating as it should. when I "turn"...


To keep the Pilot running... TYPICALLY the instructions say hold the pilot down for 30 seconds to allow the thermocouple to assume control... If extending that 30 seconds a wee bit does not work and your "pilot" keeps going out...

You have indeed found your "trouble"

The obvious defferences being length (first
(see generic parts below)

Follow the instructions on the replacement &
- DO NOT overtighten...!!

NO HOT WATER N THE PILOT NOT LIGHTING UP


The thermocouple has gone bad.The thermocouple needs to be directly in the pilot flame.When the thermocouple goes out,the flame most of the time will have burned the thermocouple tip a way.If it was not for this devise,the gas would exscape,and fill the home up.This is a safety feature.
