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.
