Hello, I've got an older wood stove that I use to heat the house. I noticed that I'm going through a lot of wood, and can't keep a fire for more than 3 hours. after that I have to completely start a new fire, not even enough coals to ignite. The unit is approx 20 yrs old, and I discovered there is no gasket or provision for a gasket on the door to the fire box. Any suggestions are welcomed, thanks
Joe
