Combustion Air Contamination
If the PERFORMANCE PLUS 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 an
outside location. Contaminated combus-
tion air will damage the unit and its
b u r n e r system, resulting in possible
severe personal injury, death or substan-
tial property damage.
Do not operate a PERFORMANCE
PLUS if its combustion air inlet is taken
inside in a laundry room or pool facility.
These areas will always contain haz-
ardous contaminants.
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
SECTION VI of this installation manual.
