| Intent | Intent 1: To limit the probability of inadequate strength to resist
the stresses induced by the thermal expansion and contraction of masonry chimneys,
which could lead to the delamination or cracking of stucco under gravity,
wind or impact loads, or freeze-thaw stresses. Where stucco
provides required protection from precipitation, this is to limit the probability
of precipitation or meltwater ingress, which could lead to the premature failure
of chimney liners, which could lead to the leakage of carbon monoxide gas
into living space, which could lead to negative effects on the air quality
of indoor spaces, which could lead to harm to persons.
