INSTALLATIONS
Proper insulation around the fan to minimize building heat loss and
gain. 4'' circular duct is recommended for installation. 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 air
flow.
