I have done some research and the excact replacement valve is out of date. There is a replacement control valve that is available. I would need to know more specifics as the model # XXXXX your valve is a basic number. there are more numbers that determine gas type, btu rating, pilot style,ie. millivoltage, or 24 volt. and inlet and outlet size of gas lines to valve. It looks like the cost is just under $200 for the valve that I guessed it may be. Please reply if you need more specifics. You should be able to go to a local fireplace retailer or heating company to have them cross reference the info and get a valve ordered. Does your valve look like this?
