Shut off all electrical power to boiler / burner and shut

off fuel oil supply.

Remove vent pipe from top of boiler. Inspect pipe and

chimney for signs of corrosion and deterioration. Clean

corrosion or deterioration, replace it immediately. If

chimney damage or deterioration is discovered, contact

a service technician.

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

not covered prior to cleaning, replace blanket once

nut holding door shut.
