NOTICE:
Termination must exhaust above air inlet elevation.
• It is recommended that at least 60 inches (1.5m) 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.
