Installation of Ceiling Grille Housing With or Without Light
1. Plan Location of Inlet Grilles.
Based on the bathroom layout and fixtures, plan the location of the ceiling
grilles for the most effective ventilation.
2. Securing the Housing to the Ceiling Joists.
NEW CONSTRUCTION
Mount housing directly to the ceiling joist using screws and keyhole slots.
Locator tabs on housing should be flush with the bottom edge of the ceiling
joist for correct positioning of the unit once drywall is installed.
(Figure 1)
OR
Use the hanger bars to suspend the housing between ceiling joists. For
correct positioning, hanger bars should be positioned
bottom edge of the ceiling joist on models with 4" duct connection and
up from bottom edge of joist on models with 6" duct connection. On
models with 4" duct, tighten anti-slide screws to keep hanger bars in
place. (Figure 2).
Note: Hanger bars on units with 4" duct connection can be used on ceiling
joists up to 24" on center. Hanger bars on units with 6" duct connection
span ceiling joists up to 16" on center.
Note: If drywall or ceiling material is thicker than
be removed to allow the grille collar to be flush with the finished ceiling
material. When ceiling drywall is being installed, cut hole for ceiling grille.
EXISTING CONSTRUCTION OR WHEN DRYWALL IS IN PLACE.
Cut a 6" round hole for the ceiling grille only and install the housing from
the attic. (Figure 3)
Place the housing against the ceiling joist using the locator tabs to
determine the correct position (Figure 1) or align it using the hanger bars.
(Figure 2).
Punch out the keyhole knockouts (if using) and the electrical knockout if needed.
To complete installation for Bath Fan models with lights, continue with
steps 3 through 5. For models without lights, skip to steps 4 and 5.
3. Make Electrical Connections to the Ceiling Grille Housing.
Remove the electrical cover inside the steel housing using a screwdriver.
Connect power by following wiring diagram (Figure 5) and following local
or National Electrical Codes. Replace the electrical cover.
4. Connect the Fan to the Ceiling Grille Housing(s).
diameter duct from the fan to the ceiling grille housing. (Insulated flexible
duct is recommended for all Fantech bathroom exhaust applications for
quieter operation.) For dual grille models, install duct between fan and
wye adapter* (included). Then, attach duct to each leg of the wye and to
each ceiling grille housing. Secure duct in place and seal. If using insulated
flexible duct, seal the inner liner to the duct connector then seal the outer
shell over the top of the inner liner. Do not leave the insulation material
exposed.
5. Installing the Bulb.
Install the bulb by gently inserting it into the
socket in the grille housing. Install the grille by pushing it firmly into the
steel collar until it is shouldered by the ceiling drywall (Figure 3).
Repeat steps 1 through 5 for each additional ceiling grille housing being installed.
ADDITIONAL STEPS REQUIRED WHEN INSTALLING A FLUORESCENT
MODEL OVER A TUB OR SHOWER.
(Figure 4)
1. Place ring 1 on on socket legs first.
2. Screw metal shield in place over socket.
3. Add rubber gasket
4. Secure ring 2 to socket. Click indicates a secure installation.
* For most efficient operation wye adapter should be positioned the equivalent of
three duct diameters away from the fan inlet.
