FUNCTION OF CHIMNEYS.
The most common faults in chimney construction are:
1. The use of unsuitable materials. Clay sewer pipe, hollow building blocks, or unprotected concrete should not be used.
2. Improper laying of brick. Brick should not be laid on edge and should be properly bonded. Lining should be used in all brick chimneys the walls of which are less than 8 inches thick. Lack of mortar, especially in the perpendicular joints, ruins many an otherwise good chimney.
