User’s Information Manual
Part number 550-100-181/0517
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.
Do not operate an SlimFit 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 com-
pounds. 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.
