General Information

1. ► Closer Spring Adjustment (not shown):
• Affects the entire cycle of the door closer movement.
• Used to size closer for application requirements.
• Determines the amount of force with which the door closes and the amount of force required to open the door.
• Adjustable to compensate for door size and draft conditions.

2. ► Backcheck Valve:
• At approximately 70° of the open cycle, the backcheck valve begins to slow the door’s motion.
• Prevents the door from slamming into the door’s stop.
• Valve is used to control the intensity of the backcheck.
• Note: a positive stop is required, backcheck cannot be used as a stop.

3. ► Delayed Action Valve (optional):
• Holds the door in the open position momentarily.
• 20 second minimum hold open delay.
• The feature is available for all applications and arms.
• Beneficial when moving carts or objects thru door opening and ADA applications.

4. ► Closing Speed Valve:
• Controls how fast the door closes to approximately 8” from the closed position.

5. ► Latching Speed Valve:
• Controls the speed of the door during the final 8" of door swing.
• The force the door closes with is controlled by the closer spring.
• Note: This adjustment is critical for door latching.

Fire Rating Note: Any retrofit or other field modification to a fire rated opening can potentially impact the fire rating of the opening, and Sargent Manufacturing Company makes no representations or warranties concerning what such impact may be in any specific situation. When retrofitting any portion of an existing fire rated opening, or specifying and installing a new fire-rated opening, please consult with Penner to ensure compliance with all applicable codes and rating.

Standard Applications

This closer mounts on the hinge (pull) side top rail of door. It can be used on interior doors opening in or out and exterior doors opening in. The cover projection normally limits the door opening to a maximum of 160°.

Top Jamb Applications

The closer is mounted inverted on top casing above stop face of door. As the door swings, the closer arm swings with the door. For use on interior doors opening either in or out; and exterior doors opening out.

Parallel Arm Applications

The closer is mounted on the top rail on the stop side of the door. As the door opens, the closer swings with the door and gives full headroom in the door opening.

Track Type Applications

The closer is mounted on the door. As the door opens, the closer swings with the door. For use on interior doors opening in or out. This application affords a variable hold-open feature which is available on order.

ADA Compliance

The 351 door closer is designed to meet the opening force requirements established by the Americans with Disabilities Act, defining 5 lbs. of opening force for interior and 8 lbs. for exterior doors. An adjustable spring design affording easier access and allowing exterior doors control is used. Where excessive draft and pressure conditions exist or when extra heavy doors are used, spring should be adjusted for stronger setting. Meeting ADA requirements can be achieved at all applications with simple spring adjustment. Various field conditions (drafts) exist that make the use of ADA adjustments ineffective. When these conditions exist, refer to SARGENT 2600 auto operator.
