To see the oven damper, take off the lid nearest the stove pipe and watch the direction of the flame. The handle to the oven damper may be at the side of the pipe on top of the stove or at the front of the stove under the top near the reservoir. Closing this damper causes the hot gases from the fire to go back over the top of the stove down behind the oven, turn under the oven and come up the chimney. Good stoves are constructed so that the hot gases come in contact with every part of the oven. This makes a longer journey for the gases, but, if the drafts in the front of the stove and chimney are properly adjusted, the gases will make the circuit without forming soot. [Illustration: FIG. 2. Drafts and dampers in stove-pipe.] 4) A damper in the stove pipe (Fig. 2) for letting air from the room into the pipe serves to check the burning of the fire by taking the place of the draft thru the stove. 5) A damper, or shutter, found in the pipe or chimney of most stoves, when closed, checks the draft up the chimney, and, when open, lets it pass freely. 6) The reservoir damper, found on some stoves having reservoirs, lets the hot gases pass next to the reservoir when open and prevents this when closed. =4. Starting the Fire.= If the stove has a reversible grate, see that it is adjusted to suit the fuel before building the fire; then adjust the drafts. Open the draft below the fire box, the oven damper, and the shutter in the chimney; close the draft above the fire box, and the draft which lets air from the room into the pipe, so that the air may pass up thru the fire box and directly up the chimney. Some chimneys produce such strong drafts that the shutter in the chimney has to be kept closed most of the time, even when starting the fire. After the fuel has become ignited, the draft below the fire may be partly closed so that it burns less rapidly. If the fire is to be used for heating water or food on top of the stove, it is now ready for use. If it is still burning too rapidly, the draft may be entirely closed, or the shutter in the chimney partly closed. If at any time the stove smokes, the shutter or drafts above the fire may be closed too much and should be opened enough to let all the smoke pass. Adding too much fuel at one time and not spreading it in a thin layer over the entire surface of the fire may cause the stove to smoke. =5. Keeping a Fire.= If, after a fire has been used, it is wanted for use later, close the draft below the fire box, open the one above the fire box, or, if there chances to be no draft here, tilt the lids on the stove to let in the air; close the shutter in the chimney and open the draft in the pipe that lets in air from the room. With the drafts so adjusted, the fire should keep a long time, as it will burn very slowly.
