The oil nozzle tip should be seated tightly in the body with the swirler and the seating spring in place. See Section
8.7 for additional nozzle tip information.
Check to see that the flame detector sight tube and the gas pilot tube extend through their respective openings in
the diffuser face.
6.23 — Oil Drawer Switch
The integral contacts of the control are closed by proper positioning and latching of the oil drawer in its forward
position. Adjustment of the switch must be such that its contacts open if the oil drawer is not properly positioned
for oil firing. The switch is electrically removed from the circuit when a combination fuel burner is fired on gas.
