I have a vermont castings radiance gas stove. The pilot wouldn't stay lit once I released the knob(had the gas off to it for the summer - just turned it back on) so I cleaned the tc/tp with an emery cloth. The pilot is lit now, but when I turn it to 'on' the pilot goes out. Any ideas? I'm a newbie - let me now if there is more info needed. Thanks for your help.
