Nozzle Installation

!CAUTION Protect Nozzle from Damage

A damaged nozzle could cause impaired com- bustion, sooting, puffback of hot gases, smoke, oil leakage and potential fire or asphyxiation hazards.

Use care when handling, removing and installing oil nozzles.

Carefully follow the guidelines provided in this sec- tion.

Perform the following steps when replacing a nozzle.

1.Remove the nozzle line assembly to gain access to the nozzle.

2.Use a 3/4” open-end wrench to hold the nozzle adapter. DO NOT attempt to remove or replace the nozzle without securing the adapter, as noz- zle alignment could be seriously affected.

3.Do not squeeze the electrodes when handling the nozzle line assembly. Excessive force could change the electrode tip settings or damage the ceramic electrode insulators.

4.Use a 5/8” open-end wrench to carefully remove the existing nozzle.

5.Inspect the nozzle adapter before installing the new nozzle. If it is grooved or scratched on the sealing surface, replace the nozzle line assem- bly. If the surface is damaged, oil could leak at the nozzle to adapter joint, causing serious com- bustion problems.

6.Protect the nozzle orifice and strainer when in- stalling. If the orifice gets dirt in it or is scratched, the nozzle will not function properly.

7.To install a new nozzle, place a 3/4” open-end wrench on the nozzle adapter. Insert the nozzle into the adapter and secure finger tight. Finish tightening with a 5/8” open-end wrench. Use care to avoid bending the burner head support legs or electrodes.

8.Do not over-torque the nozzle when install- ing. This will cause deep grooves in the nozzle adapter, preventing a seal when a new nozzle is installed.

9.Carefully check and realign the electrode tips af- ter replacing a nozzle, ensuring the electrode set- tings comply with Figure 7.

10.If the head was removed when replacing the noz- zle, carefully reconnect the head to the nozzle adapter. Make sure to align the key in the support leg with the keyway in the nozzle adapter and to butt the head support to the nozzle adapter shoulder, see Figure 8.

• Check/Adjust Electrodes

Check the electrode tip settings, as shown in Fig- ure 7. If necessary, adjust by loosening the elec- trode clamp screw (Figure 8) and slide/rotate the electrodes as necessary. When the adjustment is complete, securely tighten the clamp screw.

Note that if the throttle cup is moved be sure to re- position it with no gap between the nozzle adapter and hub.
