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.
The inlet to the intake must be below and a minimum of
12” (30cm) away from the unit exhaust outlet.
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 3” minimum (76 mm)
ID (inside diameter) steel, aluminum or copper pipe or
ducting 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.
