Do not operate the Combi Boiler if its combustion air intake is located in or near one of the areas or in the vicinity of products listed in
Table. These areas will always contain hazardous contaminates that can form strong acids while passing through the burner and vent
system. These acids will corrode the Combi Boiler’s heat exchanger, burner components and vent system, resulting in ue gas spillage
and/or water leakage, possible substantial property damage, severe personal injury, or death. If the Combi Boiler combustion air intake
is located in any area likely to cause or contain contamination, or if products which would contaminate the air cannot be removed, the
intake must be re-piped and terminated to another location.
