Receiving and Handling

Upon receiving dampers, check for both obvious and hidden damage. If damage is found, record all necessary information on the bill of lading and file a claim with the final carrier. Check to be sure that all parts of the shipment, including accessories, are accounted for.

Dampers must be kept dry and clean. Indoor storage

and protection from dirt, dust and the weather is highly

recommended. Do not store at temperatures in excess of

100°F (38°C).

Pre-Installation Guidelines

The basic intent of a proper installation is to secure the smoke damper in, not to, the opening or duct in such a manner as to prevent distortion and disruption of damper operation. The following items will aid in completing the damper installation in a timely and effective manner.

1) Lift or handle damper using sleeve or frame. Do not lift damper using blades or actuators.

2) Damper (rectangular) has label on outside of sleeve indicating a ‘No Screw’ area. Do not install screws into this area as screws may interfere with unexposed blade linkage and prevent damper blades from opening and/or closing.

3) Damper must be installed into duct or opening square (round) and free of twist or other misalignment. Damper must not be squeezed or stretched into duct or opening. Out of square, out of round, racked, twisted or misaligned installations can cause excessive leakage and/or torque requirements to exceed damper/actuator design.

4) Damper and actuator must be kept clean and protected from dirt, dust and other foreign materials prior to and after installation. Examples of such foreign materials include but are not limited to:

a) Mortar dust b) Drywall dust c) Firesafing materials d) Wall texture e) Paint overspray

5) Damper should be sufficiently covered as to prevent overspray if wall texturing or spray painting will be performed within 5 feet of the damper. Excessive dirt or foreign material deposits on damper can cause excessive leakage and/or torque requirements to exceed damper/actuator design.

6) Caulking is not necessary, however, may be applied to optional retaining angles.

7) The Code Authority Having Jurisdiction (AHJ) must evaluate and provide approval of final installation where variations to these instructions are necessary.

Installation - Failure to follow these instructions will void all warranties.

1. SMOKE DAMPER REQUIREMENTS

Smoke dampers are required to close and prevent the passage of air and smoke through ducts or ventilation openings in smoke barriers. Smoke dampers are also applied in engineered smoke control systems to establish air pressure differentials and thereby prevent the spread of smoke.

2. LOCATION OF DAMPER IN DUCTWORK

Place the damper assembly in its proper position relative to the barrier as shown (in Figure 1). The plane of the closed damper blades must be within 24 in. (610mm) of the rated smoke barrier and before any duct inlets or outlets.
