INSPECTIONPROCEDURES
BURNERS
Clean main burners and air louvers of dust, lint and debris. Keep boiler area clear and free from com- bustibles and flammable liquids. Do not obstruct the flow of combustion and ventilating air. Make visual check of burner and pilot flame. Yellow flame indicates clogging of air openings. Lifting or blowing flame indicates high gas pressure. Low flame indicates low gas pressure.
