INSTALLATION INSTRUCTIONS

WARNING: TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK,

OR INJURY TO PERSONS, OBSERVE THE FOLLOWING:

A. 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 and be connected to a GFCI (Ground Fault Circuit Interrupter)

protected branch circuit.
F. NEVER place a switch where it can be reached from a tub or shower.

• Do not install in a ceiling insulated to a value greater than R40.

• Suitable for use with solid state speed controls. Use NuTone Model VS-64.

FOR BEST RESULTS

When installing the Ventilator in a new construction site, install housing during

the rough-in construction of the building. The blower unit and grille should be installed
after the finished ceiling is in place.

To install a ventilator in an existing building requires an accessible area (attic or

crawl space) above the planned location.

with installation. Refer to Figure 2 for wiring and Figure 1 for
ducting. CAUTION: Check area above planned installation to
be sure that the ducting can be installed, wiring can be run to
the planned location and that wiring or other obstructions will
not interfere with the installation.

INSTALLATION FROM ACCESSIBLE AREA
ABOVE

1. From below, drill a small hole in ceiling at the planned location.
Stick clothes hanger through hole to help locate it.

2. Locate hole in attic or crawl space.

3. In attic or crawl space, mark ceiling for cutout by using the
housing as a template. The long side of cutout must be parallel
