RU80i, RU98i
The vent for this appliance shall not terminate

Over public walkways; or

Near soffit vents or crawl space vents or other
area where condensate or vapor could create a
nuisance or hazard or cause property damage; or

Where condensate or vapor could cause damage
or could be detrimental to the operation of

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 intake part of the termination.
