Air contamination
Pool and laundry products and common household and hobby
products often contain fl uorine or chlorine compounds. When
these chemicals pass through the boiler, they can form strong
acids. The acid can eat through the boiler wall, causing serious
damage and presenting a possible threat of fl ue gas spillage or
boiler water leakage into the building.
Please read the information given in Table 1A, page 11,
listing contaminants and areas likely to contain them. If
contaminating chemicals will be present near the location of
the boiler combustion air inlet, have your installer pipe the
boiler combustion air and vent to another location, per this
manual.
