Babington Ball:
The Babington ball is a low maintenance item, but check the surface of
the ball every 100 hours of operation to see if there is any carbon buildup that might
interrupt or misdirect the flow of oil. If carbon buildup occurs, clean surface of the ball
with paper towels and a good solvent, such as biodiesel. Always maintain air pressure
(30+ psi) inside the Babington ball while cleaning its surface to keep the extremely small
exit hole from becoming clogged. The 2-year warranty on the operation of the Babington
ball burner head is void if this proceedure is not followed in every instance. A partially
clogged Babington ball may be restored by using a propane torch to heat the exit hole of
the ball while full air pressure is being applied through the ball.

Fuel Input Strainer:
The stainless steel strainer has a 60 mesh screen that protects the
pump from excessive solids. Clean screen by using spatula when liquid starts to back up.
Use paper towels on both surfaces to absorb any remaining oils that might polymerize if
left in place.
g.
Main Strainer
: The second in-line fuel strainer has a 60 mesh cleanable stainless steel
strainer. If this strainer clogs frequesntly, additional precleaning of the fuel is
recommended. Contact
Tom at Homestead Inc.
to discuss best alternatives. All fuel
strainers need annual cleaning in normal operation. The large diameter gasket should be
replaced to assure air tightness.
h.
Oil Pump
: The oil pump is not self-priming. The priming proceedure is to open the pump
bleed valve on the lower edge with a 3/8” open end wrench (included with each Yellow
Heat burner) a couple of turns. Add an oil container below this bleed valve. Turn on
pump, while in startup mode, press top control button on Controller to add one minue of
timing to the startup proceedure. Press top button multiple times to get up to 10 minutes of
startup time. Oil pump is fully primed when the bleeder oil stream is consistent without
any bubble interruptiuon for at least 30 seconds. When all bubbles are past, the oil pump is
fully bled and the bleed valve is to be closed.
There is a 160 mesh screen surrounding the pump mechanism under the cover. If this
screen becomes clogged it should be replaced and a new gasket installed. Tighten the four
cover bolts thoroughly.
i.
Electrodes:
Build-up of carbon residue on the electrode points or insulators can cause
ignition failure. Electrodes may need to be cleaned as often as daily, depending on the
suspended matter and consistency of your fuel. If the fuel stream is handled as
recommended by Homestead Inc., weekly maintenance of the electrodes is sufficient.
Turn off Power. Use a 7/16” wrench (as supplied with the Yellow Heat burner) to remove
compressed air inlet line. Remove finger-tight knurled ring. Open burner hinged cover
and remove Ignition Drawer. Loosen ceramic insulator clamp. Clean ceramic insulators
with paper towel until essentially white along their length. A B-100 cleaning solution is
appropriate for the ceramic. Emery cloth may be used to clean ceramic. Do not use steel
wool as it may encourage voltage leakage.
The metal electrodes should be cleaned with emery cloth as required to achieve bare
