I also have a Beach Furnace that is cutting out in the middle of the night and I wake up with no heat. It seems to work fine once you get it going... any Ideas... on what could be causing it?? Its in a 1985 mobile home running natural gas, in a park setting. I have owned it for 5 years with no problems till now. Serial # 108064, Model MPG-700, 90,000btu, or model 6654-1700, code5179... any help would be great... my email is [email protected]... thanks
