Question about Williams (5009622) Ceramic Gas Wall Mounted Panel Heater
Jump the two thermostat wires together to test the thermostat. Next, jump the terminals at the heater to test the thermostat wires. If the unit fires, you have found your problem. If it does not, you will need to turn the thermostat to the highest setting and check for 24 volts at the gas valve. If yes, bad gas valve, if no, bad transformer.

Dear Alex191: I am shocked and amazed that the Williams heater company is STILL knowingly and willingly selling faulty direct vent gas heaters. My problems took place in 1988! I bought a 30,000 BTU Williams DIRECT VENT from The Home Depot. I took the time to remove window sashes and run gas line to the Williams heater that I had placed in the window aperture. I was glad to finally have heat and be able to heat the area of the house where I stayed. Then I began to smell gas when the Williams was OFF. I traced it to the area where the pilot light gas tubing entered the combustion chamber. I removed the Williams unit and replaced it with an identical make and model and the SAME THING HAPPENED!!! I sat on my bed and almost cried. I had the gas company come out and they labled the problem as a "fuzz leak". The warranty repairman came out and had no idea what to do. Tightening the retaining nut did nothing. I called Williams and even back then they said that they were aware of the problem. They called me back and wanted to send me a part and asked me, "Can you work on it?" I returned the Williams and bought a Perfection-Schwank CONSOL heater that burns the air in the room and vents horizontally to a 4 inch vertical gas vent and was very satisfied with it. When they went out of business I bought an "Empire" brand gas heater. I don't know if I'll ever buy another direct vent heater from anyone. I will be glad to write an affidavit should you decide to suit the Williams company.

I'm having the same exact problem... At first we thought was the vent... but the way the flames goes out... it seems that there is "not enough oxygen" more than "blown out by the wind"... right after both main & pilot goes out, I can't even light any external flame inside the chamber... and it doesn't feel like the outside cold air coming in... it just feel like there is some sort of gas in the chamber that's so strong, it prevents flame... and the only thing I can think of is that it doesn't have enough oxygen, but too much natural gas, and flame can't sustain.
