HEATILATOR ELECTRIC FIREPLACE INSERT ELECTRONIC BOARD AND WIRES SHORTED OUT AND BURNED. WE WERE PARKED IN A CAMPSITE AND LUCKILY SITTING THERE AS SPARKS FLEW PLUS WIRES SMOKING. I UNPLUGGED UNIT SO NOTHING ELSE WOULD BURN. IT DID NOT THROW A FUSE OR BREAKER. WIRES WERE JUST HANGING FROM HEATING UNIT. *JS
