Figure 6: Location and Design of Heat Exchanger Cleanout Port
With access to the inside of the heat exchanger through the burner area, clean-out
openings, and vent pipe connection, it is possible to use a long, flexible wire brush and
an industrial type vacuum cleaner to remove any soot build-up. NOTE: A one inch
(outside diameter) vacuum cleaner hose will fit into the radiator, apprximatly 8’ will be
needed to reach completely around and into the front area between the cleanout ports.
To vacuum and brush the outer radiator of the heat exchanger, go through the clean-out
openings in both directions.
Flue and Chimney
At least once a year, thoroughly inspect the heat exchanger flue pipe, the vent connector,
the chimney, or vent, and the barometric damper for signs of sagging, loose connections,
excessive corrosion, and deterioration. Clean, repair, or replace any components for
continued safe and proper operation of the furnace.
