FIRE DAMPER INSTRUCTIONS
1. The FIRE DAMPER is accessible by removing the TOP PANEL
The FIRE DAMPER sets in the DAMPER SUPPORT and may be
removed by lifting straight up.
2. The FIRE DAMPER normally needs no maintenance. If it
becomes heavily contaminated with dust and/or grease, it must
be
replaced.
3. If the FIRE DAMPER malfunctions or if the fusible link releases,
the manufacturer recommends that the entire FIRE DAMPER
ASSEMBLY
be
replaced.
4. Reinstall the FIRE DAMPER with the “THIS SIDE UP FOR
HORIZONTAL MOUNTING” arrow pointing away from the
BLOWER.
IMPORTANT:
Replace the entire fire damper
assembly if the link trips, or if the
damper mechanism becomes
heavily contaminated with dust
and/or grease.
While the fusible link alone may be
replaced, once the damper has
tripped it may no longer function
reliably.
Contact factory for pricing and
availability.
