Motor Lubrication:
Oil motor with one or two drops of non-detergent motor oil.
Priming The Fuel Units: Locate the air bleed valve on the fuel unit (pump).
Place a container underneath the air bleed valve. Open the air bleed valve by
turning it one quarter of a turn in the counter-clockwise direction. Turn the
thermostat on the water heater to a setting that is high enough to allow the burner
to operate. Turn on the power supply to the burner. After the air is pumped out of
the fuel unit, let at least one pint of oil flow into the container. While running under
these conditions, the pressure valve in the pump will not open; hence, there will be
no flame. When a pint of oil has flowed into the container, close the air bleed
valve. The burner should start burning when the air bleed valve is closed.
The above is not necessary when a two-pipe system is used. Install the pressure
gauge and turn burner on. The system will vent itself through the return line and
flame will appear as soon as the air has been eliminated. In the event a lot of air is
present and flame is not sighted within 45 seconds, the cad cell will cause the
relay to cut off for protection. It may then be necessary to push the reset button on
the burner on the burner module.
WARNING
Escaping flue gases can be lethal. Make sure that the flue and venting
system is checked at least once a year by a plumbing professional or
the oil supplier's service technicians.
