IMPORTANT: This unit must be connectect to an 80mm stainless steel vent pipe exhausting outside
the building.
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 305mm
(12”) 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 50mm minimum (2”) 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.
