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

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.

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 this ventilator in an existing building requires an accessible area (attic or

crawl space) above the planned location.
