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.
 
Not sure. You will have to contact the stove manufacturer &/or the remote manufacturer to determine compatibility.
 
It is possible if you understand how it works and have the knowledge to do it yourself. No professional or manufacturer or stove shop is going to help. The liability is to great and the stove shop wants to sell you a new stove. That is how it works across all forums online.
