Combustion Air Contamination

WARNING
If the PERFORMANCE combustion 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 an outside
location. Contaminated combustion air
will damage the unit and its burner sys-
tem, resulting in possible severe personal
injury, death or substantial property
damage.
WARNING
Do not operate a PERFORMANCE if its
combustion air inlet is taken inside in a
laundry room or pool facility.
areas will always contain hazardous con-
taminants.
Pool chemicals, laundry products, com-
mon household cleaners and hobby
products often contain fluorine or chlo-
rine compounds. When these chemicals
pass through the burner and vent sys-
tem, they can form strong acids. These
acids can create corrosion of the outer
tank, burner components and vent sys-
tem, causing serious damage and pre-
senting a possible threat of flue gas
spillage or water leakage into the sur-
rounding area.
Please read the information listed below.
If contaminating chemicals are located
near the location of the combustion air
inlet, the installer should pipe the com-
bustion air inlet to an outside area per
