AREAS WILL ALWAYS CONTAIN HAZARDOUS
CONTAMINANTS
.
Pool and laundry products and common house-
hold and hobby products often contain fluorine
or chlorine compounds. When these chemi-
cals 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 sur-
rounding 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 out-
side area free of these chemicals per Chapter
5 of this installation manual.
Potential contaminating products
• Spray cans containing chloro/fl uorocar-
bons

wax

• Sodium Chloride for water softening
• Refrigerant
leaks
• Paint or varnish removers
• Hydrochloric acid / muriatic acid
