NOTICE:

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.

•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 (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.

*NOTE: Consult local building, fi re offi cials or authorities having jurisdic-	• The safest and preferred venting method is to extend the
