Vent Information
Do not terminate vent in any enclosed or semi-enclosed
area such as a carport, garage, attic, crawl space, under a
sun deck or porch, narrow walkway or closely fenced area,
or any location that can build up a concentration of fumes
such as a stairwell, covered breezeway, etc.

Vent Information
A. Venting Termination Requirements
Termination must exhaust above air inlet elevation. It is recom-
mended that at least 60 inches (1524mm) of vertical pipe be
installed when appliance is vented directly through a wall. This
will create a natural draft, which will help prevent the possibility of
smoke or odor venting into the home during a power outage. It will
also keep exhaust from causing a nuisance or hazard by exposing
people or shrubs to high temperatures. The safest and preferred
venting method is to extend the vent vertically through the roof.
