Oil Boiler Cleaning:

1. 

Shut off all electrical power to boiler / burner and shut 

off fuel oil supply.

2. 

Remove vent pipe from top of boiler. Inspect pipe and 

chimney for signs of corrosion and deterioration. Clean 

out base of chimney. If vent pipe shows any signs of 

corrosion or deterioration, replace it immediately. If 

chimney damage or deterioration is discovered, contact 

a service technician.

3. 

Remove top jacket panel screws (5), brass wing nuts 

(2) holding flue collector top, and flue collector top. In

-

spect gasket on underside of flue collector and replace 

as necessary. 

4. 

Before beginning to clean flue passageways, insure 

combustion chamber blanket is covered. If blanket is 

not covered prior to cleaning, replace blanket once 

cleaning is completed.

5. 

With access to flue passageways, remove soot from 

fireside surfaces by brushing diagonally through flue 

passages (see drawing below). Brushing can be made 

easier by cutting end of flue brush off and inserting 

it into drill. When brushing, take care to not damage 

target wall with flue brush.

6. 

Carefully vacuum soot accumulations from combus-

tion chamber area, take care to not damage any of 

refractory or blanket insulation. To gain access to 

combustion chamber first check that shut off valve 

on fuel oil line is closed and disconnect fuel oil line. 

Open swing door by removing whiz lock nut holding 

door shut.

7. 

Inspect target wall, fire door refractory, and com

-

bustion chamber blanket (when included) for crack-

ing and deterioration. If there are signs of crack-

ing or deterioration, replace refractory or blanket 

before reassembling burner / front plate.

8. 

Inspect door’s braided gasket for wear and dam-

age. Replace when necessary with braided gasket 

of same material and size. 

9. 

Inspect and clean oil burner.
