Good Tuning: Yellow Flames, No Smoke
d.
IMPORTANT: The size of the flame may vary depending on oil temperature, especially
for yellow grease. From a cold startup, flame size may increase as the fuel is heated.
Adjust flame size with the Flame Control as temperature equilibrium is achieved.
e.
Air pressure should be between 10 and 40 pounds per square inch (psi). Adjust pressure
regulator on the Power Cabinet to achieve this value. If pressure falls below this range the
oil mist droplets get larger and combustion may be incomplete. Higher pressures are
capable of handling more visous oils. Maximum pressure is 100 psi.
f.
If you run the oil storage container to the lower levels, there is an increased chance of the
float encountering water or wet fuel. This may make the flame unreliable. Monitor all fuel
additions to minimize water additions. Strive to keep your fuel tank more than half full at
all times. Remove any accumulated water from the bottom drain periodically.
MAINTENANCE
a.
Yellow Heat Furnace:
Proper operation of the Yellow Heat Burner should require only
minimal maintenance on the Yellow Heat Furnace. If the observation window becomes
too obstructed to use, remove when flame is off and clean with a razor scraper, included
with each Yellow Heat Furnace. Annually, the burner should be removed from the front of
the furnace and any accumulated ashes should be removed with the supplied custom
trowel. The heat exchanger should be cleaned with compressed air annually for maximum
performance.
b.
Yellow Heat Burner:
Periodic maintenance is required for all liquid fuel burners and
more often for waste oil burners. Daily cleaning of the electrodes may be required with
dirty oils. Monthly and annual maintenance chores should be planned.
c.
Fire Tube:
The steel reducing elbow on the bottom of the Fire Tube may be removed
annually to eliminate any char build-up. Burners operating on dirty oil, such as from a
fryer operation that fries a lot of breaded product, will require more frequent maintenance
than from a cleaner oil source. The fire tube interior should be cleaned with a steel 4”
diameter flue brush. Remove burner tube from chassis at the rear and brush into firebox.
d.
Oil Heater:
Unplug heater element if burner is not being used seasonally or for an
extended period of time. Annual maintenance includes removing oil heater coverplate and
cleaning the oil channel of any adhered debris. Tighten coverplate evenly and completely
to compress gasket.
