OIL BOILER / BURNER CLEANING INSTRUCTIONS
OIL BOILER CLEANING;
4.
5.
1. Shut off all electrical power to the boiler / burner and shut off fuel oil supply.
2. Remove the vent pipe from the top of the boiler. Inspect the pipe and chimney for signs of corrosion and
deterioration. Clean out the base of the chimney. If the vent pipe shows any signs of corrosion or
deterioration, replace it immediately. If chimney damage or deterioration is discovered, contact a
competent professional.
3. Remove the top jacket panel screws (5), the brass wing nuts (2) holding the flue collector top, and then
the flue collector top. Inspect the gasket on the underside of the flue collector and replace as necessary.
Before beginning to clean the flue passageways, ensure that the combustion chamber blanket is covered,
[f the blanket is not covered prior to cleaning, replace the blanket once cleaning is completed.
Now with access to the flue passageways, remove the soot from the fireside surfaces by brushing
diagonally through the flue passages (see drawing below). Brushing can be made easier by cutting the
end of the flue brush off and inserting it into a drill. When brushing, care should be taken so as not to
damage the target wall with the flue brush.
6. Carefully vacuum the soot accumulations from the combustion chamber area, being particularly careful
to not damage any of the refractory or blanket insulation. To gain access to the combustion chamber first
double check that the shut off valve on the fuel oil line is closed and then disconnect the fuel oil line.
Then open the swing door by simply removing the whiz lock nut holding the door shut.
7. Now inspect the target wall, fire door refractory, and combustion chamber blanket (when included) for
cracking and deterioration. If there is any signs of cracking or deterioration, replace the refractory or
blanket before reassembling the burner / front plate.
8. Inspect the door’s braided gasket for wear and damage. Replaee when necessary with braided gasket of
the same material and size. See repairs parts section of this manual.
9. Now inspect and clean the oil burner.
