Outside fresh air is mandatory when installing this
unit in airtight homes and mobile homes.
When connecting to an outside fresh air source, do not use
plastic or combustible pipe. A 1” minimum (42 mm) ID
(inside diameter) steel, aluminum or copper pipe should be
used. It is recommended, when you are installing a fresh
air system, to keep the number of bends in the pipe to a
minimum.
