wiring can run to the planned location and that duct
work can be run. Make sure the area is sufficient for
proper ventilation.
Inspect duct work and wiring before proceeding with
installation.

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 duilding 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.
The fan will operate most efficiently when located
where the shortest possible duct run and minimum
of elbows will be needed.
Use a roof cap or wall cap that has a built-in damper
to reduce backdrafts.
External timer can be used please contact Delta
Breez customer service and consult with a licensed
electrician for compatibility.
