1. Plan installation so that ceiling penetration is located within ceiling tiles or pan-
els without necessitating cuts in any ceiling suspension main runners or cross
tees. If required, a maximum of one runner or cross tee may be cut to accom-
modate desired damper location. Cut ends must be supported by a minimum
12 steel wire gauge (3mm) vertical hanger wire.
2. 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. Use of a
plastic grille requires that a
minimum 5/8” (16mm) wide ceiling support flange of steel (not provided)
be attached to the radiation damper around the inlet face, using #8 (M4)
sheet metal screws or 1/4” (6mm) diameter bolts with nuts. There must be a
minimum of two connections on each of the four sides. Care must be taken to
ensure that the fasteners do not interfere with the closing of the damper cur-
tain.
3. Mount fan/damper assembly to the deck or ceiling structure above or adjacent
to the assembly. If the assembly is hung from the structure above, a minimum
12 steel wire gauge (3mm) hanger wire must be used. There must be a mini-
mum of two wires on each of two opposite sides. If the assembly is directly
mounted to the adjacent structure, use #8 (M4) sheet metal screws or 1/4”

(6mm) diameter bolts with nuts to mechanically fasten it to the structure. Posi-
tion fan/damper assembly so that the inlet face of the radiation damper is flush
with the finished surface of the ceiling. Ceiling opening must be no larger
than the inlet opening of the damper.
4. Attach the grille supplied with the fan 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.
