These should beconspicuously posted in the burner room at the time of theinitial burner installation and start up.Always turn the power supply off to the burner and closemanual fuel valves as appropriate for routine maintenance.Make sure that combustion and ventilation fresh air sourcesto the burner room remain clean and open.Periodically check all electrical connections and makesure the flame safeguard control chassis is firmly connectedto its wiring base.Refer to manufacturer s product bulletins supplied withthe burner for maintenance on the flame safeguardcontrol and other components.
