INSTALLATION
1. Position radiation damper on the inlet side of the fan so
that the arrow in the damper will point UP in the finished
installation. Attach the damper to the fan using #8 (M4)
sheet metal screws (provided). There must be a minimum
of two connections on each of two opposite sides.
Care must be taken to ensure that the fasteners do not
interfere with the closing of the damper curtain. For best
results, use mounting holes provided.
2. Position fan/damper assembly so that the inlet face of
the radiation damper is flush with the finished surface of
the ceiling. Fasten fan/damper assembly to the building
structure by driving #10 (M5) minimum sheet metal
screws or #8d minimum nails (hardware not provided)
through the fan mounting brackets and into the ceiling
joists. There must be a minimum of two fasteners on
each of two opposite sides. Ceiling opening must be
no larger than the inlet opening of the damper.
3. New Construction
A housing mask has been provided to keep construction
dust, drywall spray, paint, etc. from damaging the
radiation damper of blower assembly.
a) Bend up the small tab of the mask.
b) Tuck the opposite side of the mask under one of the
damper’s grille mounting ears and push mask up into
damper housing.
Note: Mask can be put in place before or after the
blowers assembly is installed.
Remove mask before installing grille or operating
fan.
4. Attach the metal grille, supplied, over the inlet face of
the radiation damper using #8 (M4) sheet metal screws
(provided). There must be a minimum of one screw
on each of two opposite sides. For best results, use
mounting holes provided.
