ADJUSTING THE DAMPER BLADE POSITION:
The fire damper fusible links, springs and cable blocks are all accessible through the front on the hood. For filter hoods
remove the baffle filters under the opening of the duct collar(s) of the hood. For dry extractors and cartridge remove the
inserts under the opening of the duct collar(s) of the hood.
A single, double, and triple fusible link assembly is shown above. The blade
position is adjusted by removing the fusible link/cable and block assembly
from the damper pin. The fire damper will close and the complete assembly
will hang loose from the spring. Loosen the set-screw on the adjustable
block and pull the stainless steel cable through the block to open the damper
or release cable from the stainless steel block to close the fire damper.
Once the correct position is reached, re-tighten the set screw on the
adjustable block and re-ached the fusible links on the damper pins.
The single fusible link damper has one block to adjust. The
double fusible link damper has two blocks to just and the
three fusible link dampers have up to four blocks to adjust.
