I have a Pleasant Hearth 30K BTU ventless gas (propane) stove fireplace......The controls are on the bottom of the stove. I would like to change the control valve to a millivolt valve. Does anyone know if there is a millivolt valve that is a direct replacement for the EuroSIT 630 (0630560) that comes standard on the stove?
 
Can’t be done. Millivolts are generated by a thermopile in the pilot assembly. Your unit doesn’t have one AFIK. You only have a thermocouple in there. A thermocouple generates about 30 mV. A thermopile generates about 550 mV. Maybe someone else will chime in here to refute what I‘ve said, but I don’t think that’ll happen. Your unit is not tested for the modifications you will need to do & it will not be safe to operate.
