3.1 COMBUSTION AIR CONTAMINATION
WARNING!
If the Esteem boiler combustion air inlet is located in any area
likely to cause or contain contamination, or if products, which
would contaminate the air cannot be removed, the combustion air
must be re-piped and terminated to another location.
Contaminated combustion air will damage the unit and its burner
system, resulting in possible severe personal injury, death or
substantial property damage.
WARNING!
Do not operate the Esteem boiler if its combustion air inlet is
located near a laundry room or pool facility. 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 burner and vent system, they can
form strong acids. These acids can create corrosion of the heat exchanger, burner components
and vent system, causing serious damage and presenting a possible threat of flue gas spillage
or water leakage into the surrounding area.
Please read the information listed below. If contaminating chemicals are located near the area
of the combustion air inlet, the installer should pipe the combustion air inlet to an outside area
free of these chemicals per Chapter 5 of this installation manual.
