member 120 is forced open permitting fuel to travel into the burner housing 102 where it passes through the openings 112 in the plate 104 and into the wick 110 if the fuel flow switch 138 remains open a fuel fault indicator light 152 is lit if the fuel flow switch 138 closes and the flame sensor 140 indicates no flame power is continued to the glow plug 122 due to the time delay 157 the time delay 157 allows for slow ignition with thick fuels without flooding when the burner ignites the flame sensor 140 detects the flame and the glow plug relay 154 is unlatched disengaging power to the glow plug 122 the microprocessor 131 then steps up the voltage across the fuel pump motor 32 and blower motor 38 increasing fuel and air delivery and holds them at a predetermined level the microprocessor senses and stores in memory the temperature indicated by the air temperature sensor 136 if a decrease is sensed fuel delivery is increased again by an increment if no decrease is sensed the microprocessor then incrementally increases and holds voltage across the blower motor 38 increasing the flow of forced air to the combustion chamber 44 the microprocessor 131 again checks for a temperature decrease from sensor 136 if the temperature decreases fuel supply is incrementally increased and held enriching the fuel air mixture temperature at sensor 136 will then go up the microprocessor again increases blower speed and senses for a temperature drop at 136 the cycle continues until maximum voltage is across the blower motor 38 once maximum blower speed has been achieved and air temperature increases as indicated by the sensor 136.
