Drill a hole in the flue at a distance from the boiler equivalent to twice the diameter of the flue to measure
combustion efficiency and combustion flue composition in accordance with the rules in force. Use this hole to
measure the following parameters:
• Combustion flue temperature
• Oxygen (O ) or carbon dioxide (CO
2
• Carbon monoxide (CO) concentration.
Measure the temperature of combustion air near the air inlet to the boiler. The necessary hole must be made by
the technician responsible for the heating system when the system is first started up, and must then be closed
to ensure that the flue remains properly sealed during normal operation.
Important! Close the flue test point
hole on completion of measurements.
