OUTSIDE FRESH AIR CONNECTION
Outside fresh air is mandatory when installing this unit in airtight
homes and mobile homes.
A Fresh-air intake is strongly recommended for all installations.
Failure to install intake air may result in improper combustion as well as
the unit smoking during power failures.
When connecting to an outside fresh air source, do not use plastic or
combustible pipe. A 2" minimum (51mm) 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.
