Intent

Intent 1:

To limit the probability that an inappropriate location or installation of fans will lead to:

  • zones of depressurization in the building, which could lead to the spillage of combustion products from fuel-fired appliances, and
  • the distribution of contaminants that might be present in boiler or furnace rooms by entraining them in the air being circulated in ductwork serving the building.

This is to limit the probability of negative effects on the air quality of indoor spaces, which could lead to harm to persons.
