When dry sprinklers are connected to wet pipe systems protecting insulated freezer structures, how must the clearance space around the sprinkler be managed?

When dry sprinklers are integrated with wet pipe systems to protect insulated freezer structures, it is crucial to seal the clearance space around the sprinkler. This sealing is essential to prevent any moisture or condensation from affecting the functional integrity of the sprinkler system. If the area around the sprinkler is left open or inadequately sealed, cold air from the freezer can lead to the formation of ice, potentially causing blockages and impairing the sprinkler's operation during a fire event.

Sealing the space ensures that the cold conditions of the freezer do not negatively interact with the components of the sprinkler system. Proper sealing techniques help maintain the intended environment, ensuring that the dry sprinklers remain effective and that there is no risk of water damage or freezing that could render the system inactive. Therefore, managing clearance by sealing it is a critical practice in maintaining the reliability and safety of the sprinkler system in insulated freezer settings.
