OIL BOILER CLEANING:

off fuel oil supply.
2. Remove vent pipe from boiler top. 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 immediately. If
chimney damage or deterioration is discovered, contact
competent professional.

(2) holding flue collector top, and flue collector top. In-
spect gasket on underside of flue collector and replace

brush off and inserting into a drill. When brushing, take
care not to damage target wall with flue brush. See
figure 15.

chamber area, be careful not to damage any refrac-
tory or blanket insulation. To gain access to combustion
chamber first double check the shut off valve on fuel
oil line is closed and disconnect fuel oil line. Remove oil
burner from fire door. Remove fire door.

tion chamber blanket (when included) for cracking and
deterioration. If there is signs of cracking or deteriora-
tion, replace refractory or blanket before reassembling
