I have Wiiliams direct vent wall furnace. I smell
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.
Williams wall heater in California
Yes it sounds like it does. There should be no carbon monoxide in the environment. I am sure you know how dangerous CO is? Can your gas utility company or a registered gas technician to check it. The heat exchanger should be a replaceable part.
Adding a photo to my inquiry?
That probably means too much fuel or not enough air for correct combustion to take place.
I would check its settings.
The williams wall heater keeps
My heater has been doing the same thing. You do not need to remove the grille cover to reset it. Poke a small screwdriver through a vent slot and reset the small red button. Allow the heater to cool off before resetting. When the vent reaches 260 degrees, the switch cuts off the furnace. The solution is to place a fan pointed at the top and side of the furnace so it doesn't get scorching hot. It happened to my furnace continually when a strong, cold west wind was hitting my roof-top vent. When the storm passed after two days, the furnace operated normally again.

Re Williams 3003622 Heater Please advise how to
You will first need to turn the control knob to pilot. Then depress the control knob button and hold it. Then press the push button piezo igniter several times until pilot lights or open pilot inspection cover and manually light pilot with match/lighter. You may need to hold the control knob for at least a minute. Then release the control knob and if the pilot stays lit then turn the control knob to on. If it does not light then repeat the process again.
Gas wall furnace pilot goes out when burner turns off.
When the main burner turns off, does it make a whoosh or pop? If so, this would be the issue causing the pilot to be disturbed. And have you tried to adjust the pilot/thermopile strength, if possible? A stronger pilot may help. Now if the main burner slowly goes out, and the pilot also slowly goes out, and also slow to ignite, and you've replaced about everything else, it may be the gas valve itself that has/is giving up. Gas is impure and causes a sticky residue. And if the main burner is "slow to act", this tells me the piston that's inside the valve is slowly opening or closing, and may be the reason the pilot is acting up. Make sure you check the outlet to your flue pipe also for obstructions. If the unit doesn't vent properly it can have more heat in the flue. That heat can have a downward rush when the burner goes out, kinda like forcing air through a clogged tube. And when you quit forcing the air, some of it comes back at you. Before condemning the valve try to check all else as you have done with the thermopile and such. Please work safe and I hope this helps.
Unable To Keep Pilot Light Lit!
I have a Williams top vent gravity wall furnace (model 5009622) and I had the same problem. I had to take the cover off the furnace -- screw on top and two at the bottom (open the access door and there is one screw on each side) to get to the reset button for the vent safety shutoff system. On my furnace it's on the left side toward the top of the unit. I pressed the little red reset button and it's been working ever since. If your furnace is properly installed and doesn't have bird's nest in the chimney, it should work fine. Good luck!
