Prevent combustion air contamination

If theboiler combustionair inletislocatedin anyarealikelytocause contamination,or if productswhich

wouldcontaminatethe aircannotbe removed,youmust havethecombustionair andventre-piped and

terminated to another location. Contaminated combustion air will damage the boiler, resulting in pos-

Do notoperate anUltra boilerif its combustionair inletis locatedin alaundryroomor pool facility,for

example.These areas will always contain hazardous contaminants.

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.
