Tree limbs and leaves should be at least ____ feet away from the chimney top.

Tree limbs and leaves should be at least 15 feet away from the chimney top to prevent any fire hazards and ensure safe operation of the chimney system. This distance helps to eliminate the risk of combustible materials igniting from heat radiating from the chimney. Additionally, maintaining this clearance allows for proper airflow and reduces the chances of debris obstructing the chimney or flue, which can lead to unsafe conditions such as chimney fires or reduced efficiency in venting harmful gases from the appliance.

Choosing a distance of 15 feet is a standard guideline among safety practices, as it also accommodates various types of trees and their growth patterns, ensuring that over time, branches do not encroach upon the safe zone around the chimney.
