INSTALL VENT AT CLEARANCES SPECIFIED BY THE VENTING MANUFACTURER
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.
