WIRING
PLATE
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 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.
Short piece of flexible
duct helps alignment
and absorbs
sound

The fan will operate most efficiently when located
where the shortest possible duct run and minimum
number 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
