Question about Procom MN300TBA Heater
I have a RITETEMP RTN300TB vent free heater in my garage, approximately 800 sqft. I have had it for about 5 winters now, and last winter on occasion it would just shut off by itself. I would come home from work, pull in the garage, and the heater would kick on, then I would come out to the garage 8 or so hours later, and the heater would be off, including the pilot. I would relight the pilot, and it would be fine for a week or so. It is doing it a lot more this year. I took it apart, and cleaned the t-couple, and the pilot light burner orifice. After reassembly, I lit the pilot light, and the heater kicked right on, thought my problems were over. Well, when it got to temp. and shut off, the pilot shut off also. I tried relighting the pilot, and it seemed as though the gas was too high of a psi. and it kept blowing out the pilot. I was working in the garage, and did not have any symptoms of CO poisoning, although I have never found the "oxygen depletion sensor" so I dont know if that is my problem. Please help, as I use this heater to keep my garage "warm" during the winter to keep our trucks thawed out.
I am not familiar with this heater but it sounds like it could be a blockage in the main gas line into the heater or perhaps a blockage to the pilot gas line and maybe starving for gas. Best bet first is to check the main gas line from the heater. Easiest way to do this is to remove it from the heater and blow it through with compressed air. Then try the heater again. If that doesn't fix the problem then you can try blowing compressed air down through the pilot line. Could be a little dirt creating a blockage there. Then try the heater again. If it still does the same thing then try removing the panels to expose the heater's piping. If you can remove the main pipe into the heater from the gas and blow compressed air through it it should clear any obstruction from both the main line and the pilot. If this doesn't work then I would think you have a more severe problem and will need to take it to your local Heater Repairer. Hope this helps.

sounds like your thermacouplar is going out and needs replaced. Sometimes these will act like they are working fine , but when the pilot stays on for awhile and later goes out it is a sure sign that it is bad
