What is the required distance of a sprinkler from a heat source in residential kitchen areas?

In residential kitchen areas, the required distance of a sprinkler from a heat source is 9 to 18 inches. This regulation is designed to ensure that the sprinkler can operate effectively without being adversely affected by the heat generated from cooking appliances. Sprinklers need to be placed at a distance that allows them to detect an increase in temperature due to a fire, but too close proximity can lead to premature activation or ineffective operation, especially in cooking environments where high temperatures are common.

Maintaining this specified distance is important to ensure the proper functioning of the fire suppression system and to minimize the risk of both false alarms and potential damage to appliances. This distance is established based on safety standards and practices that aim to balance effective fire suppression with the practical conditions found in residential kitchens.
