appliances are recommended for use in dust laden and some corrosive fume environments or
in buildings with negative pressure (up to .15" w.c.). As the definition states, all separated
combustion, power-vented equipment must be equipped with both combustion air and ex-
haust piping to the outdoors.
These units must be installed in accordance with local building codes. In the absence of local
codes, in the United States, the unit must be installed in accordance with the National Fuel
