OK.Thank you so much for replying. I have taken a few pics of the Gas Valve. It is from a ducted heating system. Hope you can help with finding one that matches. I went to my local HVAC dealer and he sold me a Honeywell V800 A 1179. He said it would do, however the wiring on it is wrong, even though it looks similar. I have googled for hours trying to find one. That is how I stumbled across this site. Hope you guys can help me.
Thank you Plumbers Crack. Believe it or not, the rest of the system is in perfect order. Thats why i want to replace the valve. I suspect the cover was left off the unit for a while before I moved in.
