WOW GOD IS GREAT. THIS IS WHY I AM STILL FREEZING IN MY HOME. I HAD A FIRE IN THIS THING THAT BURNED A WHOLE IN THE COVERING FLAP OF SOMETHING AND UP THE WIRES. I SHOULD HAVE GOTTEN A PICTURE OF THE FLAP. OH WELL I THINK THESE PRETTY MUCH SUMS IT UP. THERE IS A SAFTEY DEVICE THAT SHUTS OFF THE HEATER SO THE FIRE DOESNT GO IN THE HOUSE. I PUT MY MICROFLEECE SHEETS ON AND WAS SOO TOASTY ALL NIGHT. HARD TO GET MY SELF UP IN THE 55 DEGREE HOUSE. BEUTIFUL WARM DAY OUTSIDE. HOPE ITS NOT TOO LONG BEFORE THE VALVE COMES IN.
