When I had my stove installed last year the installer put in a cheap 250 millivolt thermostat that isn't worth a dime. The owners manual says you can use a 250 or 500 millivolt thermostat on the stove. But I can't find any out there. They are all 750 millivolt. I see they have a remote one on their web site but who wants to pay that kind of money when a wall unit would work just fine. Anyone know where I could get a thermostat and will a higher millivolt work?
