□Duct work should be installed in a straight line with minimal
bends.
□Duct work size must be the same size as the discharge and
should not be reduced. Reducing the duct size may increase fan
noise.
□If this unit is to be installed over a tub or shower, it must be
marked as appropriate for the application. When the fan is
going to be installed in the bathroom, the fan and the tub must
be more than 1.0 meters between each other. The fan must be

applicable codes and standards, including re-rated
construction.
WARNING: Sufcient air is needed for proper combustion
and exhausting of gases through the ue (chimney) of
fuel 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); the American Society
for Heating, Refrigeration and Air Conditioning Engineers
(ASHRAE); and local code authorities.
WARNING: When cutting the ceiling, do not damage

Pre-Installation
TYPICAL INSTALLATION
The ducting from this fan to the outside of the building has a strong
effect on the air ow, 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 ow.
Do not install ventilation fan in areas where the duct work will
require conguration as shown.
Ensure duct joints and exterior penetrations are sealed with
caulk or other similar material to create an airtight path,
minimize building heat loss and gain, and reduce the potential for
condensation.
Place/wrap insulation around the duct and/or fan to in order to
minimize possible condensation buildup within the duct, and
building heat loss and gain. Wall cap
