To measure combustion efficiency and the toxicity of the products of combustion, the boiler is fitted with two dedicated test points.
One connection point is connected to the flue gas discharge circuit, and allows monitoring of the quality of the combustion
products and the combustion efficiency.
The other is connected to the combustion air intake circuit, allowing checking of any recycling of the combustion products in
case of coaxial pipelines.
The following parameters can be measured at the connection point on the flue gas circuit:
• temperature of the combustion products;
• oxygen (O
2
) or carbon dioxide (CO
2
) concentration;
• carbon monoxide (CO) concentration.
The temperature of the comburent air must be measured on the test point located on the air intake flue by inserting the mea-
surement sensor by about 3 cm.
