Instead of the requirements for floor protection specified here, a floor protector listed by a recognized testing laboratory and installed in accordance with the installation may be employed. Legs installed by the manufacturer should not be shortened or removed, nor should any item be placed where it will interfere with circulation of air under the stove. Connecting pipe Stoves are connected to chimney inlets with uncovered sheet metal pipe known generally as stove pipe. This pipe is usually 6 or 8 inches in diameter and should be constructed of 24-gauge or heavier metal. Select pipe size to match the outlet size of the stove.
Maximum efficiency is obtained when stovepipes are as short and as straight as possible.
In no case should pipes be longer than 8 to 10 feet or contain more than two 90-degree bends. Avoid horizontal runs. Assemble joints in the pipe so that they will funnel any liquid creosote accumulating in the pipe back to the stove where it will burn. Joints should fit tightly to eliminate entry of room air directly into the chimney system. Use furnace cement to ensure tightness.
