Ww ; The American Heat Preserver Is For true comfort, healthful air, and less fuel expense, install our heat preserver. 1: is the greatest eliminator of cold houses for all time. It turns cold houses into warm homes. It relieves the housewife from the tiresome burden of climbing stairs to watch and regulate the fire. a patented device scientifically constructed to control fire, promote an even, steady heat, and produce perfect combustion in furnaces, boilers and stoves. The American Heat Preserver is installed in the smoke pipe leading from the heating plant to the chimney, requires no attention, and will outlast the heating plant. The drawing power of a chimney is in direct proportion to the warmth of the chimney. The present check draft method allows the chimney to cool; the American Heat Preserver method keeps the chimney at the right temperature at all times. National fuel organizations recognize the merits of this device as a fuel saver and heat conserver. I: works like magic on any furnace, boiler or stove where coal, coke or wood is used. Toe fuel burns slowly and completely generating more heat which radiates into the home instead of shooting up the chim- ney as waste. sss fuel to buy, less coal to shovel, less ashes to carry out. No ashes to sift, no clinkers to break, no constant adjusting of drafts. VIC. J. KILLIAN, Inc. Plumbing Contractors 897 Linden Avenue Hubbard Woods Tel. Winnetka 1260
