SOURCE: Dayton Infrared natural gas heater ignition/flame sensor

Yes, the flame sensor is part of the intermittent pilot assembly. Check the following: make sure all grounding wires are secure and no corrosion is built up on them. Clean or replace the pilot assembly, also clean out the orifice with a very small drill. Make sure the sensor is in the flame and make sure the pilot tube is not leaking gas reducing the gas pressure at the pilot.

If it continues, you will have to replace the ignition control.

SOURCE: Gas log will not stay lit for more than 5 minutes

after you relight have you tried to leave the gas valve on pilot for 10 to 15 minutes so the themolpile warms up enough to send mil-volt signal. you also have a thermocouple that senses flam so if the flame is not hitting that just wright it will shut off. Is this fire place ran off a thermostat or a on off switch. If you are running off a thermostat then i would try to find on/off switch and try that. You might have to change pilot assembly out.If you do this and don't have manual i would take a picture of the log set up so you put it back together. Make sure all connections are tight when you go back together

Reliant 501 Natural Gas won't stay lit


Reliance water heater?
Thermocouple is good if the pilot stays lit continuously.

501 is older model. Unknown if this unit has FVIR protection and sealed combustion chamber or open air intake on front of unit.
http://waterheatertimer.org/pdf/Reliance-2006-Service-Handbook.pdf

With FVIR protection:
Get more fresh air to the unit.
Clean the flame arrestor screen.
Test and replace the thermocouple:
http://waterheatertimer.org/How-to-test-water-heater-thermocouple.html
Inspect and clean burner and combustion parts
Test gas pressure, bleed air out of gas line.
Replace gas control valve.
Test draft air by lighting match and see if smoke is pulled into the vent pipe at draft hood on top of tank.

The pilot won't stay lit on gas hot water tank.


Make sure thermocouple tip is seated inside the burner flame.
Make sure thermocouple is not overtightened. Finger-tight + 1/4 turn.
If the pilot lights, then ECO energy cut off is not tripped, but gas control valve might be bad.
Check color of pilot flame: it should be strong and clear blue.
If pilot flame is weak, or color of flame is yellow-orange: Clean pilot orifice and burner and combustion parts on yearly basis.
Clean air intake screen if applicable.
Increase air supply to water heater. Open a window and see what happens.
Check for adequate draft going up chimney using match under vent hood to see if smoke drafts immediately upwards.
Bleed air out of gas line.
Check gas pressure.

I have an old whirlpool gas water heater and the pilot will not stay lit.


Suspects include bad thermocouple, thermocouple slipped down and not in pilot flame, dirty combustion parts and pilot tube, dirty air intake, backdraft caused by other vent fans pulling air down water heater vent, water dripping down vent because of poor venting, air in gas line, low gas pressure, bad gas control valve, hot attic environment, tight house not allowing enough air:

Rheem 22V50F1 pilot won't stay lit. Changed thermo couple & it lit, ran then went out. Let it sit overnight & it lit, ran then went out. What next? p.s. The unit is 5 years old. Thanks


If pilot lights and flame is robust and clear blue, and pilot goes out later, then some suspects can be excluded: air in gas line, low gas pressure, thermocouple is overtightened (finger-tight + 1/4 turn), thermocouple not positioned correctly in the flame, dirty pilot tube.
If flame is yellowish and small: then clean pilot tube and combustion parts.
http://waterheatertimer.org/How-to-install-gas-water-heater.html#clean
Remaining suspects can include: air in gas line, low gas pressure, bad gas control valve, tight house so household vent fans pull air down water heater vent that blows out pilot, hot attic with inadequate ventilation, water dripping down vent.

Pilot light keeps going out I cleaned pilot loght has a good flame amd I replaced the thermocouple


Suspects include: bad gas control, air in gas line, water dripping down vent, poor air supply, dirty air intake, very hot attic, negative pressure caused by tight house and other venting appliances and vent fans that cause backdraft down vent. Or combination of these problems.

Reliance 606 natural gas water heater - model #640YORT - water does not stay hot. pilot has to be clicked to heat and then u can use hot water til tank empty and it will not continue to heat water.


If I understand correctly, the pilot light is not staying lit.
You light the pilot and water in the tank reaches temperature.
Once hot water is gone, then pilot light has to be lit again.

Gas pressure is good, and gas is flowing.
Thermostat is working at high end because it cuts off heating.
Vent is working because tank heats up.
Air intake is working.

Gas control thermostat might not be reading low temperature. Replace gas control valve.
Pilot tube might be dirty. Clean burner parts and combustion chamber, and air intake, and vent.
Backdraft might be blowing out pilot. Check for constant updraft by running water heater 5 minutes, and then light match under vent hood and see if smoke goes up.
Very hot air can put out pilot, especially when water heater located in attic. Add ventilation.
Improper vent might have water dripping back down into combustion chamber and putting out pilot light and rusting out the parts. Inspect for rusted parts and water.

I have a Jayco pop up with an Atwood water heater, serial # 37C14U-5. My problem is two-fold. The water heater pilot doesn't stay lit after initial run, and propane is leaking out of the vent on the...


Leaking propane is red flag #1 and fire hazard.
Immediately update your insurance and then turn off gas.
If pilot is not staying lit, then gas leak can be cause of pilot problem since pressure on the line is reduced.
Other causes include bad gas control valve, air in the gas line, bad thermocouple, burner parts need cleaning, or all the above.
After fixing leak, replace thermocouple, clean combustion chamber and burner parts, and bleed gas line to remove air.

My Dayton Gas Unit heater will not stay on. The


Have you tried the flue vent? If not, an easy way to check this would be to take the vent pipe off of the unit and see if it continues to have the problem. In most cases, this happens when you have blocked return air or dirty filters, flue blocked, or induction is blocked from switch or housing. One other possibility would be a dirty/clogged a coil which isn't allowing sufficient air to push out causing the limit to trip. I hope this helps somewhat.
