Installing Mounting Bracket & Fan
1. When selecting fan mounting location, the fol-
lowing criteria should be considered: a) mount-
ing to minimize noise generated by fan opera-
tion; b) service accessibility
a) Mounting the fan as far as possible from
the intake point will minimize fan operating
noise from being transmitted back
through the duct work. If the fan is to be
used as a booster for moving the air
between two rooms, a central point along
the duct may be optimal. Insulated flexible
type duct work (recommended for all
bathroom exhaust applications) will result
in much quieter operation. Fantech rec-
ommends minimum 8' of insulated flexible
duct between any exhaust grill and fan for
low noise level.
b) Fan location should allow sufficient access
for service.
2. Using the wood screws provided, attach the
mounting bracket (NB or MB) to a support beam
at the selected location. Fan mounting can be at
any point along the duct and in any angle, however, vertical mounting is recom-
mended to reduce condensation buildup in the fan. If a horizontal installation is
necessary and condensation buildup may pose a problem, either wrap insulation
Installing DG Supply/Exhaust Grill
If a Vent/Light combination kit is purchased, the VLC vent/lights are supplied with
a separate installation instruction replacing steps 1 through 4.
1. Select the grill mounting point within the area
to be ventilated. To ease installation, locations
of framing beams within the walls or joists sup-
porting the ceiling should be considered.
Collar/damper is provided with a perforated
hanging strap for attachment directly to a
beam or joist. Allow sufficient space between
the collar/damper and the beam to attach the
duct work. If the location of the grill does not
allow direct attachment, a cross-member
mounted to the framing should be used.
2. Place the mounting collar/damper in the select-
ed location and trace a circle onto the surface.
From the interior side of the room, cut through
the surface. Please note: In order to assure a
smoother finish when mounting through a sheet-
rock or tile type ceiling, it is recommended that
a razor knife be used to make the cut.
3. From within the attic or crawl space, place the
mounting collar into the hole until the edge of
the collar is flush with the interior wall or ceil-
ing surface. Attach collar to the support beam
with the 2" wood screws provided. Attach duct
work. Secure using CB or FC clamps and/or duct tape. When installing the
damper into rigid type ducting, FC clamps or duct tape should be used.
PLEASE NOTE: When attaching flex duct to the collar/damper combination and
an immediate elbow is necessary, be certain that the elbow is installed with
a "soft" bend to allow damper blades to operate properly.
4. Snap the grill into the mounting collar/damper. Grill should be pushed tightly
into place for an airtight fit. If there is a gap between the collar and the ceil-
ing it should be caulked to avoid air leakage. For subsequent cleaning the grill
can be pulled out and cleaned.

3. Attach fan to the mounting bracket with the
sheet metal screws provided. Wiring box should
be positioned for easy access. Bracket is pro-

4. Connect duct work to inlet and outlet of fan
using CB clamps or duct tape. When using
insulated duct, it is recommended that the inner
vinyl core be clamped or taped to the inlet and
outlet and that the vapor barrier surrounding
the insulation be duct taped to the fan housing.

Installing DG Supply/Exhaust Grill
When installing a DLX kit, a balancing damper has been included to allow for
adjustment of the system. The damper may be used where the grills will be con-
nected using branches of unequal length or where
the flow will need to be balanced for any reason.
To Install The Damper:
1. The Damper must be installed on the branch with
the least restriction.
This is generally the duct that is shortest or has
the fewest bends.
2. Drill a
edge on the flat side of the "Y".

3. Place the washer over the threaded shaft on
the damper.
4. Insert the damper, shaft first, into the hole just
drilled.
5. Attach the handle using the wing nut.
6. Adjust the damper to balance airflow and
tighten the wing nut to secure.
Flexible Duct Installation Hints
Flexible insulated duct is strongly recommended

where allowed by local code for bathroom exhaust
applications, where ducting passes through uncon-
ditioned space or where noise is a factor. Failure to use insulation could result in
excessive condensation buildup within the duct, and undesirable sound levels
within the room. For the quietest possible installations, Fantech recommends a
minimum of 8' of insulated flexduct between any exhaust grill and fan. When using
flexible type duct work, duct should be stretched as tight and straight as possible.
Failure to do so could result in dramatic loss of system performance. Flexible duct
should be connected to the fan with CB type clamps or duct tape. All connections
should be as airtight as possible to maximize system performance.
