Now that you have your fire going, you need to keep your eye on it and maintain it. If you want to have a fire that burns all night long, need to add firewood to it as you go. You will want to add just a piece or two at a time. You want to make sure the fire doesn't get down so low that you would have to relight it. When you open your fireplace you will need to be very careful because there could be many hot places on the fireplace itself like on the screen. You may also want to get your poker in case you need to shift some of your logs around. So all you are going to do is take an extra piece of wood and put it on the fire real quick. Again you will want to arrange it where it locks the heat in so everything ignites real well and you should have a nice fire for hours to come.
