    a)         Heating Equipment.  The heating systems for most homes are provided with the duct systems installed.  On-site installation consists of connecting the crossover duct for multi-section homes.  Crossover ducts for multi-section homes must be supported aboveground, sealed to prevent air leaks and cut to length to avoid kinks.

    c)         Clothes dryer vents must exhaust outside the exterior of the home, or any perimeter foundation or skirting.  The exhaust duct must be adequately supported and sealed.  The installation of the duct must be in accordance with the manufacturer's instructions.
