FOR YOUR SAFETY:

 This product must be installed and serviced by a professional service technician, 

qualified in hot water boiler installation and maintenance. Improper installation and/or operation could 

create carbon monoxide gas in flue gases which could cause serious injury, property damage, or death. 

Improper installation and/or operation will void the warranty. For indoor installations, as an additional 

measure of safety, Bradford White strongly recommends installation of suitable Carbon Monoxide 

detectors in the vicinity of this appliance and in any adjacent occupied spaces.
