turns on due to a pressure increase in the plenum. The result may be a rise in the measured O2 in the stack gas and
an increase in the Excess Air. In some sealed systems the fresh air drawn in through the breach may reduce the
combustion air available leading to an increase in the CO reading. If either of these situations are present it is
probable that there is a problem with the Heat Exchanger which may require additional testing and inspection.
NOTE: Many cracks are invisible to bore scopes or the naked eye, and only open or separate from pressure or
temperature changes during operations.
