No Connecting Duct or Transfer Opening

Openings where duct does not attach on either side will not 
require a breakaway connection. Transfer openings are typical of 
a non-ducted installation (see 

Figure 24

).

  •  Sleeve may end flush with the rated wall/floor on both 

sides

  •  Refer to Securing the Damper/Sleeve Assembly to Wall/

Floor Openings for securing retaining angles to the sleeve.

Damper Commissioning and Periodic Testing

The International Fire Code (IFC) requires fire dampers to be maintained in accordance with NFPA standard 80 and 
smoke dampers to be maintained in accordance with NFPA standard 105. NFPA 80 and 105 define the frequency 
and method for periodically testing life safety dampers.
NFPA 80 & 105 do not require heat to be applied to a damper’s fusible link or thermostat during periodic testing. 
Electric or pneumatic actuated dampers are required to be tested by temporarily removing electrical or pneumatic 
power from the actuator to ensure the damper fully closes and then fully opens once power is restored. Mechanical 
and gravity operated dampers utilizing a fusible link are required to be tested by removing the fusible link and 
allowing the damper to fully close and then manually reopening the damper. Re-install the fusible link.
Greenheck’s life safety dampers shall not be tested by applying heat with uncontrollable heat sources (i.e. heat guns, 
torches, etc.) as this can permanently damage the thermostat or other parts of the damper.

Damper Maintenance

Dampers do not typically require maintenance as long as they are kept dry and clean. If cleaning is necessary, use 
mild detergents or solvents. If lubrication is desired for components such as axle bearings, jackshaft bearings and 
jamb seals, do not use oil-based lubricants or any other lubricants that attract contaminants such as dust.

Damper Troubleshooting

The following is a possible cause and correction list for common concerns with the dampers.

Symptom

Possible Cause

Corrective Action

Damper does not fully 
open and/or close

Frame is 'racked' causing blades to bind 
on jamb seals

Adjust frame such that it is square and 
plumb

Screws in damper linkage

Damper installed too far into wall. Move 
out to line as designated on damper label

Contaminants on damper

Clean with a non-oil based solvent (see 
Damper Maintenance)

Link separated

Heat

Replace link
