Minecraft wiki entry for Furniture, associated text: To build an old-style brick built fireplace, you will want this next to a wall. First, dig a 3 block deep hole. After that, add netherrack at the bottom and light it up. Third, place netherrack on the top of the hole. Next, place a brick on both sides of the fire and put another brick on top of those and in the middle of the ones in the top. Repeat in front of the bricks so you cannot throw things in the fire. This part is optional. If you want to add a chimney, add bricks on the top to the sides and the front of the fire. Keep adding until you reach your roof and then break the area where the fire is. Add 2 - 3 more levels of the chimney on the roof. Finally, add netherrack on your roof level and light it up!
