Combustion Air and Venting

SECTION II - Combustion Air and
Venting
Combustion Air Contamination
If the PRESTIGE Excellence combus-
tion air inlet is located in any area likely
to cause or contain contamination, or if
products, which would contaminate the
air cannot be removed, the combustion
air must be repiped and terminated to
another location. Contaminated com-
bustion air will damage the unit and its
burner system, resulting in possible
severe personal injury, death or substan-
tial property damage.
Do not operate a PRESTIGE Excellence
if its combustion air inlet is located near
a laundry room or pool facility. These
areas will always contain hazardous con-
taminants.
Pool and laundry products and common
household and hobby products often
contain fluorine or chlorine compounds.
When these chemicals pass through the
burner and vent system, they can form
strong acids. These acids can create cor-
rosion of the heat exchanger, burner
components and vent system, causing
serious damage and presenting a possi-
ble threat of flue gas spillage or water
leakage into the surrounding area.
Please read the information listed below.
If contaminating chemicals are located
near the area of the combustion air inlet,
the installer should pipe the combustion
air inlet to an outside area free of these
chemicals per SECTION V of this
installation manual.
