Prevent combustion air contamination
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 pos-
sible severe personal injury, death or substantial property damage.
Do not operate an Ultra boiler if its combustion air inlet is located in a laundry room or pool facility, for
example. These areas will always contain hazardous contaminants.
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 below. 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.
