To ensure quiet operation of ENERGY STAR qualified inline fans, each fan shall be installed using sound attenuation techniques appropriate
for the installation. Insulated flexible type duct work (recommended for all bathroom exhaust applications) will result in quieter operation.
We recommend minimum 8” of insulated flexible duct between any exhaust grill and fan for low noise level. Flexible duct should be
connected to the fan with hose clamps (VENTS C series is recommended), aluminum foil tape or both. All connections should be as
airtight as possible to maximize system performance and eliminate air leakage. When using flexible type duct work, duct should as tight
and straight as possible. In case you intend to use non-flexible ducts we recommend to install flexible connectors (VENTS VVG series is
highly recommended) which are designed to exclude the vibration transmission from fans to air duct. Remove any insulation from the
area where you will be mounting the fan. Insulation should never be installed over any part of an exhaust fan. Keep the insulation at least
3” away from the fan case.
