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 3/4open-end wrench on the nozzle adapter. Insert the nozzle into the adapter and secure finger tight. Finish tightening with a 3/8” 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 6a or 6b.

10.If the head was removed when replacing the nozzle, carefully reconnect the head to the noz- zle adapter. Push the head support until it stops against the nozzle shoulder. Verify the dimen- sion between the nozzle face and the back of the head is 5/32”.
