More about the Franklin Stoves [Under date of Dec. 8, 1749, is an extended description of the Pennsylvania Fireplace with a reference to Franklin’s pamphlet of 1744. Kalm continued his discussion the next day, writing particularly about the criticisms and objections raised against the stove, mentioning especially the difficulty of cleaning the chimney and the consequent danger of fire, and the fact that, in the view of some people, “the stoves gave too much heat.” Franklin had loaned one for the winter to Kalm, who found it very satisfactory.] The chimney is seldom cleaned more than once a year, but Mr. Franklin was in the habit of setting fire to a sheet of paper every fortnight and let it pass through the flue leading to the stove and so burn off the soot there also. If the stove is narrow it is not so easy to sweep the chimney, after everything is closed up by masonry; but Mr. Franklin had a brick removed beside the stove, let a man pass down through the chimney, clean it, and when he reached the bottom near the stove had him force the soot through the hole made by the removal of the brick. When this was done the brick was replaced. Where the hearth is broad the stove is placed on one side of it, and a door made on the other through which the chimney sweep can enter and do his work. To get fresh air into the stove of a house with no cellar, and where no outside air is wanted, Mr. Franklin this year had had the stove in his own room set on a rim of masonry six inches from the floor, with an opening through the bricks on one side to let the cold air near the floor enter, pass through the air-box, where it was heated, and then pass through the holes on the iron sides of the stove into the room, etc. This brought about a constant circulation of air.
