Table 1 Corrosive contaminants

To prevent the potential of severe personal injury or
death, check for areas and products listed in Table 1
before installing the boiler or air inlet piping.
If contaminants are found, you MUST:
• Remove products permanently. — OR —
• Relocate air inlet and vent terminations to other areas.
Air contamination
Pool and laundry products and common household
and hobby products often contain fluorine 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 flue gas spillage or boiler
water leakage into the building.
Please read the information given in Table 1, 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 the Boiler Manual and Vent
Supplement.
If the boiler combustion air inlet is located in any area
likely to cause air contamination, or if products which
would contaminate the air cannot be removed, you
must have the combustion air and vent repiped and
terminated to another location. Contaminated
combustion air will damage the boiler heat exchanger,
resulting in possible severe personal injury, death or
substantial property damage.
Do not operate an Ultra boiler if the boiler combustion
air inlet is located in a laundry room or pool facility,
for example. These areas will always contain hazardous
contaminants.
