If the boiler combustion air inlet is located
in a laundry room or pool facility, for
example, these areas will always contain
hazardous 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 contaminants permanently.
—OR—
• Relocate air inlet and vent
terminations to other areas.

Table 1 Corrosive Contaminants and Sources
ƽ WARNING
If the boiler combustion air inlet is located
in any area likely to cause contamination,
or if products which would contaminate
the air cannot be removed, you must have
the combustion air and vent re-piped
and terminated to another location.
Contaminated combustion air will damage
the boiler, resulting in possible severe
personal injury, death, or substantial
property damage.
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 listed in Table 1. 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 Outdoor
Knight Boiler Installation and Operation Manual.
