I have a natural gas fireplace (was converted by the fireplace people from LP} and is controlled by a switch on the wall. The fireplace now doesnt respond to the switch and is on all the time. There is a standing pilot light, but now its the full fire conintuously. I turned the knobs on the control valve to get it back to just a pilot light but ultimately turned the gas isolation valve off for now.
I cant see the control valve numbers as I think its on the bottom. Looks to be a millivolt style.
Should I just replace the valve with a similar valve?
