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.

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

To install a new nozzle, place a 

3/4

” open-end 

wrench on the nozzle adapter. Insert the nozzle 
into the adapter and secure fi nger tight. Finish 
tightening with a 3/8” open-end wrench. Use care 
to avoid bending the burner head support legs or 
electrodes.

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.

Carefully check and realign the electrode tips af-
ter replacing a nozzle, ensuring the electrode set-
tings comply with Figure 6a or 6b.

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”.

  Check the electrode tip settings, as shown in Figure 

6a or 6b. If necessary, adjust by loosening the elec-
trode clamp screw and slide/rotate the electrodes 
as necessary. When the adjustment is complete, 
securely tighten the clamp screw.
