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

the National Fire Protection Association (NFPA),and the American Society for
Heating, Refrigeration and Air Conditioning Engineers (ASHRAE),

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.
