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 (51 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.
