For the VK470 Residential Pendent Sprinkler, what is the minimum distance from the ceiling for the deflector?

The VK470 Residential Pendent Sprinkler requires a minimum distance of 1-1/8 inches from the ceiling to the deflector to ensure proper function and performance. This specification is critical for the effective operation of the sprinkler system, as the distance of the deflector affects water distribution patterns and overall efficacy in suppressing fire.

When the deflector is positioned too close to the ceiling, it can hinder the sprinkler's ability to distribute water evenly across the protected area, potentially leading to reduced coverage and a higher risk of fire spread. The 1-1/8 inch distance is designed to optimize the sprinkler's performance by allowing for an adequate air gap that facilitates the proper dispersion of water droplets in the event of activation.

This specific measurement aligns with installation guidelines and best practices outlined by manufacturers and fire safety standards to ensure that the sprinkler operates effectively in a residential environment. Adhering to this minimum distance is essential for compliance with safety regulations and ensuring that the system functions as intended in an emergency situation.
