Flue Gas Dilution - Airflow Developments
To ensure a maximum of 1% CO 2 content at the outlet, the volume flow rate of diluted flue gases necessary for a given boiler can be calculated as follows: Flow rate in l/sec = 2.69 x rated input of boiler in kW. Where 2 metres of discharge ducting is not possible then the calculation is: Flow rate in l/sec = 4.44 x rated input of boiler in kW.

Gas-Fired Boilers | Building America Solution Center
The lowest efficiency boilers are atmospherically vented, Category I boilers. A Category I boiler operates with the flue at negative pressure with respect to the combustion appliance zone (CAZ), i.e., the room in which the boiler is located, and the stack temperature is above 140°F, which is hot enough to avoid condensation in the vent. The burner draws its combustion air from the CAZ.
