Intent
Intent 1: 
To limit the probability that the ignition of an oil- or gas-burning appliance will lead to a relatively sudden increase in flue pressure, which could lead to the spillage of combustion products from a solid-fuel-burning appliance into living space, which could lead to negative effects on the air quality of indoor spaces, which could lead to harm to persons.
