Intent 1:

To limit the probability that an excessively long, non-vertical run in the length of a flue will contribute to the cooling of flue gases, which could lead to an inadequate draft, which could lead to the spillage of combustion products into living space, which could lead to negative effects on the air quality of indoor spaces, which could lead to harm to persons.
