Cleaning sludge and water from the bottom of the tank:
NOTICE:
Because of the nature of used oil handling practices, it is very difficult to keep all water
and sludge out of the used oil supply. Drain the used oil supply tank at least once a year to ensure no
unwanted substance is being delivered to the boiler.
(1) Connect a tube to the drain on the bottom of the tank and collect a sampling in a drain pan
or bucket. Keep draining the tank until all water and sludge has been removed.
(2) If there is no drain on your supply tank insert a transfer pump with the suction line inserted
down to the bottom of the tank. Keep pumping out the tank until all sludge and water has
been removed.
MAINTENANCE
CAUTION:
Wear safety goggles, gloves, long sleeves and a dust mask when
cleaning ash form the boiler. The accumulated ash is in the form of a fine powder and
may cause irritation.
CAUTION:
DO NOT attempt to clean ash from a hot boiler. It is a burn hazard as well
as a fire hazard when the hot ashes are disposed of.
