PART 2 OPERATION 1 ) SEQUENCE OF OPERATION IMPORTANT The burner must be put in operation for at least 10 minutes before any test readings are taken . For new 1.1 ) Sequence of operation - Beckett AFG : installations , set up the burner to the settings ( see table # 3 ) , before firing . These are rough adjustments but 1 . Normally open contact ( T - T ) on primary relay closed when thermostat calls for heat . they will ensure that the burner will start and run smoke - free in advance of the fine adjustments being made . 2 . The motor starts and spark is established . The pump pressure builds and the poppet valve opens admitting fuel to the nozzle . Pressure builds and poppet valve opens , allowing oil to flow Open the oil bleed port screw and start the burner . Allow the oil to through nozzle . flush into a portable container for at least 10 seconds . Slowly close the bleed screw - the oil should flow absolutely free of white streaks or 3 .

The ignition transformer ceases sparking . disconnect switch and CALL YOUR SERVICEMAN 9 . Depend on the delay of setting of the fan control , the circulating air blower stop after 60 , 90 , ! 20 or 150 seconds . ( See part 2 , section 2.4 ) . CAUTION Do not attempt to start the burner when excess oil has 2 ) CHECKS AND ADJUSTMENTS accumulated , when the furnace is full of vapour , or when the combustion chamber is very hot . 2.1 ) General : 2.3 ) Perform the smoke / CO2 test : During initial start - up and subsequent yearly maintenance calls , the furnace must be thoroughly tested . 1 . Pierce a test hole in the smoke pipe near the furnace breech . Insert the smoke test instrument probe into the open hole . 2 . Starting with a zero smoke reading , gradually reduce the burner air setting until just a trace ( # 1 on Bacharach Scale ) of smoke results . 3 . Take a CO2 sample at the same test location where the smoke sample was taken . Note the CO2 reading associated with the # ! smoke condition . 4 . Adjust the burner air setting to obtain a CO2 reading ! % lower than the reading associated with the # 1 smoke . 5 . This method of adjusting the CO2 will allow adequate excess air to ensure that the burner will burn clean for the entire heating season .
