Intent

Intent 1:

To limit the probability that metal liners will be installed in appliances using fuels that are more likely to cause the accumulation of creosote, which could lead to chimney fires, which could lead to the heat-induced deformation and joint failure of metal flue liners, which could lead to the leakage of hot gases and flame, which could lead to the ignition of combustible building components, which could lead to damage to the building.
