Design Calculation Of Gas Fired Boiler

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.
