The stove is normally pretty quiet when it's burninging but it woke me up the othernight. The flame looked kinda blue and the stove sounded more like a blowtorch sound. I shut it off with the remote and turned it back on and it was fine but it did do that once before. I thought it was maybe running out of gas but the tank is still at 30%. Could it be and impurity in the propane or is the stove dangerous ? I have no idea who even fixes them in CT. I bought it form the Preston Trading Post but they do not service them. I am going to call Jotul tommorow. I am afraid to use it. Is this normal ?
