TYPICAL FACTORY BUILT CHIMNEY INSTALLATION
FLUES AND CHIMNEYS – SOME BASIC PRINCIPLES
1. The chimney top should be higher than any other part of the house or any nearby surrounding objects – see
installation code.
NOTE: The chimney must be at least 3 feet above the highest point where it passes through the roof of the building
and not less than 2 feet above the highest roof surface or structure within 10 feet horizontally. Not more than 8” of
chimney cap above the top of the flue may be considered in computing this height.

BASIC RULE FOR CHIMNEY TERMINATION HEIGHTS ABOVE ROOF
2. A straight chimney is best.
3. A chimney should be smooth on the inside.
4. The flue pipe and chimney should be inspected periodically and cleaned if necessary.
