Vent Information
A.  Venting Termination Minimum Requirements
NOTICE:
Termination must exhaust above air inlet elevation.  
•  It is recommended 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 or above the roof.
