SECTION II- Combustion Air and
Venting
Combustion Air Contamination
If the CHALLENGER combustion air
inlet is located in any area likely to cause
or contain contamination, or if products,
which could contaminate the air cannot
be removed, the combustion air must be
repiped and terminated to another loca-
tion. Contaminated combustion air will
damage the appliance and its burner sys-
tem, resulting in possible severe personal
injury, death or substantial property
damage.
Do not operate a CHALLENGER if the
combustion air inlet is located near a
laundry room or pool facility. These
areas will always contain hazardous con-
taminants.
Pool, laundry products, common house-
hold 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 corrosion
of the heat exchanger, burner compo-
nents 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 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 area free of these chemi-
cals per SECTION VI of this installation
manual.
