Generated explanation

Two capped metal chimneys of different heights extend through a sloped, shingled roof. Exhaust from the lower chimney drifts toward and around the upper portion of the taller chimney. An annotation warns that this exhaust can damage the higher chimney. A horizontal dimension arrow between the chimney walls indicates that the chimneys should be at least 16 inches apart.
