SECTION I - COMBUSTION AIR - PREVENTION OF
CONTAMINATION
If the CHALLENGER combustion air inlet is located
in any area likely to cause or contain contamination,
or if products, which would contaminate the air can-
not be removed, the combustion air must be re-
piped and terminated to another location.
Contaminated combustion air will damage the appli-
ance and its burner system, resulting in possible
severe personal injury, death or substantial property
damage.
Do not operate a CHALLENGER if its combustion air
inlet or the appliance is located in or near a laundry
room or pool facility. These areas will always con-
tain hazardous contaminates.
Pool and laundry products and common household
and hobby products often contain fluorine or chlo-
rine compounds. When these chemicals pass
through the burner and vent system, they can form
strong acids. These acids can create corrosion of
the heat exchanger, burner components and vent
system, causing serious damage and presenting a
possible threat of flue gas spillage or water leakage
into the surrounding area.
Please read the following information. If contami-
nating chemicals will be present near the location of
the combustion air inlet, the installer should pipe the
combustion air inlet to another location per the
CHALLENGER installation manual.
