burning equipment to prevent backdrafting. Follow the
heating equipment manufacturer's guideline and safety
standards such as those published by the National
Fire Protection Association (NFPA), and the American

PLAN THE INSTALLATION
Adequate ventilation requires that both intermittent and
continuous contamination be controlled.
Intermittent ventilation must be provided in the bath-
room and kitchen. The bathroom requires 8 air changes
per hour.
(Multiply bathroom sq. footage by 1.1 for proper fan sizing)
The kitchen requires a minimum of 150 CFM capacity
(71 l/s) when a ducted range hood is used. If a kitchen
fan is used, determine fan capacity by multiplying the
room's sq. footage by 2. All are run intermittently to control
pollution at the source.
Continuous ventilation, while the house is occupied,
provides the flow of fresh air for good indoor air quality.
This ventilator is intended to for continuous operation,
supplying fresh air to the entire house.
WARNING
5. When cutting or drilling into wall or ceiling, do not
damage electrical wiring and other hidden utilities.
6. Ducted fans must always be vented to the outdoors.
7. This unit must be grounded.
CAUTION
1. For general ventilating use only. Do not use to exhaust
hazardous or explosive materials and
vapors.
2. To avoid motor bearing damage and noisy and/or un-
balanced impellers, keep drywall spray, construction
dust, etc. off power unit.
3. If ventilator is installed in an unconditioned space
(such as an attic): Surround the ventilator with thermal
insulation - to minimize possible condensation.
4. Please read specification label on product for
further information and requirements.
