Installation Guide

1. Position the ceiling radiation damper on the inlet side of the fan such that the holes in the
damper mounting flanges line up with the holes in the flange of the fan housing. Secure the
damper to the fan housing using the four #10-32 machine screws/nuts supplied.
2A. For a damper used with a fan requiring a plug connector to pass through the damper, secure
the plug connector using the wiring bracket and #8 course threaded screw supplied. (See Figure
2A) If the plug connector cannot reach through the damper to the
grill plug attachments, release the clips holding the wiring inside the
fan with a Phillips-Head screwdriver. make sure the wire lead or
plug connector does not interfere with the closing of the damper.
2B. For a damper used with a fan that does not require a plug
connector, secure the wiring bracket supplied to the damper frame
using the supplied #8 course threaded screw supplied. Make sure the wiring bracket covers the
notch in the frame. (See Figure 2B).
3. With the damper secured to the fan housing, the assembly can be attached to the structure
above using the holes in the fan housing flange or the supplied mounting brackets.  If the
mounting brackets are used, position the mounting brackets under the damper mounting flanges
or under the fan housing flange as required. Position the slot so it aligns with the holes in the fan housing and/or the holes in
the damper mounting flanges (See Figure 3). If the damper/fan is being attached to the adjacent structure, the brackets must
be used and adjusted to fit accordingly. If the damper/fan is supported from structure above, the brackets should be adjusted
so the ends of the brackets align accordingly. Once the brackets are adjusted, attach them to the
flange of the fan housing using four #10-32 screws and nuts supplied. A minimum of two
fasteners per side is required.
4. The ceiling penetration should be located within ceiling tiles or panels without necessitating
cuts in the ceiling suspension main runners or cross tees. If required, a maximum of one runner
or cross tee may be cut to enable proper damper location and installation. Each cut end shall be
supported by a min. 12 swg (2.7) vertical hanger wire. The opening in the ceiling should be the
same size as the outside of the damper frame.
5. Position the damper/fan assembly such that the bottom edge of the damper is flush with the
finished surface of the ceiling. Attach the damper/fan assembly to the structure above or adjacent
to it. If the damper/fan is being attached to the assembly above, a minimum of 12 swg. (2.7)
hanger wire must be used. A minimum of two hanger wires on two opposite sides are required. The hanger wires can be
attached directly to the fan housing flange or to the ends of the mounting brackets. If the damper/fan assembly is being
directly mounted to the adjacent structure, a minimum #8 (M4) sheet metal screws or 1/2" dia. bolts/nuts must be used. If
necessary, a min. 1/2" wide flange is to be attached to the damper using a minimum #8 (M4) sheet metal screw, 3/16" pop
rivets, welds or bolts at 6" (152) o.c. maximum. A minimum of 2 connections per side is required.
