State-certified modular homes must comply with the provisions of this Section.
When a state certified manufactured home is factory equipped with a central system to regulate the quality of indoor air, the system must be operated according to the manufacturer's instructions and equipment specifications.
A cooking appliance must be equipped with a separate ventilating fan/hood, independent of other ventilating systems, with a minimum rating of 100 Cubic Feet per Minute (CFM). This equipment must exhaust at the outside of the home. This paragraph does not apply to microwave ovens, provided that:
Each bathroom with or without a tub or shower unit must be equipped with a separate ventilating fan, independent of other ventilating systems, with a minimum rating of 50 CFM. The fan must exhaust at the outside of the home and must be rated for sound at a maximum of 3 sone.
All clothes dryers must be vented directly to the outside. A clothes dryer may not be vented into a chimney.
Combustion air for a heating appliance must be drawn directly from the outdoors. This paragraph does not apply to a gas fireplace, provided that the manufacturer's instructions do not require that the gas fireplace be provided with combustion air from the outdoors.
Each chimney used to vent a heating appliance must be draft tested to ensure that no positive pressure is present in the chimney that would allow products of combustion to enter the home. Consideration shall be given to seasonal changes in draft.
