4.5.2 Termination
Considerations
Check to determine whether local codes
supersede the following 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 above 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
vented soffit that may result in exhaust
gases entering 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 cause
recirculation of exhaust gases back into
the combustion air intake portion of the
termination.
