Additional clearances

Check on whether local codes supersede these clearances.
Avoid termination locations near a dryer vent.
Avoid termination locations near commercial
cooking exhaust.
You must install a vent termination at least 12
inches from the ground.
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.
