Boiler Safety

The stack, however, does not have to be purged. A basic rule of thumb: for every cubic foot of the heating chamber there should be four cubic feet of fresh air or inert gas passing through the purge airflow. Refer to the NFPA86 standard for more details. There are two basic purge requirements: purge airflow is adequate, and purge time satisfied.
