The oil nozzle tip should be seated tightly in the body with the swirler and the seating spring in place. See Section

the diffuser face.

The integral contacts of the control are closed by proper positioning and latching of the oil drawer in its forward

for oil firing. The switch is electrically removed from the circuit when a combination fuel burner is fired on gas.
