"HOW DO YOU RUN A STOVEPIPE THROUGH A COMBUSTIBLE WALL OR CEILING?
You don't. But if absolutely necessary, the following are approved methods:
- Build a 3.5-inch thick brick masonry wall framed into the combustible wall, with a 12-inch minimum clearance from the clay liner to combustibles.
- Use a solid, insulated, listed factory-built chimney, with a 9-inch air space to combustibles.
- Use a 24-gauge sheet-steel chimney connector with ventilated thimble, plus 6 inches of glass fiber insulation.
- Use a solid, insulated, listed factory-built chimney over a 24-gauge chimney connector, with 1 inch of air space, plus 2 inches from outer wall of chimney section and combustibles.
