Installation work and electrical wiring must be done by qualified person(s) in accordance with all applicable codes and standards, including fire-rated construction.B. Sufficient air is needed for proper combustion and exhausting of gases through the flue (chimney) of fuel burning equipment to prevent back drafting. Follow the heating equipment manufacturer’s guideline and safety standards such as those published by the National Fire Protection Association (NFPA), and the American Society for Heating, Refrigeration and Air Conditioning Engineers (ASHRAE), and the local code authorities.C. When cutting or drilling into wall or ceiling, do not damage electrical wiring and other hidden utilities.D. Ducted fans must always be vented to the outdoors.E. If this unit is to be installed over a tub or shower, it must be marked as appropriate for the application.F. NEVER place a switch where it can be reached from a tub or shower. For installation in sloped ceilings up to 12/12 pitch. Ductwork must point up.

When installing the Exhaust Fan/Light in a new construction site, install housing during the rough-in construction of the building. The blower unit, reflector and grille should be installed after the finished ceiling is in place. Refer to instructions on page 3 to install the Exhaust Fan/Light in an exist- ing finished building.

PLANNING DUCTWORK AND WIRING

1. Use 4” round duct.2. Plan duct run from discharge opening of fan to the outside. For best fan performance, make duct run as short as possible and use minimum num-ber of elbows.3. Use optional NuTone ducting accessories as needed.

MODEL: 8663RP, 8664RP

Suitable for use in shower or tub enclosure when used with GFI protected branch circuit. IMPORTANT: Use wire suitable for 90°C. Plan to run 120vAC house wiring (with ground) from power source, through wall switches, to junction box in fan. For separate control of fan, light, and night light three wall switches are required. See NuTone Catalog for accesso- ry switches. For separate control of fan, light, and night light, five conductors are needed between the wall switch box and the fan’s junction box. (Night light not provided on 8664RP).

MOUNTING THE HOUSING

Note: When installing in existing construction, refer to page 3 Mounting Using Mounting Tabs Refer to Figure 2.

1. Locate fan housing next to ceiling joist.

2. Use wood screws (not provided) to loosely attach housing to ceiling joist

through keyhole slots in mounting tabs.

3. Adjust housing so that it will be flush with finished ceiling. For the grille to fit

properly, the housing’s rim must not extend beyond finished ceiling surface.

4. When housing is properly adjusted, tighten screws in slots.

Mounting Using Hanger Bars Refer to Figure 3.

1. Insert hanger bars in slots provded in housing.

2. Locate fan housing between joists so that the bottom of the housing is even

with the planned finished ceiling.

3. Use screws or nails (not provided) to secure hanger bars to ceiling joists.

1. Refer to Figure 1. Place duct collar over flanges at discharge opening of fan.

Secure collar by snapping tabs into slots in flanges.

2. Run 4” round duct from fan’s discharge opening to the outside and terminate.

WIRING All wiring must comply with local codes and unit must be properly ground- ed. IMPORTANT: Use wire suitable for 90°C.

1. Run 120vAC house wiring from wall switches to fan location, neutral (white),

ground (bare copper), and three switched hot leads. See Figure 4.

2. Insert and secure an approved box connector into wiring entrance hole.

3. Pull wires through box connector and into junction box. Tighten box connector.

4. Refer to Figure 4A. (For 8663RP)

Connect white wires from the fan and light receptacles to white (neutral) wire from the supply. Connect black wire to wire from fan switch. Connect red wire to wire from light switch. Connect yellow wire to wire from night light switch. Refer to Figure 4B. (For 8664RP) Connect white wires from the fan and light receptacles to white (neutral) wire from the supply. Connect black wire from fan (BLK) receptacle to wire from fan switch. Connect blue from light (WH) receptacles to wire from light switch.

5. Connect the green (or bare) ground wire to the green ground lead.

FIGURE 2 Duct Collar Flanges Wiring Knockouts Mounting Tabs Bottom RimPOWER/BLOWER UNIT INSTALLATION

1. Refer to Figure 1. Place power/blower unit into housing so that mounting

INSTALLATION IN EXISTING CONSTRUCTION

Locate fan between ceiling joists. Plan ducting wiring before proceeding with installation. Refer to Figure 4 for wiring. CAUTION: Check area above planned location to be sure that:

1. Ducting can be installed.

2. Wiring can be run to the planned location.

3. No wiring or other obstruction might interfere with installation.

INSTALLATION FROM ACCESSIBLE AREA ABOVE

1. After determining desired location for fan, drill a small hole in the ceiling.

Place a coat hanger or other stiff wire up through hole to help in locating from above.

2. Place fan housing on top of ceiling surface and use the housing as a

template to mark area to be cut out. Cut round hole 13

⁄8” in diameter for rough opening.

3. After cutting out opening, mount housing in the opening using the hanger

bars provided. A. Insert hanger bars in slots in housing. B. Position housing in opening so that bottom of housing is flush with ceiling. C. Use screws or nails (not provided) to secure hanger bars to ceiling joists.

4. Install ducting and wiring as described above.

INSTALLATION FROM AREA BELOW CEILING

Note: If you do not have access to the area above the installation location, make sure that the installation will not interfere with existing wiring, plumbing, etc. and that the wiring and ducting can be run to the desired location. It will be neces- sary to use flexible duct when installing the unit from below.

1. The fan must be mounted between ceiling joists. Decide where you want to

locate the fan, and then determine where the nearest joists are. Locating Joists – Lightly tap the ceiling. A hollow sound means no joist; a solid sound means a joist is present. To be sure you have located a joist, drill a small hole (1/16”) and probe into the ceiling with a wire.

2. Locate the joists. Drill a starter hole in the ceiling between the joists.

3. To exactly locate the edge of joist, saw a line from hole to joist.

4. Refer to page 1. Remove power/blower unit from housing.

5. Use the housing pan as a template to mark cutout: place pan centered

between joist and trace around pan.

6. Make cutout along outside of marked line.

7. Refer to Figure 5. Install 2 x 4 cleats to both ceiling joists. In some cases it

may be necessary to use more than a single cleat on one side. The distance between cleats must be at least 9

⁄8” but not more than 10”.

8. Remove side wiring knockout and insert and secure an approved box con-

nector into the wiring entrance hole.

9. Use pliers to bend both mounting tabs as flush as possible to the side of the

11. String wiring through box connector and connect 4” flexible duct to duct col-

12. Carefully push ductwork and wiring back into cutout. Place housing into

13. Use wood screws to secure housing to cleats through four holes in hous-

ing’s pan. Make sure pan is flush to finished ceiling.

CLEANING AND RELAMPING

1. Pull grille assembly away from ceiling.

2. Squeezing the grille assembly’s mounting springs together, remove grille

assembly from housing to expose socket for relamping.

3. Clean grille and lens assembly using a mild soap and water solution.

Assemblies with wood frames should not be immersed.

4. Replace grille assembly flat against ceiling after cleaning or relamping.
