Important considerations for locating vent
termination under a soffit (ventilated or
unventilated or eave vent; or to a deck or porch):

DO NOT install vent termination under a soffit vent
such that exhaust can enter the soffit vent

Install vent termination such that exhaust and
rising moisture will not collect under eaves.
Discoloration to the exterior of the building could
occur if installed too close.

DO NOT install the vent termination too close
under the soffit where it could present recirculation
of exhaust gases back into the combustion air in-
take part of the termination.
