B. Check/Adjust Electrodes
Check the electrode tip settings. Adjust if necessary
to comply with the dimensions shown in
Figure 3
. To
adjust, loosen the electrode clamp screw and slide/rotate
electrodes as necessary. Securely tighten the clamp
screw when
fi
nished.
Section: Nozzle Assembly Maintenance
Correct Nozzle and Flow
Rate Required
Incorrect nozzles and
fl
ow rates could
result in impaired combustion, under-
fi
ring, over-
fi
ring, sooting, puff-back of
hot gases, smoke and potential
fi
re or
asphyxiation hazards.
Use only nozzles having the brand,
fl
ow rate (gph), spray
angle and pattern speci
fi
ed by the appliance manufacturer.
Follow the appliance manufacturer’s speci
fi
cations for the
required pump outlet pressure for the nozzle, since this
affects the
fl
ow rate.
y
Nozzle manufacturers calibrate nozzle
fl
ow rates at
100 psig.
y
When pump pressures are higher than 100 psig, the
actual nozzle
fl
ow rate will be greater than the gph
stamped on the nozzle body. (Example: A 1.00 gph
nozzle at 140 psig = 1.18 gph)
Securely tighten the nozzle (90 torque inch pounds). For typical
nozzle
fl
ow rates at various pressures refer to
Table 2
.
Use care when removing or
installing an oil nozzle
A damaged nozzle could cause impaired combustion,
sooting, puffback of hot gases, oil leakage and
potential
fi
re or asphyxiation hazards.
y
Inspect the nozzle adapter to insure that the sealing
surface is not grooved or scratched.
y
To insure that the nozzle functions properly, check the
ori
fi
ce and strainer for dirt, scratches or other damage
before installation.
y
Do NOT attempt to install or remove a nozzle without
securing the adapter to prevent seriously damaging
the alignment.
y
Use care when handling the nozzle line assembly
to prevent changing the electrode tip settings or
damaging the ceramic electrode insulators.
y
Insure that the electrode setting match the values
shown in
Figure 3
.
Figure 2. Nozzle, Line & Electrode Assembly
3. If the nozzle is already installed, remove the nozzle
line assembly to verify that the nozzle size and spray
pattern are correct for the application (per equipment
manufacturer’s information). Verify that the electrode
tip settings comply with
Figure 3
.
