Boiler Cleaning
WARNING
All boiler cleaning must be completed with burner service switch turned off. Boilers equipped with burner
swing door have a potential hazard which can cause severe property damage, personal injury or loss of
life if ignored. Before opening swing door, turn off service switch to boiler to prevent accidental firing of
burner outside the combustion chamber. Be sure to tighten swing door fastener completely when service is
completed.
