5. Sufficient air is needed for proper combustion and exhausting of
gases through the flue (chimney) of fuel burning equipment to
prevent excessive low pressure and to prevent back drafting. Follow
the heating equipment to guidelines 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.
6. When cutting or drilling into wall or ceiling, do not damage
electrical wiring and other hidden utilities.
7. The wiring must be permanent. DO NOT USE EXTENSION CORD!
Although the Powered Gable Ventilator may be wired directly to
power, we advise that some type of shut off switch be installed on
the line. Please see the section on electrical wiring for suggested
wiring diagrams and instructions.
8. For general ventilating use only. Do not use this fan to exhaust
hazardous or explosive materials or vapors.
9. To avoid motor bearing damage and noisy and/or unbalanced
impellers, keep drywall spray, construction dust, etc. off power unit.
10. Ensure that the power source conforms to the electrical
requirements of the fan.
11. Always disconnect power before inspection or cleaning, as motor
may restart unexpectedly.
12. In cases in which property damage may result from malfunction of
the fan, a suitable alarm (air switch, temperature sensor, etc.)
should be used.
