I purchased a vent free gas fireplace this past spring when they were one sale at a local store and it seemed to work fine with the little testing I did to make sure it worked properly. I turned it off shortly after installing it because I wasn't going to use it until the this winter.
This year when trying to use it, the pilot light wont stay lit half the time. In the times when the pilot light will stay lit long enough for the gas bar to ignite, the fire will cut itself off shortly thereafter and the pilot light will go out again. The only time I can keep a fire going is if I turn the heat all the way up and it works until it reaches the right temperature to cut itself off. When it does cut itself off the pilot light goes out again.
I'm guessing (although I don't know for sure) that it has something to do with the fireplace not being able to detect a flame and its cutting itself off as a protection mechanism. Unless I go full force on the temperature setting which generates enough heat where that isn't a problem. Can anyone give me any feedback on what exactly could be going wrong and what I should take a look at?
I have a vent free ProCom modle #FBD28T. Mine has done this also a couple of times. I believe it was be due to air being trapped in the gas line. Once I ran the unit for several hours, the pilot stayed lit and the unit worked as the manufacturer intended. I suggest making SURE all the air has been blead from the gas suply line.
The idea of purging the line of air seems faulty: 1) there has been pressure before, so any significant amount of air would have already been "pushed out", 2) purging is commonly done by leaving the line unhooked and then opening the valve - gas flowing out - making getting a nice BOOm! possible., 3) air is itself partially combustible and should have been burned up already.
I would look at the gas flow regulator. Contact the store and manufacturer immedaitely!

My vent free gas fireplace pilot stays lite all winter long. Comes spring when I would like to use it to save on my fuel oil the pilot will not stay lit. This seem to happen every year. Anyone know why?
The reason the pilot goes out on mine is that sometimes when the valve turns on because the thermostat wants heat the burner takes too long to ignite causing a buildup of gas, then when it does ignite the resulting WHOOOOSSHHHH blows out the pilot, the burner flame goes out and the gas then turns off and the heater is without the pilot running. Poor pilot to burner ignition design.
Mine just started doing the same thing today.
Pilot stays lit until I turn on the heat then it goes out.
Most likely the thermocouple.
