Deflector location must be within how many inches from the wall?

Explanation:
In NFPA 13R low-rise residential systems, the spray pattern from a sprinkler must reach into the space near walls and corners. Keeping the deflector within six inches of the wall ensures the water pattern properly intersects the wall and protects the adjacent area, providing adequate coverage at the perimeter. If the deflector is farther than six inches, the spray pattern can become distorted or fail to reach the wall area, leaving a gap in protection near the boundaries. The 6-inch distance corresponds to 152 mm, and being within that limit (closer is acceptable) ensures proper distribution.
