NOTICE:
Do NOT Terminate Vent:
• In any location that will allow fl ue gases or soot from en-
tering or staining the building
• In any location which could create a nuisance or hazard
• In any enclosed or semi-enclosed area such as a carport,
garage, attic, crawl space, under a sun deck or porch,
narrow walkway
• Closely fenced area, or any location that can build up
a concentration of fumes such as a stairwell, covered
breezeway, etc.
NOTICE:
Termination must exhaust above air inlet elevation.
• It is recommended that at least 60 inches (1.52m) of ver-
tical 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.
