I've a new Dyna Glo ventless heater and the pilot does the same as your example at 0:34 sec it begins to crackle/sputter slightly then the flame tip extends, the gap from pilot tube widens then it goes out. There is adequate oxygen/ventilation in the room and other gas heaters equipped with ODS function fine. I've cleaned the pilot tube for any manufacturing debris and noted that if you partially obstruct the pilot tube 'vent' hole on the side the pilot behaves normally without sputtering and will remain on....is there an adjustment for the hole in the side of pilot tube?
There is no adjust but after a lot if frustration and 2 new wall heaters by Mr. HEATER, I bought an EMPIRE ventless wall heater and in identical situations it stays burning and is working great. I was told the cheap $200 stoves you'll always have trouble with.
My fireplace used to run just fine. It is an electronic ignition with a remote. Now when I start it, it cycles through everything, lights just fine, burns for about 8-10 minutes and then shuts off. I have replaced the thermocouple but it is still doing the same thing. The gas company where I purchased it 5 years ago says they no longer service ventless gas fireplaces. So I am at a loss. I will try to run it with the damper slightly open, to see if it makes a difference.
This is an excellent demonstration- but *vent-free heaters* can produce *lots* of _carbon monoxide_ *without* shutting off via the *ODS.* Look for any sputtering, inconsistent burning or _yellow_ flames and a *carbon monoxide* detector is a _must_ with _any_ oil or gas heater.
no, no, no, no. The oxygen partial pressure is lower, but the percentage is the same. How the lower pres affects burning - and thus the oxygen sensor, I don't know.
To bypass these you wrap a bit of wire around the thermocouple and have a bit of it extend into the path of the flame. The wire transfers the heat to the thermocouple and the system keeps running. PS this is a terrible idea the only reason I know this is because bad gas quality can mess with the flame making the oxygen sensor misread and shut down your heater.
Buy an Empire heater. Trust me, the cheap heaters are prone to this. My new Empire is AMERICAN MADE and is designed to function at high altitudes too. I wasted $400 on 2 Mr. Heaters before I was told this.

I have a question for you if you get this comment

Simple to the point spot on! Thank you
Your comment. Spot on
How do these operate in high altitudes like in Bolder CO? The normal oxygen level there is approximately 16%.
no, no, no, no. The oxygen partial pressure is lower, but the percentage is the same. How the lower pres affects burning - and thus the oxygen sensor, I don't know.
Would it make a click sound like a snap switch?
the sound is fairly quiet but there is a dink sound
Thanks a lot.

This keeps happening to me how do i solve it open a window or will a fan blowing air work ir whats the best solution?
This sensor has rendered portable propane heaters like The buddy heaters useless
Buy an Empire heater.

keep a window cracked open if it continues to happen you might have to open window more depending on wind direction at window
Good video
