Connecting the Duct
● Install a circular duct to outlet and secure it with duct tape or clamps.
● Install the duct to the outlet with a gradient 1°~2° to the outside as shown.
● The ducting from this FAN to the outside of the building has a strong effect on
●
the air flow, noise and energy use of the fan. Use the shortest, straightest duct
●
routing possible for best performance, and avoid installing the FAN with smaller
●
ducts than recommended. Insulation around the ducts can reduce energy loss
●
and inhibit mold growth. Fans installed with existing ducts may not achieve their
●
rated airflow.
● 4 in (10.16 cm) round is recommended for best performance.
● Ensure duct joints and exterior penetrations are sealed with caulk or other
●
similar material to create an air-tight path, to minimize building heat loss and
●
gain, and to reduce the potential for condensation.
● Place/wrap insulation around duct and/or FAN in order to minimize possible
●
condensation buildup within the duct, building heat loss and gain.
